What is a safe rev limit (come inside for more info) I am putting in a small blower cam on 918 springs with chromemoly hardened pushrods soon and eventually will be getting blown (i love saying that) anyways, all the other internals are stock, what is a safe rev limit that i should run? thanks!
With swapping rod bolts I've seen people safely run between 6800 and 7200. Mine is set @ 7100 with my WOT shifts @ 6900. But I guess every engine is different? Just my .02

6300 is a "SAFE" area and above that probability of failure increases.

My limiter is set at 6800, and my shift light is set to light up at 6400 so that i'm shifting around 6500-6600.
My cam pulls all the way to 6800, but I don't see the point in running the car that high when I'm racing b/c of the added risk of failure.

You really don't actually believe that? Do you?

I have mine set @ 6700 and bounce off it a lot and feel pretty safe about it. Anything higher I would start to worry. I have friends with stock bottom ends set @ 7050 shifting @6900 seems a little high to me but everyone has a different opinion on this...... Without any facts to support it, I personally feel 6600-6700 is the max safe limit...

wow that seems kind of low, but here is another question, is it pointless to move the limiter up if u are making all of your power below that? say u peak out and start droppin HP around 5500, does raising the limiter do ANYTHING for u?
