Title: Fixing My molten Roadster
Post by: markiii on March 13, 2006, 08:47
Well after tehe issues encountered at Anglesea I though it might be interesting to document the results of fixing my melting issues.

I'll update this thread as I go.

more to come.

What melted? And why?

I remember when Daz had an issue with his apexi turbo and melted all the plastics near,around and including the SMT fluid tank. Made a bit of a mess.   s:( :( s:(

However spent moday getting together all teh parts that I need to replace

so far not as bad as anticipated.

Mint rear bumper (needs painting)
rear upper grill
Suspension top mount dust cover

All in £40, cheers Adam,  s:D :D s:D  

popped of to MrT for a new release cable and clips for the rear deck, surprisingly only came to £18   s:D :D s:D  

part numbers for those interested

T69307-17080
T90467-13012

time for another update

Stu spent this morning helping me dismantle everything and remove teh manifold.

not good news.

1. Manifold-Turbo was secured with studs which had sheared and will need drilling out  s:-( :-( s:-(

2. Flexipipe to turbo has snapped where teh flexipipe welds in. So that will need fixing/replacing

3. manifold isn't wearing to well. I knew it needed recoating but the welds aren't wearing very well.

Hopefuly stu will have pics later on.

Sean, the pics you posted on Sc ref your manifold aren't far off mine so if you can post them here. ta

not a good day  s:-( :-( s:-(

Title:
Post by: markiii on March 18, 2006, 17:36
hopefull Stu has but I will take some soon.

I don't understand where teh tearing force has come from to shear them especially as teh other 2 would prevent twisting.

flexi pipe, I suspect Jays recent comment ref the flexi pipe breaking if your don't beef up teh engine mounts

shame he only mentions it now and not 12 months ago, also a shame it's not in teh manual for new purchasers  s:-( :-( s:-(

Tom changed exhaust and you have kirks mounts so hopefully you can avoid that.

However I would be concerned ref the studs, and teh condition of you manifold in general. you NEED that Turbo brace ASAP

I spent a good 15 mins working out if I could afford to drop another 4K and simply buy teh TTE

not finacially viable though so we struggle. on.

I am however less than impressed with long term durability of this kit
Title:

Put it this way: After seeing what has happened to yours and Sean's cars recently, I won't be driving mine again without a brace on it.
Title:
Post by: spit on March 18, 2006, 18:43
I thought you were braced Dan  s:? :? s:?

Bit of a mystery how you'd get the movement to shear 2 studs only Mark. All I can think of is that the 2 pairs/holes weren't exactly parallel, so 2 have been under extra sideways strain since install?

You've got me worried now - the Hass looks so much more industrial in construction than the C2. Must do a checkover. I think Kirk mounts are going to be a must-do though.

Damn Mark  s:( :( s:(  Not good.

If you can't get those studs out - remember the place that did the manifolds will spark erode the studs for £40 cash. Granted they're in Poole, but I'm sure I can get your manifold down there & back somehow  s;) ;) s;)

For the flexi section - 3S seem to have a good supplier of interlocking (solid segment inner) flexi sections in various sizes and lengths, and can get them welded in for a decent enough price.. Worth thinking about, anyhow.

But yes.. long term reliability of the Hass is not looking so hot right now  s:( :( s:(  (er, pardon the bad pun!)

sorry guys, no pictures other than the bit that mark didn't mention,the right light

(http://www.tandridgecanoe.co.uk/roadster/moltenlt.jpg)

Marks forgotten that were like a couple of old women when it comes to things, we spent the 3 1/2 hrs of stripping it, gossiping and bitching and as such forgot to take any pictures  s:oops: :oops: s:oops:  the bolts at the back have literally snapped, my thoughts are not that the flanges were drilled offset to each other as Ste suggested but that the thermal expansion of the metal as it ran lean literally snapped the studs off, it arguable as to wether it had happened recently or not as the front surface of what was left of the stud already had corrosion on it and more than i'd expect in a week. personally guys i'd now say that this had happened before Anglesey!

