The TPC kit is strong and linear to redline. You can also look at the dyno graphs and see what I'm talking about. If you look at my videos posted you can see me running down GT3s and my wife over taking and creeping away from an Audi R8 V10. This was on a closed course.

The major differences are a TPC Carrera is lighter then the factory turbo but the factory turbo has better gearing on the top end. 6 one way/ 1/2 dozen the other.

If you plan on doing a lot of dig races or hit the drag strip enough the AWD of the factory car will be better but anything else they will be the same IMHO.
I mostly track and having the power through the rpm range is perfect for that. I am sick of getting smoked on the straights by the gt3's and turbo's. I think this is the option for me.

despite of what gets told here from what i saw and from people i personally know it looks like most m96/m97 engines do not last very long on a track with any FI solution on them. so i would only do that if i would be comfortable with reserves left to buy a new motor if modded one will blow. again, you just need to be realistic about it all and not to expect miracles. it may last almost as long as non-FI, it also may have some embedded issues that will be intensified with more stress from FI and it will kill it.
and who cares what was the actual reason after it blows, right? if that stuff would be so easy and robust - no one would be paying for gt3 motors, but, alas, it is all connected. you get FI, put on slicks, get 2 times cornering force amount than before and in the mid corner at high bank you run out of oil as it all was pushed on a side and engine dies. as simple as that.
and every FI builder will tell with a straight face - no, it was not our unit fault, it is totally unrelated . but who cares.

imho if you do come to the point where stock motor is not enough for your rebuilt suspension - despite all the seemable attractiveness of FI route best way to go is to bite a bullet and buy a dedicated track car - either newer gt3 based version or older car like 'rs america' or anything else with a proper cage, suspension tuned to slicks, car gets on a trailer and gives you much less headache overall.
there is only one track worth car with FI solution - GT2. it was possible to get one this summer, some are still for sale.

and who cares how fast most of those turbos can go on a straight if you will get back on their tail after several corners usually.

your right to a point. I run track evevnts out side of DE and my friends have Lambo SL, track prep corvettes, Scud's and I keep up with them inside or they keep up with me but once on the straight forget it, its like I am standing still. I need more power other wise the car is setup nice and I run on NT'1's shaved flat. I wish I had the money for a gt3 RS but its not in the cards for now.

look at this :
http://forums.rennlist.com/rennforum...a-on-ebay.html

a hell of a car for $25K. if it is still available, folks say it still is.

PS. what events do you run, btw? just curious, as i start to do more and more 'outside PCA' events too.

It's up to you. I had zero issues on the track. There are tons of turbo Caymens on the track with no issues. There have been very few F/I 996/997s that have had issues but usually its IMS or RMS. If the IMS/RMS is bad on the car it will go with or without F/I. It is a known issue. Heck, I've seen 20K mile GT3s with leaking RMS. . . You are only running 4-5psi which is nothing these days and truly not enough to even warrant an intercooler but the systems still come with one as added ins. People don't give the M97 as much credit as it deserves.

if anybody wants to track m97 a lot - read this

and similar info, it is not difficult to find. i do not say it is not possible to track this motor, it is just a requirement to know its weak sides and do some preventive actions.

It was a "timed" practice for a race and the driver botched a shift just before this happened.

If you look hard enough you can find anything bad about anything.

When you have cars and mod and race you kind of know that there is always a possibility of something happening. But then again, I've seen good ole fashion stock cars take a dump driving down the highway . . .

Have fun with your car and don't live in fear

Good thought, but a word of caution to anyone considering doing this...it doesn't ALWAYS go as planned. After TPC Turbo'ing my car I now have a car that pulls great, and if you ignore the CEL's and the beeping, it will run right to red line. However I cannot track it any longer - the CEL's are caused by misfires, which on the track results in dropping into a "limp mode" after about 15 minutes of running hard. Still fun for the street but not exactly what you'd be looking for in a track car. After almost 2 years and literally months in their shop TPC is still scratching their head and can't figure it out. Hit and miss - take the chance, but recognize that the kit isn't fool proof on every car.

Reps for bring forth a concern and an issue on the turbo. The shops all say no issues. I would be concerned if my car was in the shop that much!
