As for turbos, power is power. 230whp @ 7800rpm is still ~155ft-lbs no matter where the work comes from. The disadvantage you're going to have with a turbo will obviously be lag, and the abundance of low-end torque on a FWD car which will cause serious traction issues. Claiming 200whp N/A is faster than 200whp turbo'd just isn't a correct generalization. For all we know extra torque in 1st gear or throughout other areas in the powerband can help makeup for the lag. A turbo'd SI is nearly guaranteed to have higher peak torque than N/A even if the HP is exactly the same. The two cars of course would have to have very different torque curves.

i surrender , were talking bout turbo ,supercharger is diff story, i can't win againts people who base there believes by reading other people's post or what they heard ,go get a turbo car and n/a car take them to the dyno make sure u turn down the turbo to match a n/a car numbers ,then run then both@ the track , then u tell me.. peak whp don't mean that much , good example is reflash , it will give u like what 3-4whp @ the peak, won't u agree that a car that have a reflash is faster??than the car with the same peak whp??