As for the rest of the manifold, well it looks as though theres another issue. At anglesey, Sean asked me to take some pictures of what appeared to be cracking in the seam welds but we couldn't see what was causing it as the ceramic coating was covering the area. Well on Marks one the coating has come away badly and you have a clear view of a potential issue. Thankfully in a way the ceramic coating protected most of the metal allowing the cracks to corrode and expose themselves. They appear to dissapear into the metal welds!!!!!  again my personal view is that they didn't clean up the metal before welding and its led to a weak spot that has started to crack, my expectations will be that it WILL seperate if given enough time and unless Hass improved there quality control, so will Dans and Tommy's. This is however fixable, were going to spend a few hours on Marks and investigate this a bit more by carefully grinding down one of the welds so that we can see how far the cracks go in. at the end of the day though it looks like a cut, clean and reweld job, but its something that just shouldn't happen.

watch this space i guess

Post by: Anonymous on March 19, 2006, 16:03
My opinion is that theres too much load through the relatively thin walled manifold. It has cracked at the weld due to local hardening of the metal that ocurrs during the welding process. The weight of the turbo and the fact that the turbo flange is beefy in comparison to the tube its welded to results in a large stress concentration factor at the change in material hardness at the weld. As the the forces generated by the turbo "bouncing up and down"  are in effect being disipated through this tube the result is failure at the weld. If you look at the amount of bracing on the stock manifold in comparison to the Haas it's obvious that more bracing is needed to support the weight of the turbo - which we kinda know now! I strongly suggest that other Haas owners check their manifolds and reinforce ASAP  s:wink: :wink: s:wink:

We're awaiting the pics Stu, and I'm told I'll need to mod my DP angle when I switch, but on the basis that its similar to the C2 welded log, there will be some differences to Hass: notably - turbo take-off is central rather than offset, and (because of this) no O2 sensors in the manifold.

Adapter plate will fit the Garrett - same unit - albeit a reverse orientation between C2 and Hass. And height/angle will of course be different. So feasible but not without issues.

I suppose if he is willing, and its viable, Gas could get hold of a retired Hass Manifold as a template for a new casting? I'm not sure how many C2 casts he is planning on shifting, but they're very reasonably priced  s:wink: :wink: s:wink:

Post by: markiii on May 5, 2006, 10:37
Time for an update

firstly how did it happen?

Having batted around a few thoughts with Hass owners on both sides of teh pond I have a working theory.

As standard Jay ships teh kit without a turbo support which in turn puts all of teh strain on teh manifold studs.

Under power the engine tries to rotate downwards and the exhaust fights this. End resut is that teh manifold tried to pivot upwards on teh studs.

Typically this has resulted in stripped studs in a number of instances.


Following Seans having this issue we both had turbo braces made to teh same design to keep the turbo against the block and prevent stripped studs.

however;

We had the brace on teh left hand side of teh turbo. The Hass exhaust exits on the right hand side of teh turbo.

Follow teh same scenario again, engine rotates down (or tries too) but the brace prevents the manifold moving relative to teh block. However it exerts force on teh left hand side of teh turbo. The exhaust tries to fight the downward motion by pulling backwards on teh right hand side of teh turbo.

Effectively a torsional load is placed on teh turbo as it attempts to twist clockwise relative to teh manifold. Obviously it cant, but all of teh torsional stress is now located on the manifold/turbo joint.

On inspection the only stud between turbo and manifold intact on mine was the one around which this pivoting motion would occur. 2 others sheared clean off and the 4th was bent like a banana.

lending credence to teh theory.

Seans issues above occur at what I would consider the next weakest point the mainfold weld. So assuming that his studs coped better than mine (for whatever reason) the next point of failure is exactly where his weld is failing.

Additionally teh only other person to have braced a Hass yet is WTS in the US, and he braced his on teh right hand side of teh turbo. This should prevent teh issue as teh opposig pull forces are now directly opposed and no torsional stress is applied.


Lesson learned Brace Both sides of teh Turbo.   s:cry: :cry: s:cry:  

Fortunately Dan had this done before he sold his car and I've since bought that brace off him.  s:D :D s:D  


We also discovered o dissasembly that my flexi joint had ripped apart. The Hass Flexi is on teh exhaust to teh right of teh turbo. And as such is subject to the same opposing forces when teh engine attempts to rotate.

Jay has since advised everyone to fit harder engine mounts to prevent this, but I dare say running 10psi and booting it into first on teh hairpin made this one my own fault   s:oops: :oops: s:oops:  


Curious as to how this issue affect other Turbo kits I did some digging

PE, Top Secret, and the TTE ALL have there kits designed so that they mate back up with teh stock CAT. I've always wondered why teh stock CAT takes teh odd route down and under teh grey cross member but am now convinced it is so that the flexi joints get compressed as teh engine trys to rotate, thus preventing them from tearing.

