I'm putting togethor a standalone set up. Are the Holley black pumps reliable? I know that they are pretty much bottom of the barrel, but it only needs to support about a 200 shot. Just wondering if there was any reliability problems with them.

Andrew,
The Holley Black pumps are fine. I have used them i the past on many systems. Keep in mind they do not come with a regulater. I suggest running a return style regulater..

i was wondering the same thing to day. I am building dedicated fuel system. I wanted to use the holley blue pump. I would like to know if it would be enough to run a 400 shot with this pump. I need a good plate system for my victor jr setup. Could i use the holley blue with a free flow rate of 110gph or is that not enough for a 400 shot

 

Sounds good Dave. I was planning on running the Aeromotive regulator that's made for the A-2000 pump. It seems like a nice peice for the money.

BTW: How much would your 3qt tank that goes by the fuse box be by itself? I'm not sure if I have room anywhere for a standard 6x6x12.

 

I'm running a blue pump and spraying 350 and never had any issues.

 

anyone know if theres a chart for low pressure systems that recommends the gph needed. also how much pressure does a low presure system use. I will be running the gemini twin nx kit. thanks

 

I am surprised that more people don't run a walbro high pressure system. I would think that it would keep more accurate pressure. Low pressure is effected a lot by alltitude if you race at a mid elvation track like I do.

 

I'm still considering a high pressure system. I though it would cost alot more to build but I found a regulator at a half decent price so it may not be so bad.

 

i thought i read some where here that the low preesure system is better and easier to tune on the dyno. nitro dave how about some words of wisdom

 

I run a holley black pump, the benefit of a low pressure system lies in the ability to make small changes to pressure and big changes to richen/lean the AFR. It can also be bad though if you drop a PSI, it could change the AFR a point or two.

If you call NX they have jet sizes for a low pressure system. They run on 9-10psi.

 

I personaly prefer a low pressure directport system. It is easeir to tune and you can get smaller size hp jettings with out making the orfice in the jet so tiny.

Both will work. I just favor the low pressure.

so dave is the holley blue pump enough to support a 400 shot thanks

 

I have been talking with NXricky at length about what pump to use for my Direct port system. I am leaning towards the Holley HP 150 pump, which is a better overall pump than the Holley black or the Holley blue, and it flows more. The HP 150 "supposedly" free flows 150 gph, flows 140 gph at 7 psi, and 136-137 gph at 10 psi. I think that pump will more than support my 300-400 shot.

 

well i just ordered the holley blue as long as it can support a 300 shot i am alright. hell thats why they make fuel pressure safty switches

 

i run a blue pump on my DP system also...

hell im very good friends with the Holley truck driver that takes the truck to all the NHRA events and thats the pump he reccomended...
