Fueling & Injection - E85 + 150 shot + Stock Internal motor = what fuel setup?

I am building a stock internal LS1 with a 150 shot of N2O on E85. Full Boltons, Vic Junior, FAST 4150.

I have a racetronix 255 with a hotwire kit. My questions are.

Will this pump supply enough fuel for the motor N/A?

What about with the 150 shot pulling off of the rail?

If I need another pump then can I take a standard walboro 255 and put it in the tank next to the race tronix kit and just buy another hotwire kit or is the race tronix pump better than a regular walboro?

Sorry for sounding like a newb. I dont want to not ask the dumb questions now and wish I did later.

im gonna say you will be fine with one... i usually figure one 255 good for like 500hp

Depends what your motor makes NA but as said you can usually do about 550rwhp on the single Walbro and stock lines.

The 550rwhp is on gasoline not E85. You need about 30% more fuel with E85.

I recommend one of my dual pump setups for a nitrous E85 application.
Depending on your total power you may need line upgrades as well.

Let me know if you need more info.... I'm only a phone call away.

You are correct didn't catch the E85 part sorry.

I'd say definitely run two 255 pumps, don't try it on one pump, not worth the chance. The stock lines will be plenty fine though to way more power than you plan on making.

i agree with these guys on running 2. better to be safe than sorry. Nitrous is not forgiving if you go lean

What are you doing for injectors?

I am running 60lb injectors

Cool. Should be good on that front, then.
