I was thinking the other day that I would like to see someone try a N/A DOHC motor with turbos and E85. IIRC its 10:1 compression. I seem to remember people ran up to 12psi w/meth on TT conversions. I would think that the knock suppression of E85 would be of particular interest to people with TT converted cars and the original engine.
Anyone done this? How much boost would you be able to run with E85 and that high compression? 15psi+?

If you would like to see it done, you should give it a try.
And yes, NA is 10:1 and yes you could probably run 15psi on E85 and 10:1
Nobody has done it, but e85 should allow you to run more boost before you get knock.
The only problem I see is this: Methanol is going to require about 35% more fuel, and you're going to want to use a standalone to tune. That's a pretty sizeable investment for a base/SL.
what size injectors would you guys suggest running if someone where to go e85 with stock 10:1? and about how much boost will the stock n/a bottom end hold reliably?
the only reason i would throw the rb26 in my car would be so i could throw a bunch of gt-r stickers on it and not be a complete dumbass like half the mustang owners out here...a 3000gt-r would be pretty badass if you could actually pull it off

I might if I didn't already have a corn-fed money pit. I'm just throwing the idea out there.

True, you would need something to tune with. But dsmlink/ecmlink is being adapted for the 3S right? That, and a beefy fuel system, is all you would need in addition. From my experience, ethanol only requires around 25% more fuel.
Drop in some huge injectors, 800cc+, and a rewired 255HP and you should have plenty of fuel for 15-20psi. I'm not familiar with injector requirements for the 6g72, so take that with a grain of salt, but with dsmlink or a standalone there is little reason to get anything small when the price difference is marginal.
I was looking into doin this myself with my tt conversion on my 10:1 which im starting to put the turbos on and everything but i was all into it till i relized there isnt alot of gas stations around here yet with e85 but it will take around 30% better flowso i would throw some 550 injectors with a 255 fuel pump hotwired and something to watch your knock and control ur fuel. i would be goin this way if there where a place close i could get e85. Once i find a place nearby selling e85 i will be doin this but for now im going pump and meth injection.
I'd actually like to see someone do this on a built 10:1 VR-4 someday. I've actually been toying with the idea for quite some time, but since the closest E85 station is about 200 miles from where I live, not worth it.

VR4's are not 10:1, nor should they be. It defeats the purpose of being able to upgrade turbos and run a lot more boost.

hmmm the only benefit to this is that you would have a torque monster in a 10:1 vr4. you would have alot more low end power, and with forged internals and 15gs, you would probably max the setup out. It would be a monster out of the hole, and pull great through the powerband...but with 8.5 compression you could run 16gs and e85 and or go as big as your please.
the 10:1 would limit the car too much

SL-TT and E85?
