I think it was swamps that tried the 19* or 21*, whichever it was.. I cannot remember either.

 

someone should put a 45º in there! Single use for track only!... or could just go with common rail

 

Works just like the pumps in lawn tractors and zero turn mowers.

 

I want dual 15* HPOPs but I don't really have the money to invest in a fuel system at this time. I thought about relocating the fuel bowl, but then I started to wonder if I would be able to pull in the farm-stock class at my county fair with the duals.
I also thought about making a DIY dual set-up to save money. My school can make aluminum parts for students for alittle more than the cost of materials.
I am still undecided.

SRP1 pump at your service.

 

Swamps with the 21.
Catastrophic failures for those.

The SRp1 is running an 18.

 

I believe there is a bit more to it than just a simple coupler, but it is possible. =)

Best upgrade for our trucks if you ask me. Right up there with electric fuel.

 

Broke down is right.
XD
Broken Adrenalin.

 

1 out of the first 100 pumps ain't too bad considering...

 

Yeah. I can agree with that, but the failure itself is most amusing.

I would be super pissed having all that stuff in my motor as well.

But! The main thing to remember behind this whole situation is.

YOU decided to mod your motor.
So, who's really to blame?

The SRP1 is a pump with over sized parts and lots of modifications to create quite a good system. Which should eliminate a lot of problems like that. I would be very curious to see what actually happened and what caused it.

However, it appears something went wrong on that one, and it wasn't to pretty.

 

Sorry, it was a 20 degree swash plate from swamps.


The 19's have massive wear, which is what killed the 20's.

So I think stealth idea was lets push it slightly with an 18, and see what happens.

The bigger bores for the pistons should make for different wear and tolerances as well.

Time will tell.





I don't know if it was this thread or another thread, but somebody mentioned hooking a pump up to a motor and running it.

Its a very inaccurate test to do it that way.
You'll just see how many cycles it will last on clean motor oil with no back-pressure.

In a real world application the pump has to deal with oil contaminates such as SOOT.
Even with a Bypass, the soot is really small till it bunches up a bit. then the bypass will catch it eventually.

Different engine temperatures and such also would effect the wear of the pump.
Amount of pressure being created for x amount of time.

Ahh, you get the point.
There just isn't any good way to test one unless you have an engine dyno you can load up and run for 2 months strait.

Or say, run one with old crappy engine oil.


I guess this is a good time to point out yet again that our OCI's are so very important.

 

That was me and I fail to see why setting up a test bench properly would not properly test the pump. A load on a pump is a load on a pump. It doesn't know or care if it's a test bench or a truck. Load it and let it run.
Run good oil or bad, whatever, I think it would work instead of waiting 2 or 3 years running them in different trucks.

There's no substitute for real world application testing, but a duration lab test would be hugely beneficial as well.

 

yeah, if you can load it, then it would make a great difference,
but you'd have to test the pump with used oil IMO.

Slightly used, not 3k+ oil.
That way its more "realistic"

Just like the tests that bosh did with fuel pumps.
Seems bout the biggest load of bull from what they tested, cause nobodies truck would be running. They just ran fuel though a pump for x hours and had catastrophic pump failures.

I do believe Joey tests his products in his own stuff before making it available for anyone else to test, but I am unsure on this.
As for what Stealth does, I only have rumors.
I cannot say the SRP1 is a bad idea though.
It's a better idea than throwing a big swash plate in a pump cobbled together with used parts though.
Your at least getting an engineered product with new parts in it.

=)

 

Don't forget Gary has the Stealth Stage-2 and Stage-3 pumps out for what, 3 years now, and those were 100% scratch built.
He knows what he's doing with these pumps.

 

Yeah, stealth definitely knows what they are doing with these pumps... No room to bash their stuff. Not sure why the adrenaline was brought up and bashed on AGAIN either.
