So with E85 becoming more prevalent, who has switched and what are your mods? Is it worth buying injectors, fuel pump, and getting a tune for the added hp? Dynos and tech info wanted/appreciated

b.r.i.a.n.

this has been covered a dozen times. do a search.

So lets compose a comprehensive thread with dynos and setups for NA cars

Did you get the other kids at school to do your homework for you?

Someone has mentioned on here that e85 is not worth it when you're n/a

Actually yes, yes I did.

To be fair, there's not a plethora of information/threads on running E85 on an NA S2000 engine.

I have been running E85 in my NA S2000 for a few months now. My current mods are intake, header, test pipe, 75mm single exhaust. Switching to E85 was pretty cheap for me as I did not factor the AEM EMS 2 into it as I would have purchased if running gas as well, and I am able to tune myself. To be able to run E85, I installed some WRX/STi 565cc injectors that I got from a friend and some PnP clips I bought from Treadstone Performance. I also picked up some new seals which were like $5 (friend worked at Honda). I've converted a lot of Subaru's to E85 and also my boosted Taurus SHO when I still had it, but this was the first time I've bothered with it on an NA car.

My purpose for going E85 was for helping keep the car cooler on track days, especially 100+F days. The only thing I've really done for tuning it for power is clean up/smooth out the timing (to include a timing adder when in VTEC) and lowered VTEC. I'm running higher timing in some areas due to lowered VTEC and making the curve smoother, but overall timing is no more and I won't really look at doing anything with that until I get time on the dyno, which is looking to be Spring.

I can say that my cat-less exhaust smells a lot better with the top down. E85 is everywhere in Nebraska and it's cheap, despite the lowered mileage. With that said, there really isn't much power to be had with E85 in NA form on these motors. There is some piece of mind for purposes like mine and it clean up carbon deposits, but that's about the extent of it.

Topic has been covered a bunch of times like Brian said. I've been on e85 for 2.5+ years and also used it in my cammed prelude back in early '09. When my S had an aem cai/plm header/custom 3" exhaust it picked up a lot of midrange and torque when I switched over to e85.

This dyno is my before and after on e85 and I also swapped out the intake. The intake was basically just a shortened AEM cai.
