[USMC_Turbo6]

What should the fuel pressure be set a for E85 and 120lb injectors?

What fuel pump what engine management system?

Red Armstrong double pumps and sd2

 

[Boost231]

Why not just set it at 42 line off? I haven't run Erics chip in a long time but I do belive that to be the pressure he likes it set at for his chips.

Eric recommends 38 psi line off to start with for injectors 120lb and larger . That's the info that came with my 6.1 E85 chip & 120lb injector combo .

E85, 120 lb injectors, versafueler,6.1 chip, single 430 pump, I run 50 lb base line off. 21 psi boost.
Last time at the 1/8 mile track ,idles great, 70% duty cycle, ran 6.88 at 100 mph. Lifted a wheel for the first time too. Couldn't be happier.

Thanks Regal. Do you have a volt booster for the pump? Also what size lines are you running? Our combos are very similar. Wonder if this pump could support a 10.50 car on E85.

Thanks

Dash 8 to a large filter then a Y to dual feed the rear of the rails. Dual Dash 8 return into Magnafuel regulator, then I used the stock feed line with reversed filter as the return to the tank!
I am going to add a small surge tank with the new Deatchwerks 350 E85 pump, the surge tank will be filled from the return line with an overflow Dash 8 from the top of the surge back to the existing return to the tank. I will put a Y in the feed line just before the large filter, it will have a check valve in it. I will hook up a Hobbs switch to fire the pump under boost.
The tank holds 2 liters which will be more than enough for a Drag run. It will be topped off constantly from the return.
It means I won't have mess with the current pump. It will be enough fuel for way over a 1000 hp.
