Also, why not run AWD dyno also?

Will run it on a linked AWD dyno soon

Incorrect. The F90 is considerably quicker...

I am surprised the 60-130 is quicker in RWD. And I am wondering about the 60-130 times. It's a 127-129 MPH trapping car.

Also the 1:1 gear for the F90 is 6th - which was 587 WHP - even at 10% drive train loss (some say the newer cars are more efficient) - that is still 652 HP. 690 at 15%.

Traction isn't an issue at stock power levels so naturally one can expect it to be faster in RWD due to less drivetrain loss. The 60-130 times shown are right in line for 127-129mph traps.

Question on the 60-130:

0-60 is at least 3.2, go through the 1/4 and it is at least 11.1 to 11.2 - at 127-129 MPH according to the magazines.

Did you get your times from a dig/low MPH start - or at 60 MPH and then hit it? Or was this gained via the dyno run? I would submit that if it was a part of the dyno run, that the 60-130 MPH runs will be significantly quicker on the street. With a 127-129 MPH trap - my guess is at least in the high 7's.

It's about finding the sweet spot between gearing and momentum. It's best to get going in fourth gear (to avoid a second shift) around 50mph and end at the top of fifth.

But I did expect a quicker 60-130 time based on the car's trap speed. It's not slow by any means (it's a four door luxury sedan for crying out loud let's put things into perspective here)

Off topic: the list above showing a C6 Z06 with a 7.8 60-130mph time is pretty insane, my best stock C6Z is 8.2 guess I don't have the driver mod lol

I fully expect to get walked by a stock F90 M5 on the freeway in a stock C6Z, from a dig the AWD M5 will be multiple zip codes ahead by the time I hit 100mph on street surface. Just wondering how the 7.8x C6Z 60-130 time above was measured and how that compares to the 60-130mph time for the F90 M5 here.

Correct me if I'm wrong, but doesn't a stock C6Z trap around 127mph? If you're running 60-130 in 8.2 seconds as well, isn't it impressive for a car that's 4,000+lbs to be just a tenth slower?
