The amount of power you can extract from a motor is in direct proportion to the thickness of your billfold
- and what type of power you're looking for - max horsepower (very high RPM - everything lightened) gives great numbers but's typically miserable to drive - max torque (lower RPM, higher compression) - no where near as impressive on paper - but shoves you back into the seat in an impressive way -
Define the power you want - then start checking out what others have hit - and for how much - on a normally aspirated VR -
Then start writing checks!
