Default Fuel for nitrous track only car

I have a stock pump, with a hypertech helper pump. If I take the fuel for nitrous wet kit from the schrader valve how much HP will it support? I want to around 550-600HP at the wheels.

And, if my stock pump with hypertech helper pump won't support it, do I get a 255 in tank with stock fuel lines, will it support it?

Or is it just cheaper and easier to run a dedicated fuel system from nitrous outlet in my battery tray? Could the dedicated system replace my stock fuel tank too and proivde all fuel, nitrous and N/A?

Track only 1/4 mile car

Thank you!

IDK if you got enough pump to do that....whats the hyper helper flow? the stock line is rightttttt around that hp level really depends on the bsfc at that point.....the rails will handle a metric ton i think the pumps will be ur issue if u have one

Id run a dedicated fuel system. It be alot safer and easier. Be bad to chance it and blow a motor.

Thanks guys

I emailed nitrous outlet support back and forth today and they basically said the same thing.

1) their standalone kit includes a 255 pump, and if I used it to supply engine and nitrous fuel (get rid of stock tank) it would max out at 600HP total

2) stock fuel lines max out around 600HP, so if I put a 255L pump in the stock tank I'd be close to good with a lot of work.

3) if I ever need more then 600HP I would need to use either bigger lines and bigger then 255 pump in the stock tank,
or,
use 2 pumps in their standalone kit to fuel both motor and nitrous,
or,
use the stock lines and what I have now in combination to their standalone kit.

My hypertech 4018 inline pump only supplies 162 lph so I will have to either replace my in tank pump and ditch the hypertech inline pump, or, add the standalone system.

Not sure yet what I'm going to do... Getting rid of the stock tank and fuel system will save weight... but maybe I'm going off the deep end LOL and should just ditch the hypertech pump and put a 255 in the stock tanks.

Really I just need a 255 in the stock tank I guess... or, just add their standalone battery tray kit. Decisions decisions.

Thanks again at least now I know my options

Get rid of the inline pump. Get a 255 and hot wire kit. And run a standalone.

I got a line on a 255 with hotwire kit for the tank
when I spray I'll just add the battery area dedicated.

Thank you everyone