Nice design feature guys.

Looking at teh C2 I beleive it could be sligtly more problematic than teh TTE,PE, Top secret, but is way better than the Hass design in this respect. (Stu don't panic it will be fine)

So what next?

Having wired brushed down my manifold welds they looked OK to me. However rather than take the risk and spend more money coating a potentially suspect manifold it was time to call in teh experts.

in teh form of H&S.

Thanks to Lee for droppig it in for me.

The guys at H&S couldn't see an issue with teh welds short of getting it xrayed but were slightly concerned that teh manifold flange had only been welded around teh outside edge and nothing at all on teh inside edge.

However for £20 they fixed it for me and did a blinding job too.

see below.

(http://www.mr2roc.org/Repository/misc/userpics/markiii/hsweld.jpg)

so thanks to Lee and H&S

next job was to remove teh sheared studs and boy was that a pain. The studs themselves were so soft that easy outs just ripped back out again, leaving no alternative but to very carefully drill out teh studs. I reckon I got lucky on this one and with some very careful use of a Tap was able to clear out the thread just fine.

Worth noting is that while an American kit these holes are standard Metric M8 with a 1.25mm thread.

So finally I finished Monday with a manifold now ready to be recoated.

see below

(http://www.mr2roc.org/Repository/misc/userpics/markiii/fixedstuds.jpg)

Thanks to Lee, Ste, and Tom  for suggesting Camcoat as they are going to recoat  it with their black satin triplecoat for £100, bargain  :-) :-) :-)

Manifold is now all wrapped and being sent off this week. Estimated turnaround is 2 weeks.

Next job is to change the molten release cable for teh engine deck.

Stay tuned

Post by: spit on May 5, 2006, 13:40
Thanks for the update Mark. Having seen how substantial the Hass pipework is in comparison to the C2, I've been getting worried about this.

Its amazing though that bracing the turbo off-centre would lead to this kind of catastrophic failure. Is there only a limited amount of flex in the flexi and exhaust hanger arrangement?

I'm trying to relate what happened to you to the early C2 design. Not good at physics but I may be unwittingly OK!

My brace is not physically connected to the turbo housing   s:oops: :oops: s:oops:  That might be a good thing....... I'd already ceramic coated when the brace arrived and I discovered that when everything was offered up the brace nestled nicely (and tightly) dead centre under the base of the casting.

More luck than judgement, but this supports the weight of the turbo and allows any twisting forces to be absorbed by the bits that are designed to absorb them ie the flexi joint and rubber exhaust hangers.

.....but I'll keep an eye on it  s:roll: :roll: s:roll:  ....particularly cos I'm still on stock engine mounts  s:shock: :shock: s:shock:
Title:
Post by: markiii on May 5, 2006, 13:53
Ste,

From memory the C2 exhaust design allows a little more give.

The HASS flexi while I reckon able to absorb a compression movement isn't vwery stretchy at all.

My intention is to replace with an 8-10" section of higher quality flexi, perhaps with a small kink to alleviate this.

thinking about it Martin's old Turbo (Now with BenF) was PE based and he replaced teh whole exhaust with a custom jobby which changed teh design of teh flexi.

As a result he cracked it at least 5 times. His exasperated exhaust shop eventually put around 2 feet of flexi in and it hasn't gone since.

ref teh engine mounts for $40 they really are a no brainer

Post by: Anonymous on May 6, 2006, 07:50
Nice writeup!
My problem all involved cylinder head studs and happened within 2000 miles of the turbo installation. These all occured before bracing and before kirkosaurus motor mount inserts were added.

The bottom centre stud fell out like a dead tooth and that makes sense if the engine twists back and down under acceleration. The bottom edge of the exhaust flange would act as a jerking lever against it.

The 2nd exhaust manifold stud to go was on the far right (your drivers).
It simply sheared in two. Possibly from thermal expansion. I just put another one in its place thats been OK ever since.

3rd stud to strip was the upper middle left . Head threads came out with it.
Its brother to the right immediatly suffered the same fate as I gave it a viscious crank with a biggish spanner. Just twisted it right out of the block.
Drove it to my buddies shop with all 3 center studs missing and there was no exhaust leak.

