[QUOTE="GNBRETT, post: 15823588, member: 111882"] u definitely need an X amount of octane to run that kinda number. it can be done with methanol for sure. straight 93 is definitely pushing it past 750hp on pump gas unless u got some huge CI motor then u can make 1500+ hp on pump 93. but most tuners won't tune a 5.4 or Coyote setup past 750 hp without methanol just not enough CI/compression. I come from the Turbo Buick world where routinely run 30 lbs of boost with methanol on 93 octane. without the alky no where near that on 93. there are quite a bit of variables when determining if ur gonna make 800+ hp on pump gas. Cams, heads, valve train, type of forced induction ur running, timing and of course a stick car is gonna put down more HP to the wheels on the dyno then an auto where u lose 12-15% on average. u can run all the boost u want as long as its not detonating. My combo will make a completely different HP number on pump 93 then yours will because I'm running a Turbo but I plan on making over 800 hp on straight 93 octane but I will be using Methanol as insurance just not fuel. but seems like u got quite a set-up for sure but 850 hp aint happening without some extra octane from methanol imo.
