Stock LS3 Fuel System Enough? Slowly putting together a new engine for my 2011 Camaro that will see 50/50 time on the road and HPDE/Mile events.
Engine is a ERL 427 (~11.5:1 comp). Cam not yet spec'd but will be on the milder side as far as lobe design to support broad torque and sustained higher rpms. Heads undecided but looking at three choices at the moment depending on what I can afford (Ported TFS GENX 255, Ported LS3 by Frankenstein, Ported LS3 by WCCH). Will be pushing stock weight Camaro through TR6060 and LPE 4.10 read diff. The goal is 550 RWHP with broad flat torque curve running on 91 octane. Probably run two tunes, one for daily driving and one more aggressive for the track when I can bump the octane to support. I'll be running dual wide-bands for tuning and monitoring.
So will the stock fuel system support this setup? Seen guys claiming it does and guys claiming it doesn't. I suspect if it does I am on the edge. Deatsch Werks calculator suggests I am good as far as injectors.
Required Fuel Injector Static Flow Rate @43.5 PSI
480 cc/min 46 lbs/hr
Next concern is can the stock fuel pump keep up? Once I start tuning it should become evident real quick where I stand but trying to stay a step ahead without spending more money unnecessarily. Thanks.
