Iam sure this has been asked a lot, But iam new to site, so need some advice, were thinking of switching over to e85 on my daughters camaro, and would like know what would be a safe limit an with a decent tuning window. big shot plate. 406 sb 11.1 comp brodix -8 heads. Want to run Straight e85 on motor an bottle. Thanx for any help.

 

Anyone?

 

People have used E85 some people like it some don't and want to spend $15+ for some fuel. I have ran it on carb/nos and all I did was raise fuel psi some from gas setting. Do the same for timing 2*per 50 or more until tune is clean then add timing back watching mph.

Anyways I have done 200 worth but people have done lots more just watch your tune and take small steps

 

go 250 shot

 

What are the rings gapped at.

 

e-85 and nitrous work great together, and its cheap and forgiving..for 11-1 CR, you could get away with mixing in more pump premium, and skipping a lot of e-85 carb mods..i have run e-85 thru edelbrock/afb type carbs with only jet changes, but i would advise mods for a holley type..

that being said, i have run lots of compression, with nitrous, and added timing..it didnt die..

its always best to flow your plate, but e-85 is so easy to work with, just go fat, and work backwards.....

 

Depending on setup and tuning job. A 200shot would be a good starting point.

 

We do alot of E85 nitrous set ups. Its doable. The main issues are..

1. Specific gravity at the pump is all over the place. So you need to stay on top of the tune up.

2. Reading spark plugs on E85 is completely different than reading plugs on race gas.

3. You need to make sure the fuel system is up to par for the extra demand.
