Hello all!
Following on from my introduction I'm creating this little thread to follow the progress of my Silver 2003 MR2 with HASS turbo kit.
I bought it with the turbo kit fitted, but have plans to strip it somewhat and get it ready for the Scottish Sprint and Hillclimb 2016 Championship and run in Class A8 for Road Marque Cars such as S2Ks, Elises, VX220s, Z3s, TVRs, MX5s and even mk2 mr2 turbos!
I have entered the Wigton Cross Border Sprint at Kames on the 4th of October. So my aim is to get the car ready for then as part of it's first shakedown in preparation for next season. I know the track pretty well and my personal best is a 79.55s for the 3 laps, but that was in my old single seater, so I'm aiming for anything under 100s really!
I do have an E46 320d M Sport as my daily driver, but I did use the mr2 for the first week I got it, but being stuck in traffic jams with a stage 3 clutch isn't much fun. So it's weekend and track toy only I fear. I need to study the road car regulations in the MSA blue book to see how much I can strip out of the car and it still be classified as a "road" car.
As far as I know (from what I've been told and researched from old threads on here) here is the current spec:
• HASS Turbo Manifold
• Garrett GT28RS Turbo
• Stage 3 ACT clutch
• 440cc injectors
• Custom 3inch dual exit exhaust
• Greddy Emanage Blue
• Greddy E-01 (linked to EMB with 3 diff. maps)
• Greddy Profec B-Spec Boost controller
• Boot mounted intercooler
• Porche 911 OEM BoV
• Digital Air/Fuel meter
• AFAIK std internal 1zz-fe engine

[centre:244laszy]Step1 - Coilovers![/centre:244laszy]
Went for some BC Racing Type Ra coilovers with 5/7 springs. I don't think I've paid more for a set of shocks in my life, in fact I've bought cars with less money! s:oops: :oops: s:oops: s:D :D s:D
An early start saw me in Clackmannan this morning at "The Garage" to utilise their ramps for the suspension swap. Ian Murray at The Garage was my team sponsor when I was racing the single seater and I've been using his services for a decade now. I've never proclaimed to be a mechanic but I've picked up a few skills along the way watching Ian and I generally like him to go over any of my work in case I've c0ck3d up somewhere s:D :D s:D
Anyway, even after stopping for a roll at half 10 I had the old suspension off and the new coilovers on by midday! No swear words or broken nut in sight! Well happy!
I haven't adjusted the ride height as yet, but it is noticeably lower than stock, and I can still get over the massive speed bumps in my street! So I'll wait a few days till everything has settled before adjusting anything more. I set the fronts on 10 clicks from full soft, and rears at 15 clicks from full soft. It was probably too harsh driving home but the control and feeling of the car was phenomenal in comparison to stock.
I've got caster bolts coming on Monday along with EBC yellow stuff pads too. So I'll need to get the car booked in for alignment before the 4th, but before even that I've still not decided if I want to stick with 15/16 inch wheels or go for 15s all round! Still researching this one but with my style of driving I'm thinking about squaring it all off!

Awesome bit of kit. Bet that's a hoot to drive
I haven't long started sprinting myself and love it.
Going to be doing the Welsh kne along side the tss one next year but so far this year it's great.
I recommend gt-4 play for parts as many do on here.
Welcome along too
The suspension is nice to work on thankfully. How did you get on with the rear drop links? (not tear drops!)
Really interested in seeing how things go with this, I've thought about hill climbs myself
You know I did try to get on to the gt-4play website at work but it was blocked under *sex* category - wtf?" lol I'll need to get it unblocked and will order for them next time.

To be honest I prefer hillclimbs to sprints. It's point A to point B in the fastest time possible, and the hill brings other things into play like momentum; that half a second you lost at the bottom of the hill actually equates to 2 seconds by the time you reach the top. s:cry: :cry: s:cry:
Drop links came off easy enough. The guy that had it before me had previously stripped the entire car as he was turning it into one of his Turismo Mr2s, but he put it back to stock with body panels and suspension from a TF300, so pretty much every nut and bolt was a breeze. s:D :D s:D
Ooh! I remember that car now! Well that made your life easy, well done s:) :) s:)
What is next on the list to do / upgrade?
I've got Yellow stuff pads and a short shifter kit coming tomorrow. Liking the reviews of the HEL brakeline kit so might add that to my list.
Are the seats mounts still available from Rougue btw? Might give them a phone tomorrow.
Good choices, and yes the braided hoses are worth doing in my opinion.
Yes they still sell the seat mounts s:) :) s:)
Cheers. I'm still looking at seats but I'm struggling with the term Fully Trimmed in the MSA blue book...
I'll also mention I'll be changing the current intercooler and it's location as I can't see it being of much benefit where it is just now. Will update later with some pics!

