I like these threads as they let me spit ball so to speak and it helps me learn.

I am starting to think that instead of trying to replace 2 or 3 gears in a 930 or putting in a shortened G50, just putting in a lower R&P might be a cost favorable way toward a significant improvement. (Nothing new, others have been doing for years. Just know I better understand what is happening.)

If a stock 930 is as follows:

2nd, 2700rpm at 53 mph
3rd, 1900 at 94 mph
4th 1800 at 137mph
red line at 197 mph.

To something like this:

Full boost if at 3500rpm would move from 27mph to 21.5mph.

If full boost is then dropped to 3000rpm it would come in at about 18mph.
