Here're two dyno charts for a couple of E85 fuel powered car.

This is a Rx7 w/ a single turbo. Mild street port, GT40R turbo running approx 19-20psi (boost creep from 16psi). Racing beat dual exhaust (major restriction). It's nothing fancy since I'm still keeping timing conservative. This is about 500rwhp with 8% difference between dynojet and my mustang dyno number




06 EVO 9 tuned w/ opensource. FP red turbo, 1000cc injectors, 280/272 cam. running 26psi. Don't ask me what that dip is at 6500rpm, its repeatable and doesn't appeared to be engine timing related. It might be Mivec timing need optimize for E85 fuel. This is about 480awhp.



So far, I like E85 other than the fact it takes a huge amount of fuel to run properly but you can almost tune it like race fuel.

Just for ***** and giggles. Here's another dyno chart on a twin turbo camaro I tuned on pump gas using Accell DFI. It's a 427cu in block running twin T70 turbos at 10psi on pump gas. Tire shake limited me from running higher boost and rpm.

 

 

Don't you owe people money?

 

How is the idle using e85 vs gas?

 

and what does that have to do with e85??

does he owe u money??

 

search carbon fiber widebody kit and his name if you want a good laugh.

 

Um. NO and NO. I don't owe anyone money personally nor I find anything on the search you mentioned below

 

I think start up is a little rougher but it idles fine once it stablize.

 

Lookin awesome Steve. I'll get with you soon about figuring out a date to come back out to stl.....

 

I does start up rough, I just started playing with e85 in my first gen turbo, have to work on my idle, seems a little rougher than gas....

 

Sorry pluto, not you I was referring to.

 

steve I messed with the idle some more,

it fired right up this morning felt like the temp was in high 30s,

I got it to idle very smooth 900-1000rpm thats with microtech wich is not that great for idle, 1000cc primaries and street port,

I am very happy,

I know we were running out of time the other day
so need to strap it back to work on the staging hick up

also when I got home u know how the throtle was sticking
it was actulay not opening all the way, after messing with it I had to
tight the cable almost 1/2 inch more so felt little faster after that

who knows will c

 

Do it...

 

Hey Steve

Great to see you doing some E85 tuning It's a great fuel, i used it last year. If it's difficult to start when warm, u just double the priming map on hot compeard to when it's cold. It seams like the rotary engine likes more fuel on E85 when it's warm. Might have something to do with the fact that E85 vapors at a lower temp then normal fuel.

I had so much trouble getting it to start when warm, that i tried everything. But after doubling the fuel i had no problems. And we managed 530rwhp at 21 psi with a T04Z and Brige Port 13b, and duty cycle at 98% :P

It needs so m uch more fuel then normal gas.

Bdw how's it in texas these days? Im missing the heat

JT

 

Hey JT!! good to hear from you. I think the starting issue was related to cold start, it starts fine when completely warm. I just feel it is a little rough when cold.
As for the Texas heat, I won't know right now since I'm in the Carribean for the next two weeks but masquitos are killing me down here...

 

Ahh problems when it's cold hehe. Vell if it's below freezing it will get hard to start, as E85 get's harder and harder to start the colder is it.

U will just need to play with the cranking map. And the E85 will make the car rough when cold, due to the amount of fuel beeing poured into the engine. And the fact that E85 ignites more hard when it is cold. So pre heating the E85 always helps alot.

Here in norway during the winter they can't get the rally cars to start if they try it outside. They need to either warm up the fuel, or keep the cars inside :P

Hmm carribean sounds good. Im in england now, getting my 4 rotor installed. We will start tomorrow on the process of getting it in the car

JT

 

I used 4ms to start when cranking when warm. When the temperature dropped below 0 deg F, I had to increase the fuel to 12ms when cranking to get her to start. With E70-E85 I have no issues starting the car in cold weather, and I have 1680 cc primaries, it just takes a LOT more fuel to get it started. You guys in Norway may be different since we only see a few deg below 0 deg F.

agreed Ant, My car starts right up, idles smooth even after 3 weeks of sitting dead cold.. whether its E70 or E100 play with the tune pluto its off.
