I disagree.
My Stealth has been 'upgraded' more than modified. It has the factory spec turbos instead of the North American downgrades, higher boost and a 3rd injections system with replacement exhaust, but it had 7psi stock and I'ver merely upgraded the boost levels to what's probably the same as what the GTR has (14). It'll go to 19, but with race gas - which I don't have. Race shocks instead of the stock electronic suspension to improve the performance. Since I like a stiff ride I don't need the 'bandaid' ECS to soften the bumps on the road.
Sounds like youre saying that the Viper is a slow car on the track with all it's torque and 3.08 gearing?
Yes, the Viper keeps 'upping the bar' for supercar performance, doesn't it? It's probably why the ZR1, the 19(?) Enzos and Porsches GT3 were designed.
You gotta love the Viper. I wonder if anyone will design a car specifically to beat the GTR? Guess not ... since there's so many cars that already kick its ass. Maybe a new AWD Supra? As you said, "Everyone is making 500 hp+ now and wanting to be called a supercar." The GTR doesn't make the wannabe 500+hp.
The GTR amy be a great DD, like my Stealth is for me, but I bought a sc Viper because a Z06 passed me about 100mph when I raced it. That'll never happen again.

You are only making my point more valid. If you increase boost on a stock turbo system, there are bound to be some other areas that need addressing, most stock BOV's,DV's turbo hoses, wastegates etc are designed for the stock power, so when you go and up the boost, something will start to fail or not operate as designed and the hp application will be affected, this goes for ALL turbo cars, most have wastegates that will crack open prematurely bleeding boost, which kills torque, slows throttle response and messes up the curve. So chances are your mods made the hp curve worse than it was stock even though you increased the hp.
Not only that but like I said, that is EXTRA OLD technology.
How does what I said translate to a Viper being slow on the track? Harder to drive doesnt mean slow. GT3's are hard to drive too, because it's hard to keep them in the powerband there in lying the challenge with high revs and low torque. F1 cars for example have 800 hp and 200+ torque. More torque is needed on closed wheel cars to accelerate the mass and because there is more reliance on mechanical grip rather than aero grip, but still low torque is the preffered method.
Actually you are wrong in two areas. I am not going to go into detail but do know turbo HP is different than NA HP. For one it takes time for boost to take effect. NA power is always there. Also even though as technology improves, yes its less of an issue, but still an issue, heatsoak from forced indiction effects engine power eventually whether it is after 5 or 10 laps, point is it does effect the power compared to NA. That is all I am going to say. I have a turbo Car and know the difference, and am not just talking about a low HP Turbo car. How well would a nascar turbo car fair compared to a NA nascar car? No contest. And the point is Dodge has been able to make the best track NA track car to prove this. We will ultimately see when the ZR1 hits the track, but I am not talking the 1/4, but the road course.
I know NA hp is different. My comment was soley directed at people that say Turbo and FI is cheating. That doesnt make any sense. Heatsoak can be dealt with, and good ones dont soak badly, and in fact NA motors can heat soak just as bad and power is limited with NA, whereas Turbo power is relatively unlimited. Yes NA has better throttle response, but on a road course where the goal is to maintain high rpm's it's not much of an issue for a good turbo system. Both have there advantages and disadvantages. Many racing sanctions penalize turbo's because it's easy to cheat by dialing boost up and down, but that doesnt mean it's not as formidable as NA.
Dodge has a V10, they dont need Turbo's, but when CAFE starts kicking in ********, you should expect to see one, turbo motors are cleaner and more efficient, while still making the power of big bore NA motors. Put similar downforce numbers on a ZR-1 and the ACR would have it's hands full to say the least, so a direct comparison isnt exactly being made because the ACR has a FAR FAR superior aero dynamic advantage. I personally dont like superchargers because they overheat more than anything and the belt issues are the worst, so you wont get much arguement there. But turbos have graced F1, Indy, Lemans, FIA, ALMS and several other forms of racing, but there are just more parts to break, more weight added to the car, and more ways to cheat which is why it's not more common. There is no better or worse, Turbo and NA are both great for racing.
