Default Fuel pump help

I'm getting the UPP Twin Turbo setup on my car right now and i also installed there fuel system with 80lb injectors. I got the upgraded bosch 044 pump that works with my stock fuel pump untill it reaches 5psi then the bosch kicks in. I'm going to be running 10psi with e85,am i going to run out of fuel or should i upgrade my stock fuel pump too? Thanks

You will probably need more pump(s) on E85.

So if i take out the stock pump and add another bosch 044 you think that would be good?

I'd roll the dice with the stock pump and the external bosch on a hobbs switch.

Im running ID1000's, and at about 10psi im at 65% duty cycle on e85, you will be running close to 90+ because of the smaller injector and you run the same base pressure while i use a RRFPR.

I would go with the c6z pump.. Btw Shoaf had a great idea. Hobbs switch for c16. I would make a peck-**** for your fuel tank (for draining). Run 93 octane and when you wanna race it, drain the fuel, put xx amount of c16, flip the switch for kill mode. Run 10psi on stock b/e and be fine.. My car held 11psi quite well on 93 octane..

I want it to be safe all the time,Im going to be running e85 24/7. If anything i can just drop the tank and put a walbro 416 pump in there.