At a guess the whole 4 Play thing might get web blockers excited?
I can assure you there is only car porn on the site s:) :) s:)
I hope it's only car p0rn! s;-) ;-) s;-)
Will probably be dropping an order your way tomorrow once I decide on a colour scheme. Have you got all colours of the HEL brake lines in stock? s:D :D s:D
Sorry, bit of a dark phone pic but you get the idea.
(http://section-1.co.uk/mr2/inter.jpg)
A chargecooler setup is normally more efficient than an intercooler on our cars so might be worth a look.
Radiator down the front and run it all the way to the back?
Worried about the extra weight versus extra performance tbh. Water, pump, extra pipes...
Very true, a large intercooler with bolt on fans would cut the weight and help alot it would be noisy tho.
Got some bucket seats on the cheap today. Will need to fabricate some mounts though as I didn't realise the subframe on my existing seats is attached to the seat upright.
On the upside the new seats weigh half as much as the old ones s:D :D s:D
Are these leather seats with the mr2 roadster embossed come as standard?
(http://section-1.co.uk/mr2/seat.jpg)
Sure are.
Im running chargecooler at the back and chargecooler ran at front.

Rogue Motorsport sell the seat mounts. It's the neatest solution...trust me I tried!
Yup I also have rogue seat mounts , tried and tested.
Quick question , where you getting your cage from as msa regs show you will need one minimum of half so that's roll hoop and rear stays
I went for the ppcages one after I saw meeerrrks one and I had been messed about by a local
Builder.
The price was more than what most had paid as they had a price increase but was well worth it
No cage required as I am doing sprints and hillclimbs in the road going class. It is recommended and I will get one eventually but not just yet. Would rather a hardtop first.
For the Welsh one even in street all covertibles must have a roll bar, damn it I'm
Coming to scotland
you're welcome anytime!
You made me check the regs in the MSA Blue Book again lol:
Sprint and Hill Climb Vehicles
10.
10.1.2.
Road-Going Series Production and Road-Going
Specialist Production, K.1.6.1 or K.1.6.2 recommended.
What really worries me is what I CAN'T remove according to the Regulations:
11.4.1.
Silhouette of the vehicle must remain unaltered
in construction, dimension and material. The silhouette
will be taken in the condition in which the car competes
(convertible closed cars competing with the hood or
top not erected shall have the silhouette determined in
that condition).
11.4.2.
Engine bonnet/cover and luggage/boot cover
may be replaced with an alternative material.
11.4.3.
Laminated windscreens permitted but all other
glass may not be replaced by another material.
11.4.6.
Interior trim must remain fitted (except floor
carpets/mats).
11.4.7.
All working equipment fitted as standard (heater,
window mechanisms, sunroof, door handles) must
remain operable at all times
Does that mean that the soft top has to stay, even if a hardtop is fitted?
If so, having a hardtop seems a waste as its just extra weight.
It's confusing sometimes
For example
For street class I still needed a cage but the interior must stay in but I would have to rip it out for the cage to fit so I went pro instead as the car was already stripped.
Best thing to do is meet with someone who competes and organises so they can tell you what's best.
The guy who runs the local sprints here lives down the road so I can go see him with ease for next year.
Wierd thing is that the first round of the Welsh speint and hill climb is at rockingham lmao and the rest are back in Wales
Quote from: "Jrichards20"Does that mean that the soft top has to stay, even if a hardtop is fitted?
If so, having a hardtop seems a waste as its just extra weight.
No, I don't think so. We have an A9 class up here in Scotland that is just for mk1 and 2 mx5s and they all take the soft top out and stick a hardtop on it.
Soft top weighs a lot too I was shocked how heavy it was when I took it off.
Sneak into the mx5 class with some badges and abuse them
Front strut brace added and some weight lost.
(http://section-1.co.uk/mr2/front.jpg)
It's good to see under your plastics that ur car has corroded in all the same places as mine. I got a bit depressed looking at mine but feel better now s:D :D s:D
They all do it s:( :( s:(
Yeh, am tempted to repaint all the black another colour over the winter but I'm in a bit of a rush to get the car ready for the 4th.
Quickshift finally fitted after I managed to lose a split pin. Need a new gearknob though. My one from my old mx-5 doesn't fit and the insert is fixed in somehow.
(http://section-1.co.uk/mr2/quickshift.jpg)
Have u tried it yet? Is it smooth?
Not driving on the road yet as I'm still seatless, but it does feel a lot more direct and shorter.
Fitted the standard driver seats back in and took it to my friendly garage today and fitted some yellow stuff pads all round.
With the addition of the quickshift, which has made a big difference, the car feels so much better. Gonna try and get the tracking done during the week along with seat mounts in preparation for a week tomorrow. Can't wait!
(http://section-1.co.uk/mr2/yellow.jpg)
Mid week update!
I've taken the day off work tomorrow to go and pick up a set of wheels and get them to the painters in time for the weekend. My race rubber has also been ordered and should arrive before Friday with any luck.
Still got lots to do before the Sprint race on Sunday. Speaking of which the numbers and details of who is in each class got released and I'm in good company. I've got 2 Mk2 Tubbys and a Noble M12 in my class! Should be fun! s:D :D s:D
Sounds good, I hope the rest of your prep goes smoothly!
Which tyres are you using? Let us know how you go!
Going for MaxSport RB5s. Can only get 205 and 195 widths in 16s so going to try that at the weekend and see how I get on.
MG/Rover 4x100 16inch alloys will fit fine yeh?
Seat fitted. Will put up pics tomorrow. Meanwhile I've been reworking the CHS Racing logo with a new design for the Mr2 s:D :D s:D Can anyone guess what logo it used to be?
(http://section-1.co.uk/mr2/chslogo.jpg)
Wheels painted, tyres fitted!
(http://section-1.co.uk/mr2/tyres.jpg)
I've thought about getting some of those. But was worried about weight. How much do they weigh per corner?
Quote from: "Swan_Connery"Wheels painted, tyres fitted!
(http://section-1.co.uk/mr2/tyres.jpg)
Nice looking tyres interested to see how you find them. Are they road legal?
If they are RB4 f3s then yeah road legal. They are remoulds so would be interesting to know how well they perform.

