How to run your LS1 on E85

It should also be noted that the ethanol will do a super cleansing job on your fuel tank and fuel lines and you should change your fuel filter probably within a week of using this fuel to avoid clogging other parts. Your lines and tank will have a lot of varnish on them from years of using regular gasoline, the ethanol removes all that varnish.

You definately dont want to go over 85 0r 90% DC.

I did test run my car on 100% E85 with stock injectors and had DC well over 100%

Just look at the Saab 9-5 Turbo with Biopower engine (big seller here in Sweden) that when it is fueled with E85 gives 20% more hp and 16% more torque compared with regular gas.

Hey Runn, yours will be a unique turbo build, your going to get more than normal power that pump gas will give you running the E85 as of course it is a higher octane rating. Ive been thinking, and I bet you could get away with 9.5.1 even maybe up to 10.1 CR with the Twin 37's. The reason you wont run that CR with pump gas (93) with say 15 psi of boost is because you will get knock the more boost you run which is bad of course, but since your running around 105 octane, you wont get that knock and can safely run that CR with say 15 to 20 psi of boost. Definitely keep us posted on your build I am very interested in this as hopefully by the time I finally get out of this country and go back home, they will have E85 readily available. You will at least want to change the springs in your Heads as the complete stockers are not good for boost. You will also want to get some type of boost pistons, im going with Mahle pistons. Especially running high octane fuel, your stock pistons could be bad news for your stock bottom end. Of course since you were already pushing your fuel injectors going NA, you will definitely need to up those as well along with a good fuel pump. Let me know how it goes.

Yes E85 is perfect for boost

Excellent info.
I have been doing alot of research on E-85 also. It is readily available here in Columbia, MO running around 1.50 +/- per gallon.
I have also done some forced induction testing with excellent results!
I will have LS1 Turbo results soon!
