Scawt's 996 Turbo Track Toy Build
#31
Nice list! Have you looked into a Cup style rear wing for the car? Makes a tremendous difference. Since you have MoTec, I would use the Motec DHB fuel controller to run your fuel pump on an on demand basis. Its far superior to the factory system with built in safeties and you can bypass the OEM relay all together. Very simple hook up and relatively cheap at around $600 if I recall. Really works well, drastically reduces fuel temperatures and allows you to up the fuel flow with a larger pump for the new turbos. I was running out of fuel on my K16s with the OEM pump and injectors. The pump was OK in a straight line but would be insufficient in high G corners due to the constraint of the OEM fuel system. Pump output would also decrease once fuel got hot which made the problem worse. If you don't have a way to control it, fuel heating becomes an issue on these cars once the fuel cooler is removed.
Regarding the fuel, I told Rothsport/Markski to keep it below 500whp per your previous posts. I'm still on stock rods and need to keep the torque low anyways until I go the 3.8 route in a year or two. The fuel upgrades will definitely be apparent then. In the meantime, I'll check out the MoTec fuel controller.
On a side note, I made custom door pulls and working on handles after the car comes back from Rothsport.

Yep, no stiffening but not needed now
Thanks! I wasn't planning on the cup wing this year but couldn't pass on your deal.

Thanks! Cup doors are on the list but at the very end since I just modified the stock doors and the cup doors are costly to replace.

This is the link below to the DHB controller. We tie it to rpm, boost, and engine load and it works great.

Thanks guys! The next part of the build is going to take a while so I'll probably be out for the rest of the year. Paint shop and Rothsport are currently backed up for a while so the 996 is hanging out with some old friends
The good news is that the parts pile keeps growing!
Getty decklid, carbon wing and endplates (Thanks Powdrhound!)
997GT3 rear ducting and undertrays

We have progress..
Motor and trans was pulled a couple weeks ago at Rothsport
I was bored during the waiting period, so I did some porting at home and had the turbo pieces coated in black by a local ceramic coating company.
While the motor is out; it was rolled over to the paint shop for the Getty decklid to be painted, final coats on the roof and the new Joe Toth spiltter. Can't wait for the cup wing to go on top!

It's actually pretty cheap for the GT3/2 steel roof from the factory and I just ordered it from my local dealer for ~$500 (99650350100GRV). You'll also need the expensive headliner but I don't need it for a track car.

Wow, amazing build!
A great thread I have totally missed because only browsing the GT3 forum and Racing forums here.
Nice to see more people getting on with the 996TT track crack pipe....
Could you tell about the weight savings with the dash? Obviously with Motec etc difficult to say.
One thing you might know well but wanted juts to point out, you will have soon issues with the gearbox (aka. the 3rd gear, the stock 3rd gear just can't take the beating with your torque, maybe it will handle one season, but be prepared for update! One tip here, after doing basic rebuilds for my box (because of 3rd gear) for too many times, I accidentally found a nice cheap new 997TT box, and am very happy - never hear 997TT folks talking about 3rd gear problems and the shorter gearing of 997TT box compensates for my larger rear tire and now have basically stock gearing). Sure installing the GT2RS stuff there is best, but by buying a 997TT box I was back on track in no time.
Steve, don't understand why people tell CF roof is dangerous, I was the first guy to come and save my good buddy after he rolled his (similar type of) 996 badly with CF roof, the roof helped there a lot, he only had a roll bar in the car. And please have a look at all the BMW M models that have CF roof directly from the factory.
So, for the roof conversion, I went with Carbon roof, was more expensive (500 vs. 1500 or something), saved 5+ kilos more vs. steel roof, I wanted the maximum saving with the hassle, and looks so nice!
Scawt, I am almost on the same boat with you, have a street legal 996TT with +200hp and -150kg vs. stock car, car has interior and air con etc so I call it the "poor man's GT2 RS" with a 996 Clubsport full cage. No trailering in Europe, just driving to and from the track.
Good luck with the car!! These cars are expensive to run but SO fast if you consider the total (ehh...initial) investment
