I've finally started my transmission project so of course I have to consult Pelican
I was originally planning to change 2nd, 3rd and 4th to 1.444, .963, and .667
This would put my speed at 7,000 rpm in each gear at: 56, 88, 132, 190 vs stock of 56, 97, 142, 202 (of course the car won't go 202 or even 190)
But now I'm leaning toward changing the R&P to 4.625 (8:37) and changing first gear to a 1.833
This would put speed at 7,000 rpm at 63, 89, 130, 185. So quite a bit taller 1st but right now I rev through 1st so fast that a bit taller should help and then a much tighter gap to 2nd so it should still be well into the boost after the 1-2 shift.
RPM at 75 mph would increase from 2,590 to 2,835 but that seems bearable.
Thoughts?
