500 on pump has been done. More then 500 on pump has been done. My buddies civic with a built gsr is making 630 on pump stock compression. I know it's not an f motor but there's videos of that had been done.

I'm sure there's a lot of s2k over 500 on pump gas but they are done with built bottom end. i haven't heard of one with stock bottom end doing this. if so they are definitely pushing the limits

Ive hit 80% injector with 255 + id 1000s at 13psi gt3076r .If my boost controler had not fecked up i would have hit 460whp .With the old greddy emu i was at 18psi 420whp stock with no problems apart from a over safe tune,hence new tunner .

your compairing a B series to a F series. That doesn't really work. They don't have the same parts and are not built with the same material. I have yet to see a stock block F series pushing out more than 500 on pump. E85 as mentioned is a different story.

I was shooting for 500 on pump with my stock motor with a 6266. I only made 481 with Id1k's and and a walbro 255. Ive switched to a 340 pump now and wired it up with relay. Going to shoot for 500 on pump, and whatever i can get switching to the shell Urt gas also.

It also depends on how hard the tuner is willing to push. I know for a lot of tuners in my area they aren't willing to push very high and compromise reliability/longevity of the motor. The higher the boost the more heat and higher chance of detination. This is what I have gathered after talking to a few tuners on here as to why its hard to reach 500 or past 500 on pump.

Your right, Mase told me that also. Thats why im changed my setup some.

But mase still tuned phils gt3582 with the first mase kit to 602whp 22psi reving to 10.2 stock engine on pump so its possible ,how long it would have lasted who knows.

That's insane. Is that with stock HG or 3mm? 93 pump gas?
