Best RPM range to stay in for acceleration

My rev limiter is at 6,450rpm right now and when I red line it I up shift at about 4100rpm which is about 500rpm after the peak torque... is it better to shift sooner and upshift to 3500 (peak torque) or is it better to take it all the way through each gear? And when I say better I mean fastest acceleration possible...

Re: Best RPM range to stay in for acceleration

I shift at 5000 to 5200 rpms. From what i understand that is best for v6's as well.

Re: Best RPM range to stay in for acceleration

You want to shift more at peak horsepower rather than peak torque. Peak horsepower for the V6 is at 5250 RPM. So I would say just past that, like about 5300 RPM.

Re: Best RPM range to stay in for acceleration

Yea peak horse power and redline are two different things. You should NEVER take your car to the actual redline unless its peak power is there... which it shouldnt be.

The only time you should ever go past your peak power is if you want the rpms to be a little higher in the next gear~ but its a trade off.

Peak hp for 99-00 v6's is 5250 and for 01-04 is 5500 rpms (due to IMRC intake vales added). Shift there.

Do NOT go to 6400 rpms, i have no idea how you even got there as the car cuts off at 6,000 rpms from the factory, valve float can take place at 6200rpms on the v6's so do NOT go that high.

I think the 08 peaks at 5250 also, so revving past that doesn't help acceleration? I can only get to 6400 because I raised the rev limiter... I'll take it back to stock today, don't want to abuse the thing...

Actually the best way to see when you should be shifting is have your car dyno'd and with those results you'll be able to see where your peak HP and TQ is. TQ is pretty much irrelavent, but it'll still be nice to see it.
