....premiums are out of my budjet though...maybe I need to just leave it alone until I can do premiums.

I just got my April issue of Diesel Power the other day, and there is an article in it on the HUEI system. It says the difference between the 15 and 17 degree pumps is the angle of the swashplate, which can vary a good bit from pump to pump, so niether are a true 15 or 17 degree pumps. That was just a term that stuck to help identify the earlier and later model pumps. I'm just quoting what the article says, but if that is true, then maybe an upgraded T500 from Joey is a true 17 degree pump and could be better than a stock '99.5 to '03 "17 degree" pump.

I'll gladly scan the article in the magazine if you wish.
They are morons when it comes to powerstrokes.
Well, the guys who usually write the articles are.
This one I'm speaking of is really funny.
They talk about the different injection systems in the trucks and completely screw up the powerstroke info.
So the next issue they correct it only to screw it up yet again.
Really shows you how much they think of fords.
Specially since a majority of the magazines are dodge this chevy that.
I just stopped bothering to buy them.
Their performance upgrade suggestions on powerstrokes were crap and un-educated.
They just spend to much time trying to make our trucks look like crap and that you cannot have a nice performing truck unless you replace everything but the block.
Now moving on to what your saying about swash plates.
To MFG pumps that far out of tolerance and spec would mean that half of our trucks would just be absolute piles of crap.
You mean to tell me that with the MFG processes in the last 20 *explicit deleted* years that we cannot manufacture within close tolerances of 15°??? or 17°??????
GTFO
The pumps were changed to ramp up oil pressure and flow for the larger injectors of the super duty trucks.
It wasn't a "manufacturing mistake in tolerances."
Yeah, let's just make **** up!
Lets think about this really simple, cause this **** is really really just rocket science.
It's a round piece of metal with an ANGLE cut on it.
....
That's it.
a round piece of metal with an angle cut on it.
That's it, nothing more.
You cannot have that much of a variance in a machining process to just claim they were "way out of tolerance."
Even if you cut the efffing things with a band saw you would not be that far out of spec!

Well, they really aren't in my budget either LOL!, but by the time you replace what parts need replaced doing the budget builds, you'll be so close to premium build price, you may as well do premiums. I may be wrong on that though. Your best bet would be to call Jim and talk to him about it, I may be telling you wrong LOL!

Yes, the T500 is a 17* pump that has been gone over and is suppose to be a little better then a 17*. How much, I don't know, Talyn probably knows because he visited Joey and got a 'tour'.

Diesel power also says that you dont need an HPOP for a HEUI motor to run.

Speaking purely based on what I do for a living, it isn't going to create that much more flow in the "2 degree " variation between the 15 and 17 pumps. If the pump was designed to be serviceable, then u can modify your pump to create more flow with adjustments to your flow control and relief settings. U can also add shims to increase your swashplate ramp degree to get more out of it as well. I design, build & repair hydraulic pumps, motors & valves for a living. The factory always sets things way low on stuff so as to get maximum life from it. By the looks of the pictures of the T500 hpop, its probably manufactured by Bosch or Cessna. I will look at my brothers pump and see if I'm right.

It's just a rotary style pump.
Your stroking the cylinders more with the 17, and there are gains.
Volume is king. Not PSI.

You are correct. People are ate up about the psi. If the volume isn't there, then cavitation is eminent. It will end up destroying a lot of stuff. I still saw a few external adjustments on it that I am going to look into the factory info at work to see what Max parameters we can mess with. Just trying to save my bro some cash if I can!!

The 15 to 17 change though will net you more oil per stroke, which is more volume, thus letting the pump work less hard creating more PSI when demand is higher due to more volume.
Joey's pump is going to modify the journal bearing pumps into a ball bearing pump as well.
Which is well worth the upgrade alone.