Am redoing everything this summer and will look at new bracing options as well.
Any pics of your £200 brace?
Mines just a $1.50 worth of mild steel.

Post by: spit on May 6, 2006, 10:49
Looking through the TTE install manual it just shows how much more sensible the layout is. Not only is the Turbo braced dead-centre underneath, but making the DP into a full U-bend to retain the stock Cat position makes for a very clever alignment. The stock Cat flexi pair must be pretty decent to cope with the extra vigour of stretching under boost though. I'm sure this has been engineered to be FFP.

Because us non-TTET guys all have more off-centre forces in play, I think capacity for both compression and stretch needs to be looked at on our kits. I'm getting worried again cos my exhaust isn't as free-hanging as I'd like it to be (remember those awful twin-tip alignment issues I had?) and the DP flexi isn't as mobile as the twin stockers.

Worth keeping an eye on........  s:roll: :roll: s:roll:

Post by: spit on May 7, 2006, 14:28
Its something we're just going to have to keep an eye on for now, Phil.

hate those things).

I figured the twisting etc might have caused it, but on closer inspection it turns out the hole in the DP flange is "dished" (in a saddle-type stylee)   s:shock: :shock: s:shock:  The head of the old bolt was only mating with the flange at two points, so no wonder it rode loose. Turns out I've lost 2 of the 5, but all replaced now and I'm carrying stock  s:lol: :lol: s:lol:  

Also loose was one of the Mani-Turbo fastenings. Tweaked up and nutlocked..... but I'm gonna have to review these fixings soon I reckon. You're on a stud Phil, aren't you?  s:P :P s:P  [/list]

Anyhoo, back to the twisting - I tried to gauge the twisting from a reverse angle......by lifting the o/s exhaust tip. This causes the engine to move  s:? :? s:?  The flexi absorbs some of it but I'm concluding that it probably isn't enough.

So I'd also value the guru thoughts and any preventative maintenance ideas.

Also, I would recommend torquing your bolts down during intitial buliding, and re-torquing them when hot.

Wont stop them coming loose though. Which is 90% of the battle. You need something to stop them coming loose in the first place.

sorry Grant, i'm interested as to why would you say that, the whole point of wirelocking is to stop them coming undone in the first place

One to many late night call ins for items of power plant that have fallen to bits, and were previously held together with wirelocking...  s:evil: :evil: s:evil:   Wirelocks always leave scope for the fastener to move, even its just a little bit, and that can ruin the integrity of the joint you're trying to keep together.. Thats just my experience in my industry though, I appreciate you're in a slightly more delicate field of engineering than myself, that makes very good and reliable use of wirelocking.

In its place though, we have substituted a number of measures that seom might say were a little more agricultural than wirelocking, but they have a 100% success rate. Other than the use of threadlocking gunk, theres the use of Nordlock washers, and the slightly more permanaent practice of of tourquing a bolt down, and then tack welding it in place. Not something you're likely to see on an aircraft any time soon I know, but my jet engine here wieghs about the same as a fully laden jumbo!

Post by: kanujunkie on May 7, 2006, 22:24
aaaaahhhh, i see what you mean, the type of wirelocking i do does allow up to 30degs of rotation before it locks, i'm hopeing that it will be enough along with high temp thread locker, lock washers and anything else i can think of

How about Tab washers? Cheap, effective, and allow a lot less movement than 30 Degrees, which is quite alot...

Put it this way, on a standard M10 thread, 30 degrees of movement is just over 1/10th of a mm gap opened up in the joint... Its not huge, and it may not leak, but it just beacame a potential weak point without ever compromising the wirelock.
Title:
Post by: spit on May 7, 2006, 23:24
Tab washers and Allen bolts don't go well together though do they?

I've never liked Allens for anything other than lightly-torqued cover plates or cosmetics (eg mo'bike clutch covers etc). I just don't think they're appropriate for torqued applications with high temp variance.

Be interested to see how you get on with wire-locking Stu.

