I dont want to get into a debate here, but will say this, I dont like how the yanks make e85 with corn crops, thats just wrong, I do like how csr use a by product.
I cant argue about the soot as I havnt researched that, I would be suprised if there were any elements worse that unleaded, Unleaded is a disgusting fuel! one bonus about running E85 is it burns cleaner and doesnt leave the rear of my car dirty, unlike 90% skylines around. Check out Guiltoys e85 thread, he took his car in for emision tests in NSW and passed easily, running 330+ Rwkw from memory.
As for a injector duty, pound for pound 30% duty on a power fc sounds about right. But who wants to run same boost!
