Safe maximum RPM for my setup?
Safe maximum RPM for my setup? Hello,
I am wondering what max RPM you guys would run on my setup. I was shooting for 7k but wouldn't mind opinions.
L33 w/ stock bottom end at 74k
-Katech Rod Bolts
-Katech oil pump
-LS7 Lifters
-BTR Pushrods
799 heads w/
-BTR dual platinum springs and tool steel retainers
-Manley stainless valves, maybe 1-5grams heavier than stock each
-224/228 .581/.571 112+4
-MLS Headgaskets
- Subtracted .026" from combo of milling and thinner HG
LS6 Intake
-CNC'd LS1 Cable TB
Longtubes 1-3/4"
Where would you spin to?

Run in on the dyno untill it stops making power then set your rev limiter there. No need to spin it higher than it needs to. My car stops making power at 6,800 rpms, thats where the limiter is set and I shift at 6,500.
Thanks for the replies. I agree and was planning on limiting revs right after power falls off.
I was more concerned with what RPM the bottom and upper end components would be stable to. Am I going to be safe pulling up to 6.8-7k if the power is there?
I had spec'd the cam to fall off higher up and sacrifice some low end torque to help deliver the power to the ground more easily.

Yep, see what it does on the dyno and make your shift points using that data. As long as everything was put together right, no need to be scared at all to spin it as high as it needs to go.
