how much hp can 1000cc support with e85
Planning to tune my car with e85 and just wondering how much hp I can get off this gas. C16 is making a bigger hole in my pocket. Knowing how badly this economy is now I just want to try something cheap and affordable for the time being. Also what is the target WOt a/f for e85 compare to gas.

Re: how much hp can 1000cc support with e85
they will feed as much as 350~400whp without going too hard on them
We usually tune cars @ E85 in brazil..
Lambda factors will be arround 0.82 to 0.76 on boost.

Re: how much hp can 1000cc support with e85
The real question is what your BSFC is going to be..... I'll guess .8
1000cc = 95 lb/hr (@ 45 psi @ 100% duty)
95 x 4 = 380 lb/hr
380 x .85 = 323 lb/hr (@ 85% duty)
323/.8 = 403.75 hp
1000cc = 95 lb/hr (@ 45 psi @ 100% duty)
95 x 4 = 380 lb/hr
380 x .85 = 323 lb/hr (@ 85% duty)
323/.8 = 403.75 hp

That's it with a BSFC of .8. A decent turbo honda will be closer to .70-.75 on E85 though. Usually 450ish is what we see.

Re: how much hp can 1000cc support with e85
To everyone saying "that's it?" - that was all calculated out at 45 psi. Any serious car would be running another 45 psi of fuel pressure on top of that. Then the numbers would look like this:
95 lb/hr @ 45 psi = 134 lb/hr @ 90 psi
134 x .85 = 114 lb/hr x 4 = 456 lb/hr
456/.8 = 570 hp (@ 90 psi base @ 85% duty)
and if Tony says .7
456/.7 = 651 hp (@ 90 psi base @ 85% duty)

I always guess 'rich'. In my line of work, that's the safest way. Goin' on 9 years and haven't blown anything up yet. lol

Stupid question:
If you have a walbro 255 and 1000cc injectors, will that change your stock fuel pressure? Or do you have to buy a new FPR to make more than 45psi?

Re: how much hp can 1000cc support with e85
If anyone knows what duty cycle they were at, we can calculate the BSFC.
For example:
at 70 psi, they flow 118 lb/hr. at 85% duty (hypothetically), that would be 100 lb/hr x 4 = 400/515hp = .78 BSFC (of course that's not 100% accurate because we really need engine dyno results, but we're close)

Re: how much hp can 1000cc support with e85
Yeah my friends motor made 622 on 1000, and a walbro 255. He was running stock fuel lines, fuel rail and FPR. It was with a 35R also at 26 PSI. We def were not shooting for that much HP, so needless to say we were are surprised that day. On reguler pump gas at 19PSI he made 490 and thats how he drove it for a year.
