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.

 

You can usually get about 450 out of 1000s, and target lambda will be basically the same as gas.

 

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.

 

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

 

man that's it 400hp??

 

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.

 

I put down 430 on 91 octane. Im tuning on E85 in about 2 weeks. I'll post my results

 

How do you lower your BSFC to make more power?

 

Increase the efficiency of your engine.

 

Tony - 450hp with the ID1000s?

 

I have a stock short block b18c1 with rc 1000's in it on a t3/66 turbonetics @24psi on E85 pushing 498/322

the only thing in the head is saupertech springs other than that pretty much OEM

 

Yup, made 450whp on E85 multiple times on my dyno with ID1000's.

 

BUT IM FIXING TO BE BUILT AGAIN AND NEED SOME ID2K'S LOL

IM IN LOVE WITH E85 MYSELF EBCAUSE ITS AWSOME TO HIT THE PUMP THEN THE TRACK AND NOT EVEN USE A 1/4 TANK OF FUEL OUT OF 6-10 PASSES ON A TEST AND TUNE NIGHT HEHE

 

I put down 428 on e85 with 880cc precision injectors

 

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

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)

 

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?

 

we did 467whp on rc 1000cc injectors on a mustang dyno

 

5 hundred and change with intank and inline walbro & ID1000's. 70psi base

 

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)

 

i knoew my buddy made 525hp and 404 tq with his h22 set up

 

520whp on E85 (Dynapack)
1000cc
B18C
GT35R

 

We made 630hp with 1000cc injectors, a single walbro and an sc61. Not saying it's safe but it was done

 

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.

 

^ with e85 ? i seem to see most tuners stop around 450whp with 1000s and a single walbro255 whats the duty on them ?

 

623whp S2000, ID1000, E85, walbro + bosch pumps, 97% duty
