ive been reading shifting at 5400-5500 will net better numbers than spinning it up to 6000 but I wouldnt know, its worth a try though.

Lets say for instance:

first gear ratio is 3.38:1 and second gear is 2.00:1

If you shift at 6250 rpms @ 260 hp:
3.38 * 260 hp = 878.8 affective HP.

Now what rpm will you be at when you shift @ 6250?:
2.00/3.38 = .5917
6250 * .5917 = 3698 rpms

The powercurve at 3698 is 210hp
210hp * 2.00= 420 Affective HP.

You dropping your power in HALF if you shift even at 6250. If the crank can handle it id say shift closer to a mach ones redline but i'm not sure if it will handle that high of rpms without a forged crank.

my fastsest run was 13.71 @99.10. the car weighed 3775 with me in it (240). i cut a 1.943 sixty foot. these cars hook like crazy, 4000 rpm launch on the stock tires. the weather was terrible, very humid , and the car still has only 400 miles on it. when these babies get broken in , low 13s shouldnt be a problem. i did learn one thing , the car runs better short shifting 3rd and going thru the traps in 4th.