Just to put this into perspective, I'm 11,000 miles in and the body count is pretty low considering no locking other than a blob of blue:

  s:arrow: :arrow: s:arrow:  Manifold stock nuts (x5) - INTACT
  s:arrow: :arrow: s:arrow:  Manifold-T allen bolt and 13mm nut (x4) - INTACT but 1 finger-loose, now tightened
  s:arrow: :arrow: s:arrow:  T-DP allen bolts M8x25 (x3) - 2 AWOL (? due to "saddled" hole), now replaced
  s:arrow: :arrow: s:arrow:  T-DP allen bolts M6x20 (x2) - INTACT
  s:arrow: :arrow: s:arrow:  DP-Exhaust Nut and Bolt (x2) - INTACT

[Oil feed T-piece cobbled tap washer (x1) - INTACT-ish  s:wink: :wink: s:wink:  ]

Leaks - NONE

But of course this could all change very rapidly and catastrophically  s:oops: :oops: s:oops:

Quote from: "GSB"The best threadlocking device I have ever-ever used, bar none, is the Nordlock... Its better than spring washers, its better than split-pins, nylocs, double bolting... etc..  These are, quite simply, the best...

They woork by untilising a system that means that if the nut wants to undo, due to vibration, thermal cycling etc, then the joint actually has to get tighter to do it... They are brilliant...

RS Sell them.   w www.rswww.com (http://www.rswww.com) w

Not sure if you need an account or not, but they're roughly £10+VAT for a box of 50 for sizes M3, M4, M5, M6, M8 & M10, and then the same sort of cost for a box of 10 in sizes M12, M16 and M20.

What sizes are actually needed? I'll have a dig around in my washer bin and see what I have left over here.

Sean (or anyone) - can these be used to good effect at the head of bolts rather than on nuts?

I can't see why not, but you guys will probably know better.

I'm thinking for the M8s that I have holding the T-DP flange together (where the Garrett has blind threaded holes) aswell as the Manifold side.

Another constraint might be the diameter of these things - there isn't much clearance around my flange plate holes, so they might be fouled by the Flange/DP body weld rather than sit flush  s:? :? s:?

just to bring this back on topic

manifold is now back from camcoat, and they've done a very nice job.

(http://www.mr2roc.org/Repository/misc/userpics/markiii/coatedmanifold.jpg)

Stu and I stripped and cleaned everything in sight yesterday (cheers bud), cleaned teh whole block fitted the krankvents and catchcan, and had a general tidy up.

I've just been to Nissan and bought there gaskets for manifold to turbo and turbo to exhaust as they are much better than teh pressed tinfoil Garrett jobbies (thanks to Aarron for trawling part numbers for me.

for anyone else reading this later

Turbo to Manifold is a rectangular 4 bolt flange, Nissan part number for this on teh S14 200SX is 1441575F10 and comes in at £12.70
(http://www.mr2roc.org/Repository/misc/userpics/markiii/nissanturbogasket.jpg)
Turbo to exhaust (odd shaped 5 bolt affair) Nissan part number for the s14 200SX 1444575F10 cost £16.48
(http://www.mr2roc.org/Repository/misc/userpics/markiii/nissanexhaustgasket.jpg)
These fit standard GT28 Family Garret Turbos including those on teh Hass and C2 kits

the reason for using these is that they are propper crush gaskets.

Since I'm rebuilding I figured I may as well do it right.

having cut down some oversize studs too fit today I refitted the manifold to teh turbo, (with nordlocks) and re bolted everything to teh block.

and as promised here is a pic of teh brace that goes to teh right hand side of teh turbo

a mate called in yesterday who happens to be a welder by profession and I asked his opinion on my broken flexi joint, see pics below

(http://www.mr2roc.org/Repository/misc/userpics/markiii/flexiflange.jpg)

(http://www.mr2roc.org/Repository/misc/userpics/markiii/flexi.jpg)

interstingly he commented that teh flexi never appeared to have been welded to it's flange and appeared to have been purely a tight push fit.?

anyone else car to comment? before I pop it over to H&S for comment?

I'm no expert on welding by any means, but I'm a dab hand with a soldering gun and those bits look like they've never been near a flame in their life. How I didn't spot that the many times I've actually seen those bits in person, I'll never know.

You'd expect to see bits of weld still stuck to either the pipe or the flexi if welding had taken place and it had simply come apart under stress, but there's nothing there at all.



