DirtyDave: The sprocket turns at the same rpm as the input shaft with a 5 speed and 6 speed in final gear. Engine rpm in the 07 six speed is lower because of an obscenely large primary comp sprocket. The standard 6 speed is not an overdrive.

I have an Ultama 6 speed and 6th gear is overdrive. I believe the person starting this had an Evo. All Evo after market 6 Speeds have overdrive gears as 6th.

 

DirtyDave: Now I understand.

True, they are 1-1 in 5th (06 & prior)& 6th (07-08), however the final drive (and) primary ratios have been changed in the new 6 spd's. There is a significant drop in eng rpm (400 aprox) from an 07-08 6 sp compared to an 06 & prior 5 sp. Eg; 70 mph = 2600(aprox) rpm in 6th.
