5.3 power limits on pump 93/meth
Just like the title says. What's the most power achievable on these engines on pump 93 and a ton of meth. Forged, not forged, small turbo, big turbo, supercharged, heads, intakes, doesn't matter. Anything goes just as long as its power made on pump 93/meth with a 5.3 displacement. NOT e85!!!
And also if you were trying to achieve the most power using these combined fuels on a 5.3, how would you build the engine.

Cool. I use 100% meth. M1 VP fuels brand. That's good power on 16 psi. My s475 took 17 psi and 14* timing to hit 755. My AFR is super fat. I live on the safe side. Yours gives me hope because I wanna upgrade my turbo to something better and I'd like to push pump gas and meth as far as I can within reason on the upcoming 5.3.

yea im happy it makes more then anyone thought it could. little turbos doing work. It made 800/800 at 5100 rpm. but we had to remap a table in the map to allow more air. Its fixed now and we will take it till the fuel runs out. Or the map is maxed 21.7lbs Ill have a forged 5.3 soon so im not to worrried. Ill run 15lbs most days anyway.
Mines also tuned really safe. these numbers were after we backed like 2* out to be safe.

Well obviously lol. Stock assembly may hold 1000 or may let go at 500rwhp. With stock parts its always a gamble but more are on the winning end than the loosing it seems like. I never thought a factory high mile ls1 with a cam swap would see 800+ and still run perfect. But just curious the limits of the combined fuels in such small ci platforms. You see 408,427,434,441,454 lsx stuff doing crazy pump numbers. All 1100+ some endless money cases 1400+.