Quote from: "Jrichards20"If they are RB4 f3s then yeah road legal. They are remoulds so would be interesting to know how well they perform.
Yeh, they are. Had them on my previous Mx-5 and they are excellent for the dry. Horrific in the wet, and tbh I wouldn't/couldn't use them as a road tyre due to the horrific road noise.

Did you try any others on the mx5 to compare?
How do they compare in cost in comparison to an r888?

Only tried 888s, Nankangs and toyo proxies with the 5, and maxsport was definitely the best in the dry. Toyos were the worst.
Bit gutted today. Lost out to a mark2 mr2 turbo by 2 hundredths of a second! I did a 97.19 and he did a 97.17. So at least I beat my target of sub 100 seconds but was really struggling in practice with my brakes. Coming up to any corner and the left side brakes were locking solid and sending me off to the right. It was as if the abs was kicking into early and not releasing. Anyway, I took the fuse out the abs and ran like that for the rest of the day and it was much better.
When I was on boost I was quick, but in the hairpin and slower corners I was really slow. I was literally nailing the throttle at the corner entry so the power was there for corner exit. I think some smaller pipework to the intercooler may be in order to reduce the lag!
The only other issue I had was with the gears. I was only using 2nd and 3rd but was really struggling to get down to 2nd to 3rd even with a bit a heel toeing. Is this expected, or am I just used to flatshifting with the single seater?

I'm surprised you thought the toyo were bad.
I'm tempted by these but they aren't as cheap as it appears they used to be.
Anyway it sounds like you did well today, I'm sure it's a good basis to start from
I'd use toyo proxies on the road no problem. They just didnt feel great on track. Might be my driving style though!
Good effort, that's very close to the mk2 turbo, they don't hang around!
For the boost taking a long time to arrive I would consider a GReddy profec B or similar boost controller - you can dial in exactly the same boost as it currently makes, but it can stop the waste gate creeping open between zero and full boost, and basically acts as a switch. On my 200sx there really was negligible lag using one of these so long as I was actually in an area of compressor efficiency. We now run a standalone ecu and it's even better, almost na response, and the pipe work is probably longer than on your MR2.
Got a vid btw?
I'm running a Profec E-01 so I was mucking about with the gain and psi start value. I could either make the boost come in really smooth or it was just come on too quick and hit boost cut. Think it may just be down to the turbo not being spooled up sufficiently as you suggested.
No videos as my camera decided not to play ball but here are a few pics.

