Gains from E85 (ethanol) on an N/A bolt on 370Z

Flex fuel is one of the great things that our government developed and released to the public. Too bad not many companies (especially the outer lying stations) took the opportunity...........

This is what my tuner did like. Beat the hell out of it on the dyno and i quote "not a bit, nothing, zero sign of any detonation at all!" I dont know how sensitive he made my knock sensor but for a track car this makes me feel good. Again i tested this batch of fuel at E80.

I was thinking about cjm stage 1 kit and ID 750 injecrors with aeromotive fuel pump 340. Overkill?

For N/A? Yes. But if your panning a FI build then you'll already have your fuel system in place

What he said

Elmo370z · 09-19-2015, 12:45 PM

Ok. Just gtr injectors and fuel pump? I still plan on doing the high rev build. I just dont want to go back and buy more parts rather have it in place. Thats why i thought of doing the id 750 and cjm stage 1.

lj909 · 09-19-2015, 01:08 PM

If your going to stay N/A and do a full build with ethanol, then raise your compression ratio as well to take better advantage of the ethanol.

I think if 1slowz had raised his c/r and did ethanol he might have come very close or breached 400whp

Injectors only here, seems fine. Op used nothing

That will prob happen in 2-3 years once i get the money saved up for ipp stage 2 short block

Which is exactly why my engine build is planned around 14:1 compression - that alone should provide a healthy torque increase and the cams will shift the torque up the rev-range and improve HP

Lol im trying to keep it street0-able

Whatever u take from this dont fall into the "e85 doesnt work crowd" because ud be egregiously wrong. Unfortunately your setup just isn't working with e85. No one has ever made anything but less power with e85 on the same timing as gas. Thats just how it works. Our platforms tuning software suppliers need to step it up imho.

So if thats correct im not sure why you got more with fuel trimming only. Clearly i need ecutek! Turner can only run 28* same as gas.

My OP clearly demonstrated I gained power with the fuel alone running pump gas timing. If you can't at least see those gains on UpRev you've got another problem.

Tried what?

uprev vs ecutek on e85... i would have thought you would be able to make gains with uprev too. however, as syno tested it on his and he lost power. i got in contact with a tuner here in atlanta that claims i would make power even with uprev.

njobe89 · 09-21-2015, 07:15 AM

also, is there a definite answer on will going e85 do anything to the car in the long run.

Megan370z · 09-21-2015, 07:31 AM

Im pretty sure I remember seen a guy on here running with E85 and showed gain which was with Uprev last year.
There is an issue somewhere in the tuning because Uprev can advance it to 32 at high load/RPM

I run E85 on cars as old as the early 90's, haven't had a problem.

Screw UpRev and their garbage software. I bought their dealer package as well and it's the biggest pile of crap you can imagine. I won't disgrace my Z with that ****, lol.
