I was referring to FI N54 and NA S65 (hence the tread title). I don't like going off topic (meaning other FI cars vs other NA cars).

A blanket statement like NA>FI is pretty dumb. The 370Z is NA and that car overheats on track.
IIRC the stock 370Z does not have an oil cooler?

Also I'm not saying you're fast or slow, but it's also driver defendant.

Not sure what your times are at Button Willow or how hot it was when you were there

At SOW this past weekend it was 105, pretty freaking damn hot.