wheels look good mate! nice to see something different on a 2!
On a seperate note, why have you got a number plate holder dangling of the front :p
That's the timing splitter. Made from dibond at 2am the previous morning. They line you up on the start line against the strut and once it cuts the beam your time starts. Then over the finish and the time stops once you cut the beam again. Will be putting on a vinyl numberplate I think. Had one on the mx5 and never got pulled so hopefully it will be ok.
I guess it has to be removed when on the road. I wouldn't fancy my chances against one of those if it were to hit me!
Interesting that you are using an EBC already... yes it must be that you're just off boost then, or the diaphragm is totally goosed - pull the vac line off and try to suck a vac on it to check.
From the sound of it your gear selector needs a bit of work - search for "ultimate shifter bushes" and consider new cables... it should slot down through the gears very easily, so if you are possibly avoiding dropping a cog because of the difficulty finding it, then that will cost you dearly.
Have you thought about getting a 2zz gearbox? You can either put the gear stacks into the MR2 box, or move the MR2 diff into the 2zz box along with the shifter mechanism, either way you get the same end result. 2zz box has much shorter ratios which will help with the boost... or a bit more left-field you could look at fitting a 5spd, since you're almost never going to need 6th on track and the weight reduction would probably find a bit of time for you..

How technology has advanced! That's very s8-) 8-) s8-)
Small update with some pics from my first event. Although my times weren't as quick as I'd like I did get the 8th fastest overall 60ft time with a 2.24 and a much higher top speed of 75mph compared to the mr2 turbo with 73 and the S2000 with 69mph.

Oh didn't realise the lock ups you were talking about where that bad. I wonder whether the amount of meat on the pads is different to the rest of them? Don't know if that would cause any issues.
Brand new yellow stuff pads all round. I took out the fuse for the ABS and it was fine after that. Pretty sure either a caliper is sticking or the ABS is screwed.
Sorry for the delay. Car has been in use as my daily for the past month as the BMW was in for some work. Now it's tucked away in the garage I thought I'd start work again. First things first. Found some carbon fibre vinyl from my old mx5, so I'd thought I'd try wrapping the vents s:D :D s:D

Not a bad job there mate!
How do you find the yellowstuff pads on track? Just running them on standard discs?
Yup, standard discs for now. I'm only doing sprints so max is 2 minutes running, so no fade, but they are a lot stronger than standard.
Hardtop bought and fitted s:D :D s:D
Carbon Bonnet Ordered. s:D :D s:D
Looking forward to the New Year!
So, errr, life and work got in the way a bit and I now have until till the 27th of this month to get the car ready for testing!
However, the good news is that I handed in my notice at work today. Never felt so free in all my life. Tis a tad strange to say the least.
Anyway, got an apexi powerfc with new version hand controller. Can anyone recommend a good tuner for PowerFcs?
Also, this arrived from Sweden s:D :D s:D
(http://section-1.co.uk/mr2/bonnet.jpg)
Bit of a long post for an update but here goes:
Finally sourced one drivers set of Rogue Seat Mounts, so along with a new Sparco Sprint bucket seat, harnesses and a 300mm Kode Steering wheel the cabin was almost complete.
Took the car to SOS Motorsport in Falkirk to fit and map my Apexi PowerFC. Unfortunately, as soon as boost was being delivered, heavy knock was being detected. This was traced down to the fact that the Mr2 only has 1 air intake temperature sensor telling the ecu the air temperature. However, the position of the intercooler isn't giving it any real airflow and it's suffering alot of heatsoak from the turbo, so the actual air intake temperatures post turbo is ALOT higher than the ecu is thinking, so it just knock back the timing in response. End result, I need to re-position existing intercooler or buy a new one that I can fit somewhere where the airflow is higher, or just bite the bullet and go for a chargecooler setup?
Regardless, my mapping session was only 3 days before my first event at Doune so I really had no time to remedy the situation properly. I did fit a temporary engine bay fan from my old Mk2 turbo, and at the advice of my tuner I turned off the boost controller, put the emange back in, and ran with the stock boost of 5.5psi for the event.
So on to the big day itself! If you've never heard of or seen Doune hillclimb I sugget you do a quick google. In my opinion it's the scariest hill to drive in the UK due to it's sheer width, or lack thereof, enclosed with wooden barriers on one side and a dry stone dyke on the other.
I was in class A8 which is for Road Marque Sports Cars. The majority of the cars in the class were Mx5s who also run a seperate championship alongside the Scottish one, but I also had 2 Mk2 Mr2 tubbys, an S2000 and a Noble M12 to compete with!
Practice 1 was abysmal after I forgot to adjust the coilovers from full soft setup for the road to the hard track setup I had been using previously. Practice 2 was much better and I posted a time much faster than I expected that left me leading the class going into the timed runs. After lunch the timed rans began and so did my problems. I didn't get a smooth getaway from the start line with some light clutch judder then after grabbing second and running it to the redline round the first bend and up and tried to grab third, it wasn't there. I pushed frantically, already conscious of the time and momentum I was loosing. I gave up and went for 4th hoping the torque would pull me up, it did, but by the end my time was some 3 seconds off my practice time and left me 5th in class.
In the pits my mechanic and I tried to bleed the clutch out and tried other various fixes but couldn't find any true adjustment in the clutch pedal or at the box. With the engine off the car goes through the gears no problem, but with the engine on and clutch down it crunches and grinds and won't go into third without a really heavy push, which makes us think the clutch isn't getting thrown out far enough or the syncros in the box are gone. Has the previous owner killed the box with too much power? Or has the pressure plate not been upgraded? As I've only got a receipt for a stage 3 clutch plate in my folder here. Any thoughts guys? Was thinking about changing to a 5 speed box anyway or slightly better ratios for sprint, but should I need to do change the clutch and pressure plate too? The clutch certainly ain't slipping once engaged. Any ideas appreciated.
I soldiered on into day 2 and took it easy for the practices so as to save the clutch/gearbox for the timed runs. Anyway, see below for the video of my second and fastest timed run of the weekend, complete with dodgy clutch/gearbo,. s:D :D s:D and I need to mount the camera higher somehow as it sits a bit too low.
[youtube:34f1bhu2]2ObXH8-j1w8[/youtube:34f1bhu2]
As you can see there is still lots of time to be made up there once I get everything sorted, but I still managed to win the class beating the Honda S2000 into second place by half a second s:D :D s:D

