Fuel Pump questions...

What kind of fun can you have with a high flow 255lb fuel pump?

Noticable difference?

Same crap?

It won't gain you any horse power, but they say that they are good for up to 800 HP.

Re: Fuel Pump questions...

I'm currently having Fuel problems... In reference to getting the fuel where it needs to be more efficiently.... is the 255lb good?

Planning on:

Z06 MAF (got the old MAF wet)
255lb Walbro
Hyperjunk Fuel Pressure Regulator (screw the PCM I'll try it anyway)
36lb Injectors (I think mine have had it)

Should that be some good performance gains fuel wise?

Re: Fuel Pump questions...

Yeah, that's what I got. It would take alot to use it to the max. So that means that it's duty cycle will be very low, which is good. Maybe as low as 5-10% during normal driving.

Re: Fuel Pump questions...

I plan to put the N20 setup back on the car (regret taking it off ) and get the LT-4 stage 2 heads on there. That's the short term goal... the long term goal is a Turbo charger.

I just want to get everything right the first time while I'm toggling with the fuel now.
