Im doing a mild stock frame build over the winter and im going to have a dual map tune for pump gas and e85. Im going for 500-550 I was looking into the wally 255 but from what I seen that either that pump is to small for thems numbers or that pump isn't that e85 friendly, so I looked into the wally 450 that is rated for e85. But then I seen some fuel regulator concerns? any help on any of this?

 

walbro 450 with fpr setup or double pumper(dual 255hp) with hobbs switch....those are your best options, you could also go 255 with 255 inline..

 

I was thinking about going with the 450 and a fuel regulator, but im not sure which regulator to go with? just trying to get options

 

Yeah get the FPR, Walbro 400 and large injectors and be set.

I'm currently running the Fuel Lab FPR, Walbro 400, and FIC 2150's. MAP has a sweet package deal too...

Im currently making 500hp at 25psi. I have yet to have a fueling issue and have enough fuel for days

 

1200-1450 injectors, double pumper and STOCK regulator.

 

Fast stuff

 

Whtss e85?

 

Why does it give of so much power
