Default 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.

Nice. How big is that single nozzle? I have twin 10gph ones in mine. Thinking I could go even bigger when I go down to 5.3. I'm ls1 stock with cam now around 800ish rwhp. But a 5.3 is waiting when it pukes on me.
What power adder? Psi? Timing?

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.

My map is only a 2bar. I just watch my afrs and let it eat. Everyone I talk to says my fuel (dual walbros, fic1000cc injectors) will run out around 1000rwhp. So like you I'll test limits eventually.

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+.
