H/C Dry 200 shot on e85? I'm trying to figure out what route I want to go with my project over the winter. Right now I have a set of ported heads and a cam for my motor. Forged internals and 11:1 CR. I planned on running a hidden dry 200 shot.
Just bs'ing around my buddy asked why not go e85 and not have to worry about running race fuel whenever I beat on the car. e85 is readily available right down my street.
My questions are
1) is e85 and a dry shot going to work well?
2) how crazy of a fuel system would I need if I did so?
The car should make upper 400's on motor plus a 200 shot.
Fuel system right now is racetronix pump with hotwire kit. 60lb injectors and Speed inc high flow fuel rails.

E85 requires up to 50% more fuel than gasoline at WOT, so the engine will be very thirsty.
But if I had to guess, I would say that your 60lb injectors and the fuel rails should be fine. However, I think your pump will be severely taxed when you hit the engine with spray.

that fuel pump is only good to about 500-525 on regular gas...and that is pushing it
you will be out of it on motor only with E85
60lb injectors are big enough to do a 200 dry shot on regular gas...but no where near big enough to do it on e85
you are going to need something more in the range of 75-80lb injectors to do a 200 dry shot on e85
you will also need to replace stock fuel lines with -8an feed, and a -6an return with a Fuel pressure regulator as well..
you are going to need(not optional) a dual fuel pump setup to do a 200 dry shot anyways, and especially need a good one to do it with e85
(I highly suggest a Nasty Performance stage 3 street kit)
quick math in my head, says you need to have a fuel system that can flow 400 lbs/hr+
and on e85, its going to need to flow 500-550+ lbs/hr or more
(not talking injector lb/hr.. talking about fuel pumps)
the stage 3 street kit has a Dual pump setup that will do that with no problems
as a reference... a walboro 255 flows about 400 lbs/hr
an areomotive a1000 flows roughly 500 lbs/hr
