Has anyone tried this pump? It seems reasonably priced for what you get.

 

I'd check this out... LOTS of info.

Oh man haha i learned my lesson on that thread, i opened a can of worms on that one lol. And is/wasnt claying testing one of those pumps out or was that another pump he was testing out? i guess they are pretty knew so not a whole lot of info on them.

 

Blake, if you hadn't asked that question, someone else would have! I learned a lot in that 10 page thread

 

Clay is testing the Terminator T1... Phil, the SRP1 seems to be a good pump. It hasn't been out long so who knows what the reliability is like, but Stealth seems to make nice pumps, so I wouldn't worry much about it. I have not spoken with anyone who has had their hands on an SRP1 though..

 

The T1 test unit has moved on. It is somewhere in Northern California IIRC.

 

That is correct, we swapped it on to a truck in Yuba City. I already put 11,000 miles on it and have done all the testing needed for Stage 2 injectors. We are now testing on AD injectors and looking for 25,000 miles. Currently the pump is holding 3100-3150 psi at 48% Duty Cycle on the AD injectors.

Here is what anyone with a 15* HPOP needs to convert to a modded 17*. As usual Joey has our back and keeps coming up with what we need at an awesome price. This thing is even making slightly more volume than a standard modded 17*.

Riffraff Diesel: NEW* Terminator Modded 17*

As far as the SRP1 I think there is a thread in the Super Duty section where someone just had theirs blow up after about 50 miles.

 

That will take forever to test the T1.
Joey should rig it up to an electric motor and let her run full bore for a few months then examine the internals.

 

I'm actually sending out my pump in thE next day or so to Joey to try th new awash plates he had made, I can let you guys know how it I when I get it back next week if you want?

 

On this topic... does anyone have a cut away (or exploded view) image of a HPOP so we can see what is going on in there? I know what the HPOP does, and where it get's it's power from, but how does it work?

 

I use to have an animation of the pump working but can't find it. Anyway here is a breakdown view what it looks like inside ...

 

Swash Plate Pump (from Internet Glossary of Pumps)

 

Good animation! My understanding is that the difference between the 15* and 17* pumps is the angle of the swash plate (little ramp) on the left side of the animation. Obviously a 17* pump will pump oil at a higher pressure, and depending on the bore of the cylinders, pump more oil. It makes things a lot easier to understand if you can see how they work.

 

Ah thanks Jim and Chase! Tried to rep you both but in jail still...

OK, so the 15º vs 17º angle is the measurement of the stationary swash plate to the rotating cylinder?

EDIT Nate, you beat me to it. Thanks!

Very true. written descriptions only get you so far. I'm betting the majority of us here are visual learners anyways... I know I am.

 

Yes the degrees of the pump is determined by swash plate angle. Higher angle = longer stroke of the pistons = higher volume of oil. It also means increased wear though. Years back someone (Stealth maybe?) tried a 19° or 21° pump (they say memory is the first thing to go...) and the longevity just wasn't there.
