Yea its all cool and all, but why would someone dyno a 6spd car or 7sp auto with use of 4th gear? Wont this give false reading because lower gears get more power?

 

I think the standard is 4th gear, ive gone to a few dynos and most everyone dynoed my car in 4th and one time in 5th.

 

should be done in 5th

 

Actually incorrect. 5th gear is 1:1 on the Z and is the proper gear. But the car's speed limiter will get hit so it won't read the upper rpms. At least this is true on the 350z. The 370z depending where the speed limiter is might be the same or different. 4th gear will show more optimistic numbers over 5th gear which will show more accurate numbers.

 

So what power is 350z making in 4th gear?

 

A brand new one was recently dynoed on a mustang dyno in 4th 265whp 5th 275whp. Hit the 150MPH in 5th, stopped the dyno, not sure what the rpm's were.

EDIT just found the vid. Im the guy standing on the side of the car.
