Just want to get some idea of just what some of you FI guys think this motor will handle....i have numerous diff opinions local...but just want to see what you guys think...Im running 7-8psi right now...another guy with an LS4 front mount was running meth and 9 psi -11psi but blew his ring lands...so i have some people local in my ear saying too much fuel and meth combo is what blew the rings....and then some saying it has to souley deal with power levels...
here are some specks..
2008 "LS4" 5.3L V8 ( LS4 )
Type: 5.3L Gen IV V8 Small Block
Displacement: 5328cc (325 ci)
Compression ratio: 10:1
Valve configuration: overhead valves (2 valves per cylinder)
Assembly site: St. Catharines, Ontario, Canada
Valve lifters: hydraulic roller
Firing order: 1 - 8 - 7 - 2 - 6 - 5 - 4 - 3
Bore x stroke: 96.0 x 92.0 mm
Fuel system: sequential fuel injection
Fuel Type: Premium Fuel recommended
Ignition System: Coil-near-plug
Its an LSx no matter! so wondering why he was blowing ringlands on 9-11....i am thinking good to 10psi....11 is pushing...even with meth...
