Well my engine builder and I have been having some very interesting conversations on this build. He is an old school pulling truck guy. We agree, detonation on pump gas is what will know will knock the bottom end out of this build......So in the interest of allowing a bigger tuning window, we are considering dropping to 8.5:1........
As far as E85 goes, I could go that route as it is available near me.....My issue, my carb guy doesn't do E85, or blow thru.....So that leaves me with a big problem and I will need to find a carb shop I can work with. EFI is not an option due to rules. These things don't tune themselves. Thumper has been great at helping me dial in my junk over the years. I will get back to you all on that one.....I need to research more, because I think your right as far as tuning goes, the E85 has a bigger window and I don't need an intercooler, but also because I do not have the room for a bigger radiator and making this kind of hp on my tiny bracket setup may not be all that cool in +90 heat....My fuel pump is good to go already upgraded that this past summer....
