So after doing some research, talking to @71chevytruckguy and looking the build @BigSouth has going on by @mcutler i want to run Scott’s Custom Offroad pump.

couple questions… I have a goat built bracket for my 6.0. Would his pump fit my bracket with his “standard” bracket?

do I need to ditch my bracket and go with Scott’s high location bracket? Then relocate my alternator to the passenger side?

this is what I have.

Also, do I need to run a bigger reservoir for this pump?

Probably not without modifications. I had to ditch my GoatBuilt brackets. They too are specific to a style of pump. I had a P-pump and it’s different than the gear driven one from SCOR.

SCOR also recommends a larger size reservoir. Especially if you’re doing anything with rear steer. He told me that my PSC reservoir should be “fine”, which has Matt contemplating ditching it for something home made instead. Matt can probably give you a better answer on the feed line size, but I do remember him saying it needs to be bigger than usual.

I was hopeful because the bracket I got was for the stock pump to be used and moved higher. This pic shows how Scott had it mounted on a stock bracket.
Not sure if the pump being deeper would interfere with something. Kinda like how it got into your coil pack. But mine would definitely be lower and I feel like it’s going to be too deep.

That picture looks like the pump and your upper link would want to occupy the same space.
 
Depends on your chassis and link layout. If your links are placed outside your main rails, then the low mount will work; but if they're inside, you'll need to ditch the stock acc bracket AND the GB unit. I assume you are on truck spacing, and assuming you cannot use the low mounting on stock acc bracket, I would relocate Alt. to passenger head, and use Scott's bracket on driver's head with coil relocation. The Scott's pump has suction...therefore it can withstand being equal height to the resi, or even a tad higher. You can use the PSC resi on a single steer application, but you want as big a feed line as possible- likely -12 from resi to pump. For instance on the shop buggy with dual steer, it was recommended that I use -16 suction, -8 feeds to valves, -10 returns from valves to filter housing, and -12 from filter to resi- but I'm dual steer with 3x9 rams- Scott recommended 1 gallon resi on mine...


I will likely cut up Brian's PSC resi, reuse the base and filter, and create a larger canister on top of it.

The great thing about Scott's pump, -$20 for rebuild kit, or $130 for a new pump. But he has never replaced or rebuilt his own personal pump in years of competition on a dual steer rig.

That’s what I was wanting to know. Thanks a bunch. I’ve got a Howe reservoir with filter I could do the same with.
Im running a goat built 4 link subframe. Looks like I’ll get the high bracket and do what you said.
I punched the numbers and depending on how much steering I can get out of my 05 60 I was going to run a 2.5x10 limited to what I need or 8.75in ram.
 
As said before, you can't re-use your brackets.
As far as hose sizing, doesn't matter if you have rear steer or not. @mcutler sizing is what you want with such a big pump.

Anyone know how these pumps do at higher RPMs? Was talking to @tw89yj this morning about these and he asked me. I didn’t know for sure.

they're rated to 6000 intermittantly and check valve pressure set to 2000 psi, per Scott. That said, he has numerous bouncers who compete and have been succesful at higher RPM's

Seen that many times. I wouldn't hesitate run these pumps at all.

PS : On a standard LS, your rev limiter will be around 6/6500. No need to overthink this.

Yep, I noticed that Scott had a stock sized pulley on the pump. Just wanted to be sure I was assuming correctly.