Great read and car mate s:) :) s:)
Box about to come out and inspect it and clutch/flywheel.
Might as well fit a proper intercooler while I'm at it.... s:twisted: :twisted: s:twisted:

Looks a beast.
Didnt fancy a charge cooler then.
That's chunky intercooler!
Quote from: "1979scotte"Looks a beast.

Bit too much extra weight and hassle with the pump and piping. Not to mention the price!
Clutch and flywheel finally came yesterday. So up to the garage today and fitted the Ultralightweight flywheel and Stage 4 6 puck clutch!

(http://section-1.co.uk/mr2/c2.jpg)
Pipes arrived for intercooler. 63mm out the intercooler down to 51mm on the turbo and intake. Also got rid of most of the cheap hose clips and got some big mikalor clips.
First offer up with the pipes and it was looking good s:D :D s:D
(http://section-1.co.uk/mr2/ic.jpg)
Before intercooler goes on. Dibond mounted to rear cross member and over the exhaust to stop heat transfer up into the intercooler. Also note mk2 mr2 turbo intercooler fan. I'm still awaiting my two 7inch spal fans so that will have to do for now.
(http://section-1.co.uk/mr2/ic1.jpg)
Intercooler on and ready for rear bumper to go back on.
(http://section-1.co.uk/mr2/ic3.jpg)
View from inside the engine bay looking back. As you can see it's a tight fit with only 2mm to spare!
(http://section-1.co.uk/mr2/ic2.jpg)
Anyway, did 100miles tonight of the 300 I'm meant to do with the clutch before giving it big licks. I'm booked into the dyno for 2pm tomorrow, so need to get another 200 miles done in the morning. Then hopefully racing this weekend!

How are you finding the Competition Clutch? Suitable for road use? How much did it cost?
Pretty harsh but still driveable. I'd hate to sit in traffic all day with it, and you do require larger calfs and a fair bit more revs from the get go, but my car is desgined for the track after all.
£320 I think for the stage 4, 6 puck.
Sounds like a proper sports car then?
My mate's second car was an MGC (1967, F plate). 3 litre competition car, basically (think MGB with such a huge lump in it that you struggled to see over the bonnet)
You used to have to twist your hips in such a way that you could put your weight behind you to push the clutch down.
And don't start me on the non-existent brakes. You folk with your modern brakes.....
Do you have to keep it road legal for the competition?
I do indeed. Have to bring with me proof of insurance, MOT and even tax! Had to get my phone out at the last event and go online to propve it was taxed! Some people really take the mick out of what is "road legal" though, but that's another story s:D :D s:D
As for MGs, I once drove my dad's rally prepped MGB GT. Not the V8, the woeful 1.8. That totally redefined the term "boat" for me s:D :D s:D

