PWM fuel pump control.
Re: PWM fuel pump control.
Oh yeah, forgot to say that all 10 injectors are fitted to the car, so when the nitrous is turned on nearly all the extra fuel comes from the 5 x 630cc injectors.

thats a lot of fuel! what is it? probably need to look at American drag stuff, or bugatti pumps and the like

Re: PWM fuel pump control.
You wouldnt need another 450 to fill. Dont forget that pump is running no pressure so will flow a lot more.
Plus as you're returning fuel back into the swirl tank, the lift pump only need to flow enough fuel for the power the engine is making at the time.
Only when you exceed that will the swirl tank start to empty...but with enough capacity unless it sees extended periods at high power/WOT, then chances of it ever being a problem is very slim unless lots of standing miles or similar.
So most of the time there will always be excess flow into the swirl tank.
But yea the pair of 340's etc looks all good and neat you could fit it all in tank like that.
