Is there any benefit to be had switching over to e85? I know its better for boosted applications, and I know the car will require a bigger fueling system, but from a power standpoint is there any benefit? Keep in mind I don't have stock displacement.

Thoughts?

 

a lot of boosted applications run it for it's alcohol like properties, often times it allows more boost to be run safely or if you had a high compression application it'll act in comparison

Hey mjr... This post got me wondering about timing... Do you think it would be safe to bump the timing beyond recommended 93 octane limits on E85?

 

^^ that was my next question. Im only at 10.5 compression

 

you can, but with e85 you need 30% more delivery rate of e85 vs gasoline so you better have an adequate fuel system as well as the proper size inj's

 

So it cost less, yet requires more fuel to burn. Always a trade off.

My buddy just switched his STI over to e85. I was looking at it and liked the idea of being somewhat "green", especially in racing. Plus it has the cooling properties. Big *** stroker sitting in traffic on a hot summer day, I would assume the motor could get quite hot even with an adequate cooling system (it's got a ford racing water pump, fwiw).

So would you need to increase fuel pressure by 30%? I calculated my injectors and bought 42lb's, so I wonder if this is enough to run e85

 

not sure if 42's would be enough on a 351 stroker on e85, really only need to do such if you were at the limits of pump gas

 

So I shouldn't switch? That link you posted had a ton of info. Also looked at e85mustang or something like that. I've read it doesn't build carbon like gasoline does. If I were to switch, is it a matter of just upping the fuel pressure and retuning the fuel curve?

 

I would think 42s would be too small. I don't know but, I would think so.

If it was close, I guess you could try raising the fuel pressure to get more volume. The pump will have to support it though, they do bypass at a certain psi.

 

it only costs less because its subsidized by the taxpayers...
