Building a 12.25 to 1 454 plan on running e85,the old buck building my motor likes cast rings,would that be ok? i read alky motors need moly rings?

Mark Riles

If he's building the engine then he should use whatever you ask him to use. Moly rings are wonderful and if that's what you want then you tell him that's what you expect.

You're going to run fuel that's 85% ethanol? May I ask why- most of the guys here get their shorts in a twist with 10%.

Greatsteaks

Off topic but does Everybody know why it's only 85%???

Because if it were 100% people would drink it!!

Cheap fuel for high compression or big boost.

It's only 85% ethanol, because engines cold start much easier with some gasoline mixed in. Actually all ethanol fuel is denatured(poisoned) with 5% gasoline, before is allowed to be transported from the distillery. Not sure if the original 5% poisoning is factored into to the final 85% ratio though.
