4.08 or 3.90 gear questions...

Not quite. I changed it over to the 3.9 gearset (5% increase)

Like it much better for all around driving. 1'st gear is out of RPM in 2 sec or less at full throttle. The 4.08's ran out of RPM even faster! It's no fun bouncing off the rev limiter that quickly.

Now that I've used the 3.9 gears for awhile, it seems normal for me to shift to second almost immediately after accelerating from a stop.

The rev matching (SRM) is a lot closer with the 3.9's vs the 4.08's.

In retrospect, I would have left the 3.7 gearset in with the supercharger as I'm always loosing traction in the first two gears at full throttle.

But in 3'rd and 4'th gears and the SC the acceleration is fantastic ...... right wheee!?
