my 370z vs. my 2007 335 coupe...

OK. My wife and I raced about 4 times tonight. She in the BMW and me in the Z. On average the BMW took the Z by 1.5 cars at 60 mph. I would guess that the Z will get a bit faster with break in but no way at this altitude will match the BMW. I plan on a exhaust and k&n and see what that does.

You are one lucky guy for having a wife like that!

Not sure how bad alttitue affects NA cars but 1.5 cars is probably like .2 to .4 sec behind BMW.

Looks like NA has about 3% additional degradation in performance as compare to FI cars at 5000ft.
