Couple things to consider 1. oil changes need to be more frequent or you need to step up brad penn oil or joe gibbs hot rod oil 2. its in the 23-25 percent range for more fuel. I am personally running 165lbs injectors, a weldon pump, 60 psi fuel pressure and was making 1004 sae whp. no knock, on 10 -1 compression albeit at high elevation. 3. I would still run an intercooler for consistency and safety, but with e 85 you dont have to run some huge or expensive intercooler. 4. I would use the highest volume gas station so you can to insure fresh clean fuel. 5. it will start in the cold(done it under 20 degrees out) but it can be a little rough. On the flip side it cranks long enough to build up oil pressure before fireing which is a positive to me when its cold out.6. Gas mileage does suck lol but spool is better.

The pumps at frankford/midway were E80 as of yesterday, FYI

You can also cut pump gas with E85 too, just remember to change the cal for it, as itll lean out!

Looks like this. It looks like this one.


I think it was cheap. Like under $50 bucks.
