I am doing the calculation to make each gear shift on redline 8K, drop RPMs to 5500 RPM in a sense that everytime you shift the car is climbing the revs similarly to a ferrari 458 and you are never away from the 6-8K RPM range where the S54 (boosted) is in its most brutal power delivery zone.

Is what i said interesting to anyone over here?

Please note that making 1st gear with a lower drive ratio and 2nd gear with a slightly higher drive ratio will bring those 2 gears closer and synchro effort drastically down which means that you might be able to shift 1st-2nd drastically faster
I guess, as a non drag racing-designed car, I don't really see the point of the fast 1->2 shift. Others may drive it differently though.
