All the stock twin dynos I've seen have max power at ~5600 rpm.

that's where my power maxes, but that's on 91 octane and 16lbs of boost, I imagine mine would peak int he 5600 range if I ran 100 octane and let the boost max out

i know this is an old thread and im sorry if this sounds stupid but, ive seen this 5600 nuber before, so this means on the 1/4 mile if i shift at 5600 i should go faster than redlining it???
thanks

no because you wiull fall out of your power band if you shift too early. Ive had good success with shifting at around 63-65. Hope this helps

My car at BPU peaked for HP at 5400 rpm with a hi-flo cat. But the power was very similar up to 6500 rpm, after which it dropped off slightly near redline. I would shift at 6600 rpm on the tach, which is about 6300-6400 actual if you measure it on the dyno (more accurate since it comes from the direct signal, the stock tach typically lags 200-300 rpm behind).

Plenty of usable power at that rpm, and it puts you at a good rpm range after each shift. My T61 peaks at 6700 actual on the dyno, but I rev to 7500 rpm on the tach (~7300 rpm actual), same story as above. :D
