does it work well on N/A cars?, ive been thinking about it, but dont know if its worth it.......
Obviously it will gain more on boosted cars, but it really depends on your specific engine I suppose. Higher compression engines will benefit more than lower.
When did you switch over to E85? Is that a new development?
I switched about 3 months or so ago. A friend of mine in Florida showed some great results and I was looking for a better alternative than race gas or octane boosters such as Torco. I am not a big fan of what Torco does to your engine nor was I wanting to spend big $$$ per gallon on race gas. I built my car for street duty and car shows. But I always like getting the most out of my combo.
I also don't like the inconsistencies in 93 Octane pump gas and always trying to stay right at the limit of detonation as far as boost and timing.
So I did some research and changed over. There were no cars around me running E85 so I was the guinea pig If you will. After I retuned my car and a few other local friends saw what timing and boost I was able to run, they switched over as well.
A good friend of mine who has an 04 Cobra almost identical to my set up was the first of my friends to switch over. He was currently running Sunoco GT 260 (100 Octane) race gas because a station about 30 minutes North of him had it at he pump for $5.99 per gallon. He was hessitant to switch because his car was already making good power and he figured why mess up a good thing. After he switched, he was kicking himself for not switching sooner as was I.
Here is his combo which is basically the same as mine.
STOCK block, stock heads, stock cams, stock manifolds, catted X
2.3
whipple gen 2 @ 21-22 psi 2.75 upper only (just a little whipple), NGK Br7efs gapped@ .026
Twin GT pumps, GT 500 BAP, dual FPDMs, stock rails, -8 feed, 80 ln inj
24 degrees timing (yes it continues to gain more beyond 23 degrees)
A/F ratio pre-cats 10.9 - 11.3 (On a Gasoline Scale Wideband)
Here is his STD Dyno Sheet after E85.

Here is his comparison between 100 Octane Sunoco GT 260 and E85.

In the midrange he picked up more than 100 RWHP nd RWTQ.
Not bad for a stock Cobra with a upper only pulley small 2.3 Whipple!
Since his dyno we cleaned up his A/F a little more and hedecided to take 1 degree of timing out. It should be the same power wise with those adjustments.
I haven't had a chance to dyno my car yet because of my clutch but I plan to as soon as I put a new one in. Our cars have always performed basically the same with the mods and we are both running the same set ups.
Hope this helps a little.
Needless to say I am VERY HAPPY I made the switch and I'm sure more people will switch once they realize the benefits.
