let's talk HPOPs
I'm thinking of swapping to a new upgraded HPOP. Was going to do the 17 degree Bosch one. Only because u don't have to send in a core before u get it. Also I'm building my truck for longevity at this point, and want the engine to run as unrestricted as possible while still using stock injectors.
Couple of questions.
Can u use an upgraded HPOP without a chip to compensate for timing?
What are the benefits of getting a 17 degree HPOP over stock?
What degree are the Adrenaline, and Terminator HPOPs and are they the same as the Bosch 17degree?
What does the degree mean for the HPOP?
Also how hard is the R&R on the HPOP?
Do I have to remove the fan and water pump to get the front plate off?
Thank you guys for the info in advance.

The 17 degree refers to the angle of the swash plate inside the pump. Higher angle pumps more oil.
If you staying with stock sticks, there is no reason to upgrade HPOP. Bigger sticks use more oil, thus the upgrade.
Unless yours is giving you trouble, I wouldnt waste my time changing.

HPOP front plate is only two bolts, can turn the fan to access them. I have to reseal mine.
HPOP don't fail often, its swash pump design has been in use on many hydraulic pumps, even have one in my 69 JD 140.

I don't think mine needs resealed but I'm not sure. I know the front plate isn't leaking, not sure on the valley side. Looks like I'll just keep the stock one. Thanks for helping me save money guys.

Also you could just pay the core charge and then send in your old pump for a core refund later.

Riff Raff (and I'm guessing this is being driven by TE) is not accepting pre-ship orders right now on the T500. You must send your pump in to get upgraded to a T500. They must be running low on cores.

I will add this. My truck was at 330000miles. I was laying the ground work for the big round of mods. I was making about 24-25lbs of boost after efuel got my pressure corrected. I did not monitor hpop pressure while driving to see how bad my pressure was dropping .i wish I had for sake of conversation. After the t-500 my boost number was 29-30 lbs. Mind you that's only exh,6637,efuel,50hp chip. Imo go for it. The larger output is an improvement and when higher pressure is commanded will reach the target faster.

Max pressure is only a part of the equation.

Thanks for the reply guys. While towing without a chip my hpop reaches 2871psi pretty easily at WOT. At 48% duty cycle. My boost however is still a mystery, zero boost leaks, turbos good, efuel, and I can get 15psi stock and chipped.

I got a mb diesel hpop from corey at cncfab.
It's a 17°
Happy with it so far. Probably gonna make my truck more of a smokey pig. Lol
I paid the core and I'll be sending mine back in today.
I was gonna say something else, but now I forgot.
Oh I remember.
Okay Yeah, your pump may hit x psi, but will it hold it under wot? That's what really matters.
Pump could hit 15,000 psi, doesn't mean Jack if it immediately drops to under 2000.

If your atmospheric pressure is only 12.6 psi (as posted in your other thread), then 15 psi boost is darn good.
That pump may be tired a little, but if its building the pressure that's called for, shouldn't it be ok. It's not like he's telling us that it can't keep up.
