I wouldn't put less than 850cc on an E85 Evo. We are using 1650cc and twin pumps on our own car.

With Evos you are usually looking at fuel pump, injectors, and tune. The tune being the key in the mixture. The Evos seem to be a lot more particular even with small upgrades that you wouldn't seem to think matter.
Running E85 would make the car LEANER, not richer.
Let's be sure the correct information is being provided here.
Headstuds should be used in any circumstance where high cylinder pressures are used such as 28-34psi which the stock turbo is perfectly capable of producing.
TTP
Why would you upgrade the headstuds on a stock turbo motor? Is that something that you suggest to your customers? There is no need to do that on a stock turbo. They are needed upwards of around 500hp... As far as I am aware they do help... just like pistons and rings or any other supporting mod would, but not needed. Hence why I made the comment "on a stock turbo?" And in this same thread you give conflicting info and you are then gonna post some crap about "Let's be sure the correct information is being provided here." I am stressing the importance of a tune thats all. On a stock turbo 1000's-1200's should suffice for e85 and they have for me just fine along with countless others.

Pistons and rods do not help either.
A 500whp car on 20psi would not need headstuds.
A 400whp stock turbo car on 30psi would want to have headstuds due to higher cylinder pressure.

K, This car is EDM though, does that matter? we get E85 straight out of the pump. I can choose btween that and 98 octane but the E85 makes the car a bit more snappier..
Headstuds have NOTHING TO DO WITH HORSEPOWER. They have to do with cylinder pressure.

Edit: Nevermind.

well considering that the stock tune is rich like crazy and E85 leans out a car (according to TTP) explains why your car feels snappier but i would not trust just running it without a tune. get it tuned to help maximize the power to be had with using e85
We have done some recent datalogging of different E85 setups and have determined the injector duty cycle on various sized injectors on setups using ethanol. With this additional data, have made some adjustments to our estimates based on this additional information.
ohhh, i see.. so basically you just made a mistake when you put your answer?
