Then there is longevity and driveability. You may establish a 250 CHP NA or 800 HP turbo motor but that does not necessarily mean Will probably be greatest suited in your targets. The NA will likely be peaky, the turbo will be laggy. each will sacrifice a lot of dependability for that efficiency. For Many of us a 180 WHP NA or 250 WHP turbo will be a lot greater.
