Without revving the engine to 8k looks like your shifts are on point.
You'll never fall back to peak torque since your peak torque is all the way at 6200-6300 lol.

Hmmmmm, or maybe 7500...

You will typically want to take a Centri car as high as it'll go, assuming it doesn't start dropping boost.

If it'll safely handle 7500+, 05stroker, you need to be taking it there. On a curve like yours, assuming I am correct that the run was stopped at about 6900....you should be taking it much further. I would bet you would gain 2 tenths by taking it to atleast 7300+ in every gear.

It will "safely" handle the power as much as any other well built 3v. I have faith in the build. As for the rpm in every gear that is what I am after here. Sounds like I am on track. I would LOVE a 7500 in each gear pass!

I'm not pro by any means but I concur... take her to the top and bang them quick and hard. I try to pull the next gear at about 6k knowing that by the time I do she is about 6500ish...

"listen to the motor she will tell you when it's time"

Good thread. It's all about the details.

Been shifting at 7700 As of the last year and a bit

Nothing wrong with 6800 rpms on the stock stuff. Just dont go any more. Many have been there.

 

[fdjizm]

Been to 7k a few times, was puckering up though but no issues. lol

I cant wait till 7200 in first and 2nd!
