PSC N-Style pump any good?

I am wondering if anyone has any experience with this pump?? SP1500AX, I have a P pump now but its going to be a pain to mount to my 6.0L so if this pump is better and it is cake to mount I would like to get it. I searched but didnt come up with much on it, any help?
Thanks
-Chris

The N Pump handled R's way better than a P Pump.

Only had mine in use a handful of times, but so far so good. 2.5 rams, front and rear steer and the steering is fast.

PSC N-Pump is way to go with LS motor and truck accessories. I just got one a while back!

N-Pump wont let you down. We use them 90% of the time at the shop. We actually built our LS bracket kits to use the N-Pump exclusively.

The pump fit right into the factory vette ls1 mount with a little grinding, but bolted right in.

Its a great pump for the money. Its not a Howe Trophy pump, but its a fraction of the cost. WAY more reliable than a TC pump.

What is the shaft size on said n-pump? Does it bolt right in where a TC goes?

Chris have you found the psi and flow at different rpm ranges. So you know it well work for riding or racing rpm's. It would suck to get a crawl pump if your going to go fast.

I would run it with a big cooler.

can an N-Pump be put in the place of a P-Pump on older V-belt drives on a SBC? Any brackets available?

The N pump bolts to 2 holes on the front of the drivers side head. Psc sent me a spacer/ isolator for the f body belt track, I made a 1" spacer to put it on the truck belt track.

Has anyone mounted one on a 4.0L yet? Very happy with my steering in the buggy but the jeep is still sub par.

Awesome! I am going to be running truck accessories also and was wonder what the spacing was going to be like. I love the fact that this pump lines up with the holes in the head. I was trying to come up with a way to easily mount a P pump but then a customer we are doing some work for got this N-pump and I was shocked to see it lined up.

Yeah I don't think the N pump will bolt where a TC goes, the CB pump will though I think. N pump is a great pump for the money

PSC N pumps are the shit, I have a spare on the car that I may have to sell soon just so it doesn't rot away!

But I baby mine.

I've mounted several on 4.0's in Jeep TJ's. PSC makes a relocation bracket that bolts it right up with a longer serpentine. I've done probably 4-5 of them with no issues and lately have been using their CB pump.

Do any of you experience start up whine with the pump?

I installed a high volume (HV) PSC N-pump in November. Whined on start up from the beginning but calmed down and made no noise after 30 seconds or so of run time. The whine progressively got louder/longer after start up but has always been quiet when wheeling. Pulled sepentine and spun pump by hand, noticed some light grinding noises in pump so I pulled it. Metal flake all in fluid from pump requiring a full system flush.

Spare pump is standard volume N from PSC installed last night. Started up to hear the familiar whine and just like before it quits after 10-30 seconds.

Fuild was Valvoline - Switching to Amsoil hydraulic now.
Diagram of pump feed is attached - total length is 6-7"
*All 5/8" diameter fittings
*Hose from PSC

Could be the fluid. My setup looks basically identical to your diagram and I've never had a quiter, smoother pump. It has also been the easiest system to bleed air out of. I know I had a ton of air in it at one point and I was able to bleed the pump and get rid of any whine within minutes. Amsoil is good stuff. I would try that and report back. I run the KSE Elixer. Pricey but badass

What diameter is the pulley on the pump?

Why not switch to GM power steering fluid?

Is your system vented or not, balanced or not?

You and every pump supplier for offroad steering that I've talked to including PSC, Lee, and Howe.
