Again I agree completely, 400 HP does not sound like much compared to all the magazine, trailer and dyno queen, shop bragging rights, etc, cars out there but it is a damm fast car in a Supra. In a tC is is just an accident waiting to happen, and going to be fairly unreliable and hard to maintain at that.
My Matrix had all the proper supporting mods from seats to LSD to wide race tires and 250 WHP was a dang quick car at 2,600 lbs(what I had it down to) 300WHP is what our goal is for the tC and it will be plenty fast enough for us.
I was at a shop a couple of weeks ago and they were talking about their shop Supra with 1,200WHP and said they drive it on the street, sure, I imagine all the time, NOT!
Power is great when it can be used which requires a whole car concept. Our tC will be setup properly first, most done now, the rest of the parts are here waiting for us to have some time to intall them, before we turbo the car.
Brakes, suspension, clucth, LSD, wheels and tires, seats, weight control, etc, etc, etc. Then we will go for the power we want to run, with all the mods now and with stock power it would supprise you how much more capable it is up in the mountains than a totally stock car, we would run circles around one.
Set your priorities straight, build a whole car and go for real world usable and reliable power, you will have far more fun, be far safer, be able to actually drive it more and spend less!
