Switching over to E85 and was wondering if anyone has at suggestions for the best in tank single fuel pump for 500whp+?

 

If you are running ID2000 or FIC 2150cc, you can run punched down walbro 255 hp, and just adjust your BFP down to like 35psi, this will allow you to get into the 600whp range.

If you cannot lower your BFP then an single 255hp will make it to about 450-500whp in that range. Best bet would be to go with the walbro 450 e85 version, forgot the part number. But that might overrun your stock FRP or stock return system.

 

That's what I'm running and no issues at all. HTA Green on 30psi E85 using that pump and FIC 1100s making 500/410 on VirtualDyno.

I was running Aeromotive 340 before and also Walbro 255 both couldn't fuel enough up top. Haven't had any issues with Walbro 450 except it was a pain to install. Had to dent fuel tank a bit to get it to sit flush.

For $134 shipped you really can't beat it...(same seller I bought from BTW)

what did you use to dent? how much of the surface did you dent? And thanks for the link.

 

You don't need to dent the tank.. Just cut the housing properly.. There are instructions in the how to section..
