Well i want to try ethanol e85/e70

i have one walbro 255, 1050cc injectors, fp3065 turbo

do i need bigger injectors or double pumper ?

 

I def suggest a double pumper, the last thing you want is to run out of fuel. Check your idc's after that, if needed upgrade to some 1250's or something.

 

Most likely you will need both to get the most out of that turbo.

 

^ He would know.

 

You will need both. I maxing 1200's out oin a Walbro. When I black I'll need a double pumper and at least 1650's

 

im not aiming to max that turbo.. i know i wont be able to do that with one walbro and 1050cc if i remember right my IDC is at 65% on 21 psi on pump gas.

 

A single Walbro pump cannot max 1250s with gasoline, much less E85.

1250s with an adequate fuel supply is good for 600+whp with E85.


FYI

 

1450's should be enough for your setup on a double pumper, I'm seeing 94% IDC on 1450's and double pumper. However, I did up my base fuel pressure from 43 to 48psi for a little headroom.

 

Sorry to steal the thread for a min, do you guy think I'll be fine w my set up for e85 and not max anything. Single walbro, old school fp green,and I'm looking for around 1200 injectors, @ 28psi.

 

with an old school green you should be fine with 1 modded walbro at 28-30psi.

 

Well, of course you can drive on ethanol with 1050cc injectors and one walbro. You won't be able to maximize your turbo, but you can certainly still make good power.

I have a Non-HTA green, 255 walbro, E85, and 1200s and can run 35psi without maxing out. You should be good at 28psi.

 

Thanks for the I may go for 30psi, ... What does a moddEd pump do,?

 

Flow more.

 

Abuddy of mine made 500+awhp on e-85 on a single modded wally.

Here's a little cheat sheet for E-85 injector sizing. This is assumed you have 43.5 base fuel pressure too:
