Heh Heh. Wanna watch a E55 rev like an SLR! VID

Maybe I'm asking too much.

Debating if iwant to mess with my tcu since my car takes a beating the way it is now and I wouldnt want to put more stress on the tranny.
revving to 7k would also help big time in the 1/4 mile as 3rd gear would shift in a better spot in the power band.
The Best of Mercedes & AMG
Revving at 6,500, our stock gearing will fall like this:
1st to 2nd = 3,900rpm@51
2nd to 3rd = 4,200rpm@84
3rd to 4th = 4,600rpm@131
4th to 5th = 5,400rpm@185
Revving at 7,000, it would look like this:
1st to 2nd = 4,300rpm@55
2nd to 3rd = 4,500rpm@91
3rd to 4th = 5,000rpm@141
4th to 5th = 5,800rpm@199
If I use my dyno:

I can say that the car will indeed be quicker as it would have better average power, assuming it doesn't fall flat on it's face after 6500rpm.
Now, if we rev to 7K and install a 2.82 it would look like this:
1st to 2nd = 4,300rpm@52
2nd to 3rd = 4,500rpm@85
3rd to 4th = 5,000rpm@133
4th to 5th = 5,800rpm@187
Takes better advantage of the powerband AND faster acceleration via shorter gearing. Win - Win!!
2nd gear is even worse than 3rd.

6500rpm w/ 3.27FD w/ 255-50-16:
1st to 2nd = 3900rpm@42mph
2nd to 3rd = 4200rpm@68mph
3rd to 4th = 4600rpm@106mph
4th to 5th = 5400rpm@150mph
6500rpm w/ 3.55FD w/ 255-50-16:
1st to 2nd = 3900rpm@38mph
2nd to 3rd = 4200rpm@63mph
3rd to 4th = 4600rpm@98mph
4th to 5th = 5400rpm@138mph
Those gear ratios are kinda insane imo...it would spin 2nd gear like crazy.
