I currently have full bolt ons, blower cam, 6.0L heads, and a procharger running 6 pounds of boost. I am using a racetronix pump with their wiring kit along with 60 pound injectors. I do have a boost regulated fuel pressure regulator but I don't have that installed, which I am not sure if it will help. I would like to raise the boost to 8 pounds. Can this pump keep up?

that 255 pump will only really supply enough uumph for 51.3# injectors (see fuel & injector sticky here: https://ls1tech.com/forums/2638447-post1.html)

Could he use a boost-a-pump the racetronix harness should have a provision for it.

Injectors and boost are irrelevant.

The power you are making is very relevant. in the UK a single Walbro would be at it's limit at around 500 flywheel HP.

It seems to go further for American rwhp though.

this pump is usually paired with 42's

Typically I recommend them for up to 550rwhp.

bull. injectors and boost are relevant, especially if you are NOT running a FPR.
Are you speaking N/A HP? or Boosted HP?


He could but wouldn't gain much flow

a second pump would have cost you less than the regulator you just bought but would have actually helped.

On a built 6.2 w/ cam and KYTP turbo kit..9psi and made just under 600RWHP and tq on a single 255. Fuel pressure is still staying up in the higher RPM range. But I would add another pump.

Well if you think a 500hp capable pump can magically provide 1000bhp of fuel simply by fitting large enough injectors...work away.

This pump setup is what I am going with for my P1SC build

did you even read what I said? without a FPR boost is relevant.

each and every pump has a flow curve, i know this.

To answer the questions in the first post,

That pump with the FPR will likely hold you, but it will be close.

Going with two pumps (255 s) would greatly benefit you and increase your maximum injector capacity.
