Question Switching to E85 on NNBS

Fuel system question. Running a ZL1 blower with heads and cam. Running 10 psi now making 530 on pump gas will be on 15PSI soon. I have 90 pound DW injectors at the moment and wanting to switch to e85. With 90s be enough injector and what intank pump do you guys suggest on running? Single 450 or dual? The truck is already a flex fuel truck. Just need help deciding where to go with the fueling I would rather over kill it because it will be making more power down the road.

run dual 450’s. It’s gonna be a little overkill, but I don’t think one 450 will cut it at 15psi range on e85.

That is what I was thinking. I don’t think the 90s DW Injectors will cut it either. What are you guys running for Injectors. Shooting for around 600-650 on boost and 700+ with nitrous.

When the motor lets let’s go I’ll be putting a 383 stocker in it.

Go 1000cc (110lb/hr) injectors. They can do over 800whp if you are running 58psi of fuel pressure on E85.

Single 4303 and some 127lb injectors will be enough for your power level and be good to about 1000 on e85.

magnafuel just released the 4303 in-tank fuel pump setup!! That would be all the fuel pump you would need for sure!

got anymore pictures of how you set it up.

What do do you guys think of running bosche 210s? Or what Injectors would you recommend that won’t brake the bank.

oh yeah, using the 4303 in tank isn’t anything new..... But magnafuel did just release a New 4303, designed specifically for in-tank use and it’s universal ( but it’s a different part #)

I would just use the injectors you have and see where they getcha. Surely you can be in the 650hp to the tire range with the ones you’ve got now.
