Dynos are a useful indicator of performance gained, but by no means are they the end all be all of performance. I thought everyone knew that one.

Secondly, peak numbers only tell a fraction of the story. The area under the curve, and getting that power to the ground effectively matter a lot more. So a car with more power can still lose to a car with less power. Everything else being equal, then yes the car with ONLY 18 extra bhp will still win.

Does the drive train lose power? Yes. Does 18bhp matter to some people? Without a doubt it does. If 18hp wasn't that much of a gain then why do some people bother getting an intake or a test pipe or whatever other mod that ONLY gets them a few rwhp.

It still baffles me to no end, why does everyone think that owning a Nismo means you are not allowed to change any part ever?
