Built LS rev limit

Just curious as to if theres a "safer" way to rev this LS to 8500RPM ( yes it is built and will handle this abuse) besides adding more fuel in the last column of the scalar. Obviously the stock LS maps do not support the higher revs and I do not believe you can change them to do so but I am not completely sure. Any help or opinions on this guy's?

Re: Built LS rev limit

why not just open up a gsr bin and disable the vtack/knock/pressure?

Re: Built LS rev limit

Even with aftermarket springs ls's aren't really good for that high of rpm's.. but in crome you can change the rpm's to what you want.

Re: Built LS rev limit

Oh I agree, I wouldn't rev an LS that high at all without expecting a rockerarm to fly out of the valve cover. But, I warned the owner and he wants an 8500 RPM rev limit so I have to make it happen

I'll look into Crome because I know I could use rev-tools to enhance the rev range but I'm not sure if that only applies to the high cam tables.
