I'm changing over to E85 thinking that it will be cheaper, cleaner and more readily available than race gas. (3 stations in our area have it)
The setup is an H22 hatch, GT30, 700cc injectors, 10:1 Arias, sleeves,Crower rods, Hondata S300 etc. It makes 468 whp @ 16 psi.
I have a set of 950cc injectors but need information on what size fuel pump will work. Would a single Walbro 255 be adequate for this setup & around 450 whp?
A shop I use says a Supra Walbro pump will run around $300. I see ads for Walbro 255 pumps for around $98 - $150. Are these the same pumps?

 

Anyone with experience on a 600 whp honda using a 255 walbro 255 with race gas? I also have an additional inline pump in place.

A regular walbro 255hp intank pump and 1000cc injectors is good for 450-480whp.

 

Thanks for sharing your experience and knowledge. E85 info can be harder to find.

an E85 fuel pump would basically be an external pump. ive never found a pump specifically for E85, just alcohol.
