Stage 4 Turbo Setup

aaronjb · July 20, 2011, 15:30

I like the way things are mounted from the brace - that plus everything being coated makes it all look very 'factory'.. aside from the catch can s;)

s;) and, ironically, the factory alarm sensor!

AmeR · July 20, 2011, 16:04

That looks really tidy and stock!! I will definitely be wanting a nosey in the metal at CAE s:lol: :lol: s:lol:

andywood · July 21, 2011, 20:18

Very nice!!
Got me thinking that I should wrap my manifold now (may help to keep engine bay temps down), what heat wrap is that??

You'd have to ask Matt I'm afraid. He sourced it for me.

That looks awesome !!! Must be some experience to have that much power in a "2". s:scared: :scared: s:scared:

It comes from Trident Racing Supplies at Silverstone Circuit

I think I need some of that as well...I am noticing a lot of heat at the back of the car. Is it expensive?

muffdan · August 9, 2011, 20:04

Not sure how much it cost now. It certainly wasn't enough for me to remember so I guess it didn't break the bank! s:)

Well quick update. Those from CAE will be aware that I had a misfire a few days before the event, which I tracked down to a dodgy coil pack. I had a couple of spares so I switched the faulty one out and all was good.

Ordered a new wideband kit and wired that up. The ECU is now running from a closed loop AFR target table again which has seemed to have helped fuel consumption. AFRs look good throughout the rev range.

This weekend I developed another misfire. Another coil pack I figured! Wrong! I loose connection on an injector sorted and now all is well again in that department. There is an exhaust blow but I can't see where it's coming from. It's not loud enough to worry me but I'll keep an ear out for it and see if it gets any worse.

Now that the engine's run in, I got to play with it on a local airfield trackday last Friday. The car is performed very well. Inlet temperatures are much better. Where I was seeing an increase on 40 degrees over ambient within 20 seconds at Christmas, it now takes a minute or so to get that warm. It returns to ambient much quicker too. Acceleration times on the day were:

0..60 at 3.8 seconds
60..100 at 4.6 seconds

This is still running on the old map. I haven't upped the rev limit yet or increased the boost. These figures are significantly faster than it was at the start of the year (despite the warmer weather) when it was achieving a 0..60 of 4.2 seconds and 0..100 of 5.3 seconds. I guess the bent valves coupled with the high inlet temperatures were seriously hurting it.

All in all, very pleased with it and hopefully it'll stay working for a while now! Once the lotus has been reworked I'll get the MR2 mapped up to 8k and a dyno print out.

Want one! Congrats J. Hope it keeps on going now!! Sounds like you have irradicated a lot of issues and it's running a lot sweeter!! s8)

I was trying to think of a good response and that about covers it, so +1

Meah!........ok I suppose s:wink: :wink: s:wink:

ChrisGB · August 10, 2011, 10:58

That is well into supercar territory! Must be a blast to drive. How is traction on the Contis? The 0 _60 time indicates it is good s:D

s:D

muffdan · August 10, 2011, 12:07

Yes, traction with the conti's (in the dry) is absolutely fine. Much better than the T1R's were. I only run 60% boost in 1st gear and there's no wheel spin (unless you try for it with super high revs). Nailing it out of a corner in second gear is fine too although I don't have the courage to WOT it in that situation!

In the wet it lights up the rears in 4th gear. Not fun.

The close ratio 3rd/4th gear set I have definitely helps the acceleration times as red line in 4th is not much north of 100. I dragged from 60 to 100 just using 4th in ~5.5 seconds give or take a couple of tenths. Understandably when its put in 5th, there's an exagerated feeling of power loss. I think I might change the 5th gear ratio for the Lotus version too but keep 6th as it is for cruising.

I-ll wait till I know your in top gear when we do our next continental run then nail it and watch you eat my dust s:lol: :lol: s:lol:

Had a full brake overhaul. Refurbed callipers, new discs/pads and fluid change. I went with the black diamond grooved and drilled discs again but switched from the Carbotech XP8 pads to Yellow Stuff. The braking performance is no where near that of the XP8s on both initial bite and more critically on brake fade. When on the track rubber, I think they'll be found unacceptable and I believe I'll have to get myself a set of track pads to switch in/out when I swap the track wheels on/off. I'm not sure I'll stick with yellow stuff at the next change for every day use. However, they are MUCH cheaper and don't have the annoying constant squeal I use to have from the XP8s though. I'll see how they go. Perhaps I'll forget how good the XP8s were and get comfortable with the Yellow Stuffs!

And since yesterday morning, she is no more!

Bloody hell !! Hope your ok mate? What happened..? s:(

AmeR · May 18, 2012, 08:43

Holy crap on a cracker!! Hope you're ok!?

Wabbitkilla · May 18, 2012, 08:47

Quite a tumble there Jason, glad you got out ok .. even if a bit sore.
This doesn't seem like a good year for the turbo fraternity.

FGrob · May 18, 2012, 08:55

It's really shocking to see this, glad you're OK, I still get that shoulder looked at as the results of that type in injury can be life changing (speaking from experience of a work colleague). It was on the road then - just yourself???

Yes Nic it would appear we are losing turbo's quicker than they can be produced - that's two of the top output machines gone, plus the second green one in as many weeks.

s:shock: :shock: s:shock: Strewth!! That looks like it was a biggie! Lucky to walk away from that one.
Loads of money gone into that, great shame,but main thing is that you're okay. s;)
