Timucin,

all depends on how much fuel your engine will require at WOT, peak rpm and "off nitrous", and how much nitrous you're gonna spray and where in the rpm range.

If your fuel pump is rated for a fuel flow good for lets say up to 550 hp, and you're running 500 hp out of your engine in "off nitrous" condition, then, if you're not using nitrous just for a "turbo spooling up" device in low rpm, I guess you better use another fuel pump with a dedicated fuel filter and fuel line.
I would always stay 10-15 % away from top flowing rate of either fuel pump and fuel line (don't know how much flow OEM fuel line can allow....).


How much extra hp are you willing to add with the N2O shot?

I'd suggest running separate pump for the system, be interested to see how that works, cos it would only need to pump when you use the system, but you would need a delay on the NO2 injections otherwise it would arrive before the fuel and run very lean.

What controller are you going to use with your NO2 kit? (Call it NO2 and not NOS, cos thats some nasty American brand and from what i've seen / heard, poor quality too)

Sounds like your car is going to be an absolute beast when its running!!
