Dynosty presents Walbro 485, E85 fuel pump
you have more than enough injector. you need more fuel pump
I'm trying switch to E85...my current setup uses 1000cc/Walbro 400 for 91 Octane w/ meth...I will also be running with an ATI crank instead of my fludampr, so my boost will probably increase as well...
So just to make sure I have some margin, how big should I go with the injectors to run E85? Or shoudl I just focus on upgrading my fuel pump to the 485 or a twin pump?

Any Info?
I just finished building a custom twin pump assembly with one walbro 255 and one walbro 485. Its headed out to someone who is going to be testing it in a high power car that is converting to E85 i believe.
Should be interesting to see how all this pans out. It was a nightmare for me to assemble (will get better with practice im sure).

he swapped a 255 for 485 and then had to align the inlet with the hole in the canister.
I replaced one of my 255s with a denso hi flow. it doesnt align with the hole in the canister, but works fine. But for a production part, i'm sure Phunk wanted it all lined up.

Max HP will depend on a few factors, such as boost which directly relates to fuel pressure which directly relates to pump flow. Assuming a great flowing system with minimal restriction, the 485 should support around 900WHP - while the injectors would support slightly less, around 850WHP. These numbers are estimates only, and based on WHP using gas as the fuel on our Dyno Dynamics. In your case, using the stock fuel pump hanger, there will be some restriction there thus lowering flow slightly.
They are in stock and we can ship out today.
