I mean, when you get that big, you have all kinds of factors to deal with. Because you taking the car kinda out of street performance as you would know. If your even looking at those turbo's size's then money is no object. I mean the lag is way up there due to the size. So your pushing the rev limiter up passe the 8k mark. Which means the motor needs to be built, because of the much added stress. But your talking 700+rwhp which means your kicking NASCAR's Ass now....lol.
