Those are pretty badass numbers regardless.TurboSaleen#163 said:I have a 97 4.6 with a TDC turbo kit.It put at the wheels 443rwhp and 496rwtq with nothing done to the motor.Im worried if I do anything to the motor like PI swap or even a TB I might risk blowing up the 4.6.Considering the car put out around 180-190 to the wheels.That is a big HP difference.Im told I am pretty much at the max now without blowing the motor.
