Pure simplicity. I tune cars daily. Even as a tuner i would rather run e85 over any gasoline and methanol injection. Especially for anything under 350hp per litre.

My answer doesn't change. Eat your heart out.

 

Eat my heart out. Oh man don't make the thread go sower all ready. Keep it professional.

From a tuner stand-point E85 is much better. It allows the tuner a HUGE amount of safety because of E85's lack of pre-detonation and because of the amount that is adversely injected its cooling ability. Fuel w/ meth injection is more efficient, and for the volume of water/meth injected, has even better cooling properties.

From a power standpoint this is where the chemistry of things is going to start to bog it down. Really E85 is just taking the dummy out of a meth injection set-up. It is basically pre-mixed for you in a alcohol to gas ratio. That is nice in that nothing can go wrong with the ratio of mixture or the injection set-up, like it can on a meth/water injection set-up.

But like we have learned you still need to have X amount of combustible fuel to make X amount of power, so to do this you just inject twice as much to get back to the amount of combustible fuel you need to make X amount of power.

All I am trying to say is that there is more then one way to skin a cat. I would say that both are very comparable. Both have there +'s and -'s.

If you stated at first that from a tuning standpoint its a "landslide" with E85, I would agree. But from a overall set-up, or power, or whatever....I don't think its the killing you describe.

Are you running 21 psi in the middle or all the way to redline?

 

21 all the way to redline

 

Not to be bashing or anything but why are you only making 381 lbft of peak tq for only 1k rpm and that's not until 7400 rpm?

Mine is making roughly 580 whp at 25 psi on 105 motor octane race gas and roughly 380 lbft of tq on average (that's not the peak tq) from 4800 - 8700 rpm with my 60-1 turbo.

Are you guys using a huge turbo or something?

 

Bigger turbo, different manifold, different fuel. Probably a host of other reasons, too. What are your numbers with pump gas?

 

we are using gt40 since that was only turbo we had at the shop. it is laggy because it has 1.19 a/r LOL i have gt42r at the shop so i might change it later. its weird but gt42 has less lag than gt40(even with smaller housing) For now i have to leave it alone since it belongs to my wife!

 

Interesting...overkill for a daily driver on the street, but good numbers anyway.

Sucks about your lack of torque w/ 600+whp. I'm making 330wtq and only 450whp on 93 oct.

2.0L and a GT40 daily driver....hmm, why don't you just slap on a GT50 and let us know how it goes.

 

hahaha you mean gt55 right
