Read this in another thread a minute ago and it got me searching and wondering.

Is 7200rpm near safe with stock rod bolts?

My friends Z06 w/Torquer v.3 is tuned at like 6.5k rpms because the tuner said he didn't trust the stock bottom end on anything more than that. And his car only has 8k original miles.

My car is getting ready to be tuned by the same guy, my engine has 94k on the bottom end, but completely fresh top end. I am running the Torquer v.2 112lsa. Am I gonna be safe at 6.5k rpms or even possibly safely go higher than that?

What do you experts say???

No expert here, what year is your car?? It is kinda a crapshoot if it will last or not. Some people have issues and others don't. I would say to be on the safe side to put some rod bolts in and be done with it. I put in katech rod bolts.

We typically set rev limiters on stock bottom end tunes are 6800 RPM. Haven't had a failure to date.

Awesome Jon thank you so much. My car is a 2004 GTO. I would've put the katech bolts in but this was actually a very cheap budget build. Most of the stuff & money to do this was given to me. The only thing I bought was cam & spring kit & gaskets. I did all the work myself & my friend.

I would stick with 6800 too, that's where I've been running at for years on the stock bottom. IMHO at 7000 and up you're on borrowed time.

usmonaro

Thanks guys. Pretty sure I'm gonna be set at 6800. You guys say I'm safe there?

I've got ~150 passes, 8 years and 30K miles that say you should be.

agreed...

6800 is pushing it, but as long as when your saying limiter, you mean the actual rev limiter. some people i talk to when they say limiter, thats where they are shifting at.

if i were on a stock 98 short block, i would shift around 6200 and move the limiter to 6800.

even then on stock rod bolts...its a gamble, but i beleive a safe gamble.

Yeah, I would assume with a 6800 limiter you would be shifting around 6600.

depends on if you have an aftermarket tach or not. i noticed in these cars, above 6000 the tachs get lazy.

usmonaro

Are you talking about ls cars in general or specifically the GTO. My friends Z06 doesn't seem to have any problems with the tach above 6k.

i have no experience with the Goat and the Z i beleive has a 6500 factory redline.