Yup, the MGBs were a bit like that. Different times etc.
I've always wondered about the whole race prep thing with Rally cars too. I mean, the rules state that there should be x hundred road cars built, but many teams make a car that's never actually sold, or if it is, it's to specialists etc.
It's not like you could have taken the Subaru Impreza to do your weekly shop, for instance..... (not to mention my Missus would moan about the bucket seats)
After contacting my good friend Chris @ Dynatune last night he informed me of a cancellation if I fancied finally getting the PowerFC installed and mapped.
The 30 mile run to Chris' completed my run in of the clutch and although I was worried something would fall apart or blow off on the dyno I needn't have worried.
Since the intercooler installation I'd disconnected the boost controller, so all my runs were done at the standard actuator pressure of 0.5bar for safety and accuracy.
We did a base run with the emanage blue (dotted line in graph below) and got 184hp at the hubs or 239hp flywheel (1.3 conversion ratio used by all the DynaHub guys like BLink).
A quick swap over onto the PowerFc saw instant gains, and after a good few hours mapping we hit a high of 221hp at the hubs or 287hp at the flywheel. However, you'll notice a spike in power at 6krpm and it not tailing off, this is due to the injectors going to 100% duty. So in order to keep everything in check, for safety reasons we've put a 6000rpm limit on he car at the moment till I can either getting a better fuel pump or add an adjustable fuel pressure regulator. Suggestions? s:D :D s:D
Anyway, I'm off to bed, I'm up in 7 hours to go racing for the weekend! s:D :D s:D

What was your peak torque dont want to fry the gearbox
Was at 239 when we checked and brought it down to 220.
Managed a 2nd place yesterday at Kames, then beat the Honda s2000 into 2nd place today for my 2nd class win of the season! s:D :D s:D

Pushing a bit too hard on my last timed run as I knew I had already won the class s:D :D s:D
Apologies for the poor video angle again. Will have something sorted for Fintray.
Thanks again to Chris Forbes @ #dynatune and everyone @ CHS Racing!

Looks very quick!!
Do you have the cross bar the roof mounted to in still? If so, the bracket for the roof latch makes a good camera mount point. It's where I shot the bulk of my Nurburgring footage from and it gives a nice view down the road.

Wheels or crank?
239 @ crank is fine.
My Sp240 does 220lb roughly.
By the graph I would say at the crank as it shows 183 on the graph
237 at crank if you x by 1.3 the figure a the hubs.

Update!
Post race inspection, and also whilst fitting a walbro, revealed the following:
(http://section-1.co.uk/mr2/v.jpg)
So I decided to give Fintray a miss and focus on getting proper airflow through the intercooler before getting the car remapped with the walbro.
......and also a turbo to block mount/stay to stop the cracking happening again. s:twisted: :twisted: s:twisted:
With the manifold off getting welded I renewed a few jubliee clips and replaced the turbo water hoses with braided ones.
With the mnaifold fixed and all of that bolted together, along with a bit of metal bar bolted between the turbo exhaust housing and the block, I set about the vents.
From the previous events I've done Ive found a lot of heatsoak whilst sitting waiting for my run. Even with fans blowing in the engine bay I'm essentially just blowing warm air at the intercoolers rather than cool air. I wanted to seperate off the rear intercooler boot section as a cold zone, and the engine bay as a hot zone, with air coming in from the side vents and exiting our the engine lid vents by way of a fan. The rear boot section I semi blocked off from the engine bay with a bit of dibond, then added a second bit of dibond underneath. On the second piece I drilled 2 100mm holes and fitted 2 heating vents upside down to catch the flow of air coming under the car. Coupled with some 100mm aluminium piping from B&Q to direct the air, and some banding, I had made a pretty impressive ghetto vent system for my intercooler. s8) 8) s8)
I also added an oil catch tank. I noticed after a few hard runs I was getting oil coming out of the top breather, so I've re directed it to the catch tank in the rear.
I took the car out for a quick blast and the difference was a very noticeable. s:D :D s:D The initial turbo/throttle lag I used to get is pretty much gone and she picks up so quickly now. The only downside.....as soon as hit approx 5k in 3rd gear the ECU started flashing at me. Injectors maxxed out. s:cry: :cry: s:cry:
Off to book in another rolling road session before Doune next month!
