A few pics and the in car from one of the 2:06 laps...








In Car: Haven't figured out a solution for heel-toe. Had a bad compound fracture as a kid, which makes it difficult without the peddles being almost on top of one another. Working on it...

 

Looking good!

 

That dash though

 

Ha....all the other failures left me with no time to pull the old wiring or hook the IQ3 up. In due time...

 

So what is your impression on the brooks wing after a few track events? Also are those the standard supports?

 

Build quality is very good. My guess is you will see in the magazine what my hatch looks like after the day (hint, it makes a lot of down force even at very little angle). It is definitely too much wing for the car right now, at its given power level and unfinished front aero. I plan to reinforce the back and figure out a way to get the angle I want in the next few weeks. No more track time until I do an open lapping day July 4 weekend.

 

was that the pro or the elite wing?

 

Elite.

 

I talked to them a bit about a chassis mount solution, but I haven't followed up with them...I'd recommend that route.

 

Damn so you went with the big one then. I can only imagine what your trunk skin must look like. What is the distance between the wing mounts?

 

28" maybe, I can't remember. I have it in all the measurements I sent them.

 

As an update, I've decided to bump up to TT2 after a few more events. The power is just a bit......boring in TT3 trim. It was going to cost about what the used SC kit cost just to go cams/valvetrain/oil pump and rod bolts in the DE to get up to full TT3 power. Just not worth it on the dollar to fun scale.

I'll update with the set-up info tonight.

 

Now I'm excited since that's where I plan to be once I return to the states and de-tune to make ST2/TT2.

 

New Parts:

Vortech V3 SCI
Unknown Treadstone IC
Fluidampr Crank Pulley
3.25" 928 Pulley
GTR Injectors (already have fuel pump in the car)
Uprev MAF if needed.

Reason for that pulley selection....the Fluidampr is larger than stock (but smaller than the ATI). The 3.25 matched with that crank pulley is actually a little more boost than a 3.12 on a stock crank pulley.

Target Power and Weight:

I have been running around 3030 this year and with the kit and a mostly full tank it should settle nicely around 3150, which is a good spot I think. Power will be around 405whp and hoping for 340wtq. Going to stay on 275's for the time being.

 

Why did you go with the V3 over a V2 for track use

 

Didn't put much thought into it really. That said, I still haven't used it on track.

Ran a new PB at Summit Point today before killing yet another drivers side axle boot (guessing early in the session because it killed off the axle from lack of lube). That is 4 this year. There is nothing contacting it. Guessing it could be heat related from the exhaust, which is somewhat close by.

 

What about differential temp? Mine was hot enough to boil water before I went with more oil volume and ducting.

 

I have a large Z1 diff housing, but my car only runs for 3-4 laps typically. So I don't even duct the brakes, etc. Biggest issue right now is it exploding the axle boots every couple of sessions. Going to try and do the wd40 tube vent and wrap the exhaust to see if it helps.

 

Another nice read. Good luck this year bud. Now I need to read your BSP prep setup.

I've been running TT2 with a single turbo setup for the past 2 years. I also typically run only 3-4 laps, but I added a differential and transmission fluid cooler just to keep temps down. It's likely overkill - but I wanted to extend the life of those parts of the car. I've also enclosed the bottom of the car with aluminum panels, but I've yet to run into the axle boot issues you're experiencing. The exhaust wrap may help, but I might consider adding cooling if that doesn't help.
