Re: 6mt Split Case Swap

Someone can/should check my math:

Stock SVX Tire 225/60/16 =812 revs per mile

80 mph = 64960 revs/hour = 1082.67 rev/minute

1082.67 * 4.11 diff = 4449 rev/minute at diff
4449 * 6th gear @ .695 = 3092 RPM @ 80 MPH (Non-turbo trans)
4449 * 6th gear @ .666 = 2963 RPM @ 80 MPH (Turbo Trans)

Either of those is good with me...

The Best ratio in the HD 6MT is .707 x (3.900 /1.1) which gets 2713 RPM @ 80 MPH
which would also be fine.

I have a daily commute on 80MPH roads, so the final ratio is important for me.