Weird. Or maybe not, going on previous Hass work. I can say stuff like that now I no longer own one.  s:wink: :wink: s:wink:

my mate theorised that they may have been sweated on, get it really hot attach and the as it cools it contracts.

which while possible seems stupid for where it goes, the whole joint is going to be under tension every time you drop the hammer.

good news is I emailed teh pics to H&S today and Ian reckons it can likely be welded.

Just revisited the C2 flexi. Unless its welded inside at the distal ends of inner and outer flange its the same arrangement as yours Mark. Are H&S going to split the outer flange from the DP and do the same, or try to weld it around the lip of the flexi mesh?  s:shock: :shock: s:shock:

right just got back from H&S and teh good news is that for £20 they managed to fix it   s:lol: :lol: s:lol:  

the bad news is that the Hass exhaust is actually mild steel not stainless, I can't find anywhere on teh Hass website where it actually says stainless but that was certainly my expectation.   s:cry: :cry: s:cry:  

the humorous news was watching Ians face when he saw teh exhaust, I don't think he new wether to laugh or cry, but uiffice to say impressed he was not.

coouple more updates

Ste,

they fixed teh flexi by drilling several holes through teh flange that had seperated. Pushing them back together and then weldeding teh hoels and teh seam.

Steve,

Turbo template below. I've added dimensions in places to allow you to size it right

(http://www.mr2roc.org/Repository/misc/userpics/markiii/turbobracetemplate.jpg)

the hole on teh right with 2 circles has 2 bolts welded to it to space it sufficiently. This allows it to bolt through the mounting hole below teh pulley mount on teh block. The other 2 holes goe between teh exhaust flange (off teh turbo) and teh bolts holding it together.

looking much better I'm sure you will agree.

I then painted it and added some polished stainless tips (£9.99 each courtesy of ebay  :-) :-) :-) )

looking even better

next job is to wrap and seal, however as I didn't buy sufficient wrap I'm waiting for more to arrive tommorow to complete the job.

in teh interim I resoldered teh injector pins (2 were mullered) installed the breather filter and crankvent (see below)

the 2 front holes should have holes in teh cam cover into which plastic pop fasteneings  originally go.

however these almost alwasy break on removal, I simply drilled out the snapped plastic, tapped the hole with an M6 tap and fastened back on withsome stainless M6 allen bolts, I got them from screwfix, though they only sell them in volume. I have spares if you need them.

the rears are studs that go through from teh cam cover.

these are also M6, I got teh nuts from Wicks, and they are a couple of quid for a pack of 10.

yeah thanks Stu, for yesterdays mammoth session, don't think you left till 0030

we got teh new rear bumper on, exhaust in, fabbed a completely new intake to allow use of an Apexi filter, had a nihgtmare getting teh support tool to work to download the new emanage map, upgraded to teh new MAF post turbo layout and and buttoned everything back up.

only snag was teh exhaust wrap putout so much smoke we though she was on fire at one point.

and the exhaust is still way to loud.

now if I can just get it MOTed before Friday we are sorted  :-) :-) :-)

pics to follow

one question I do need to solve is why it now idles at 1200rpm

pre rebuild (new map and MAF location)

it idled more or less solid at 750rpm

I left it 15 mins while mowing the front lawn this orning and while its consistent 1200rpm seems way too high.

any ideas?

Have you gone through the idle re-learn procedure in the BGB?

Post by: markiii on July 16, 2006, 13:05

Post by: Slacey on July 16, 2006, 14:13
Mark, allow it to warm up (and idle high) then switch off. Leave for one minute and restart, it will drop to the usual 750 and will stay there for good. If you reset the ECU, it will do the 1200 thing again - mine did this after every reset, but I needed to do was switch off then on again when warm.

Simple - you probably reset the ECU.  When I did this to mine after installing the new pipes, it did the same thing for about 2 days.  Then all of a sudden it "learned" and all is well.  This has happened each time I cleaned the maf and reset the ECU.

Glad to hear you are getting it all together.  I am adding the krank vents today and finish wrapping the exhaust.

