Can the stock pump maintain 30% nozzles?

Well not the results we were hoping for. On the xrace tune I could only maintain 23,400psi rail pressure. That's with 60's, stock hpfp, Elite stage 2 low pressure system, ported rails. I was able to maintain rail pressure while cruising but once I layer into it it would drop to 22,600psi then climb to 23,400psi. Rail pressure would drop off and then pick up again so it was trying but there's just not enough volume output in that pump to keep up. That being said I would say xstreet is bordering on the limit of the stock pump. So theres the info you guys were looking for, sorry I didn't log the runs as I was busy keeping it on the road since it was a little slick were I was driving.

My pump has 60,000miles on it so it could be getting tired but who knows.

Thanks for the results. I guess that answers my question good enough.

Yup, different tunes may act different thou but it looks like the stock pump can only hold 60's on the xstreet and who knows how long it can last at the duty cycle.

Thanks Shane, I needed this info so I can decide on HFPF fuel upgrades especially if I go larger than my tow powers.
That's not terrible tho.
I bet that is still making more power than xstreet
I.think that's good news...
The reason it drops like that is because the volume valve goes 96% fast and the pressure valve slowely compensates to reach full rail.
Honestly 23400 is great for a stock pump and nozzles
Mine would only do 18k with 110s and an air dog
Some days it would do 20k but that's the Best it would do.
The best way would be to.get a tune that's like 2.15 or so to maintain full pressure and Max ow for the nozzle

That's Erics tune from march 2011. It's not horrible but it's not perfect. Glad I could help out.

What do you guys think about the old elite modded hpfp and 85s? Id like to a bigger pump but id rather do 85s with this pump and get a ported intake manifold if I can

the original Elite hpfp was only designed for 60s if I remember correctly.

Ya that's what I thought to but back then they also said the stock pump couldn't fuel 60s. Mayne ill wait for the mew elite DIY kit. Dual fuelers is overkill for a daily driver and I don't trust the industrial pump

I am thinking about the same thing, if I dont go to dual fuelers.

It held more rail pressure than I thought it would. pretty impressive for a stock setup.

Good info Shane. Like Dustin said, that isn't that bad.

It's not bad but not desirable either.
