Running 80lb injectors on single pump

[psycho6cyl]

Can I run 80lb injectors on.a single.pump. thought I read some where you need a dbl.pumper. Looking for 10s. Planning on.upping whole whole fuel system next year. Pump is new and hotwired. Any real downside running 80s on the street? I have fast xfi also

The single pump is?

It isn't a problem. The injectors will support more power than a single pump, but if you are within the limits of the single pump, then you are fine.

I run the same thing on my car with racetronic single pump.

I have a replacement pump from full throttle. Possibly a 255? Boosted have you ran yours at the track w single.pump?

I run a single DW pump with 80's. Without a volt boost it can support the injectors up to about 70-75% duty.

With a volt booster it can get close to 100%.

Ofcourse wiring has to be 100% all the way to the pump, including top notch stuff inside the tank.

This should max out a set of 80's on a single pump. Your DW pump was a 340 pump right?

DW300 was commonly advertised as 320lph. But they've made some recent changes to bump it up a bit more....

No Jeff. I only run on the street but I can't keep my 19 inch wheels planted. It spin every time I hit the gas

Sure. You'll probably need new fuel lines to control the pressure on that 430 pump, but it's a single that will supply 80's. As far as stock lines, then a double pumper works better as it's easier to set the fuel pressure for driving around. That's one extra pump to fail though too.

Jeff i also have AN8 feed and AN6 return

When I wrote that, I was referring to 255lph style pumps. I'll change that to clarify. The main point is, you will only get as much flow as the fuel pump can supply, as already mentioned.

Ok thx Eric. I just didnt want to do future upgrade and hurt myself at the same time.
