We could find that out soon... Haven't decided yet! TurboTweak has a FlexFuel capable setup

Yes it is! The colder temp equals more density. Just like having a ported everything. When alcohol burns colder than gas its like going to the track at 5 degrees.

Yeah The key is the boost in the GN is adjusted by the GN computer. Add a alcohol sensor to pinwheel the boost way up to 25psi via chipset and alcohol will give you another 100 to 125 hp over 91 oct. Adj injectors more!

We already know E85 is liquid gold for boosted applications. We are primarily talking about NA.

An n/a engine designed for alcohol that can run on gas? Yeah right through away 14:1 compression, more timing, more flow and less weight(exhaust/cats)daily driver.

It's not like nitrous, but it's not insignificant either.
Btw, the results were not remotely close to 10% on that test you're referring. With the engine tuned to 100 octane, it had a 1% gain in horsepower (540 to 546) and a 3% gain in torque (509 to 524) with E85. E85 will gain power, but the gains are not significant without tuning accordingly.

Well, that is technically true. But yeah, using E85 in a n/a engine tuned to, lets say 93 octane, nothing remarkable nor noticeable is going to happen, without tuning it accordingly of course.

It's only not remarkable because the ones that think it's not is a spoiled bunch of bitches that think everything has to pick up 50+hp

This unremarkable 10-20hp gain will likely put my bolt on ls6 over 450whp with changes in tow.

You get a 10-20whp gain using E85 in lieu of gasoline without any tuning at all? Simply only switching the fuel?

Now, read VERY carefully. Switching to E85 and tuning accordingly to get 10-20whp gain is significant. Without tuning, the gains won't be no where near that, it'll be much less (aka, nothing remarkable).

Just like when you did rockers/springs, but you think they are no big deal for a bolt in.

You can't run E85 without tuning. It's a totally different fuel source. You have to up the amount of fuel burned by a lot because of all the oxygen in it for those big gains. Flex fuel works nice.

Even crazier is FTW oxygenated ethanol. 5.br0's run it in their lil ole daily drivers because it picks up 30-35 RWHP over pump gas on a stock NA engine.

What does his rocker dyno sheet trap?

Does he have a dyno sheet for E85?

I think Hio did rockers and one other mod and gained 4rwhp.

You will eat cat poop for the way you talk about bolt ons!

Yes sir. But technically you can run E85 without tuning and the engine will run just fine, even without flex fuel. It's just not a good idea for that exact reason, but of course will show negative effects if ran for prolonged periods without the proper fuel system setup and tune.
