Stock Fuel pump

[801NSX]

Question:
How much flow can stock fuel pump can flow? GPM and CC rated...

If anyone knows how much HP level it can support as well that would be helpful.
I understand about 400HP is maxed with a resistor (?) bypass.

I wouldn't even risk it, just replace it with a Walbro, it's cheap insurance. NSX pumps have been known to not be able to keep up on "low boost" supercharger kits for years(*when the pumps/cars have some decent mileage under their belt).

yeah the walbro is cheap, but the labor to install it isn't (relative to the price of the part at least). I'm not even going FI just yet but I recently bought a new pump. My car has 84k miles on it and had a CTSC for some of that time, so I figured it wouldn't hurt to put on a new one just so I know it is ok. SOS says the walbro 255 does 60% more flow than OEM, so do the math. :biggrin:
