i understand you can bump your timing up. but what if you already have a cam inside? how much more can you advance? what ratio would you need in the tank?

i havent heard of mxing e85. I ran it on a car before and ran just e85. my truck runs on e85 as well.

It's basically used as a cheaper alternative to race gas by some people, it runs like 105.

But there's drawbacks, it returns at best 30% worse gas mileage than normal gas, and it will destroy any non-compatible rubber in your fuel system.

Basically you need to upgrade the fuel pump and injectors to something that flows at least 30% more than what you need with normal gas.

you also should have a dyno tune done to get the most power out of it, safely. Because it does require 30% more fuel delivered, but you can run a lot more timing.

E85 burns slower than gasoline so you need to dial in more timing.

The eating away at the rubber hoses is partly true. E85 is slightly corrosive but really any car built after 85 can handle it. The bigger more common problem is it works like a super fuel system cleaner and can knock deposits loose in turn clogging stuff up.

That said I have been running 255 pump and 30# injectors with no other mods to the fuel system on mine for a bit over a year with no issues at all.

My other advise would be to get a tweecer or quarterhorse with the rotary switch to go between tunes just in case you can't find the E85 or want better gas mileage for longer trips.

Pure ethanol? There is no pure E85. It is 85% ethanol and 15% regular gas. Hence the name. That also depends on time of year as when its colder out its harder to start an ethanol powered vehicle so more gas is added. It never goes below 70% though. Seen as high as 90% in summer.

I think he means e100 isn't sold at the pump.

Bingo^^^

Plus if he ran E100 it would be a major pain in the 4th point of contact to start and damn near impossible if it were cold out.

if you really want to do e85 safely you'll need a fuel pump, injectors, and a wideband. E85 is great in my turbo car... i've been thinking about putting it in my 5.0 too, but i'd probably get like 5mpg