Post by: markiii on July 16, 2006, 15:42
thanks guys I'll try that next

just finished installing teh Kirks mounts
following Seans install tips  m http://www.mr2roc.org/phpBB2/posting.ph ... ply&t=7588 (http://www.mr2roc.org/phpBB2/posting.php?mode=reply&t=7588) m

since i've got teh pit I used a piece of 2 x 4 to brace teh gearbox which made teh rear munt easy, nothing moved at all.

the front mount was a PITA, the right hand bolt not wanting to line up with the thread, took 30 mins of cursing before it finally went in.

now to see wether teh vibration is as bad as I hear it can be or as unoticable as Dan and Seans were
Title:
Post by: spit on July 16, 2006, 17:04
Good luck Mark - mine have settled down a little since install, but there's still a nice vibro-massage thing going on with the seat backs and a hideous drumming at low revs..... not to mention the need to carry spare Dev's keyhole covers  s:wink: :wink: s:wink:  

Oh, and the most bizarre side-effect I get with the Kirks is the fuel flap popping itself open every now and then  s:lol: :lol: s:lol:  

Apart from that they're the dog's.
Title:
Post by: markiii on July 16, 2006, 22:18
well the mounts are in, and teh vibration isn't as bad as expected.

however coupled with the Nascar level exhaust it could I feel be like sitting in a tumble dryer. Compunded by teh resonance effect of teh hardtop.

however as the plus points are so good, i.e fabulously slick shifting and instant power I think they can stay for the time being. That exhaust is definately getting changed though.

guys went out for a quick blat last night to burn of some smoke from teh heatwrap

and I notice that the profec things I hit 8.6psi even though it's turned off and I'm at wastegate pressure.

I remember Stu revesed teh pressure valve connections on teh basis it wouldn't matter but I'm starting to think it does

any thoughts?

my bad profec boost controller

Post by: kanujunkie on July 17, 2006, 18:55
perhaps you were right then Mark, i thought the profec valve didn't have an NRV in it, i thought it was a straight air switch. Can anyone confirm??
Title:
Post by: markiii on July 17, 2006, 19:01
my gut says it does but my brain can't decide why at the moment

swap them around then and go for a drive, it'll prove the NRV bit

ok swapped,  number plate lights are plugged in and the MOT is booked for tommorow afternoon.

2 concerns

emissions, if ti fails on that I'm buggered for JAE and airbag warning light

seems to be debatable as to wether teh latter is part of teh test or not

well we have good new, good news and bad news

well the good news is it passed it's mot   s:D :D s:D  

though apparently the airbags become part of teh MOT as of next week, so that was close.

Tax next and we are set for JAE   s:D :D s:D  

good news is that following a long run today teh idle has now sorted itself out at a rock steady 750rpm as per previously   s:D :D s:D  

however the boostguage is still reading odd, reckons I hit 8.1 psi today and thats nowhere near accurate   s:roll: :roll: s:roll:  

think I need to compare with Steves at JAE and compare the plumbing

Post by: Anonymous on July 18, 2006, 18:49
Excellent news mate! Now all I need is for Steve's to pass his and I'll have got rid of the car for nothing!  s:( :( s:(   s:lol: :lol: s:lol:


Damn lucky about the airbags though: I reckon it was destiny for you to get the car fixed by this week  s8) 8) s8)

Post by: markiii on July 18, 2006, 19:16
thanks Dan, don't know about destiny more liek team work

primarily thanks to Stu for giving up so much time to assist,

and additionally to yourself, Sean, Aaron, Lee, and Grant

and of course Adam for parts  :-) :-) :-)

just done a total of what it cost to fix

Bumper and Grill £40
Release Cable £18
Welding Manifold £20
Gasket £12.70
Gasket £16.48
Paintwork £150

Total cost to get it back to pre Anglesey £257.18 thats not bad   s:D :D s:D  

additionals not necessary but done while it was in bits

Heat Wrap £100
Paint £30

Total £230

Mark, good to see you've got the car fixed, and look forwards to seeing it out on track again soon  - £230 for the parts is very, very good!

I'll definitely be looking fowards to a nose around it this weekend to see what you've done - I'm tempted to get some exhaust wrap for mine as I've noticed the intake temps getting high in slow traffic as the exhaust is close to the intake filter.

One thing I noticed from the pics - are you really using cable ties to keep the exhaust wrap in place ...?

Not worth a new thread, and someone reading this will know the answer  s:wink: :wink: s:wink:  

Can you re-use Nordlock washers, or will they fall apart when I take the manifold off?
Title:
Post by: GSB on July 26, 2006, 20:35
Nord-locks are completley reusable, just remember to put both washers back under the nut when you refasten, as they dont work when not installed in pairs.
