Wow, the oil pump has stirred up quite the convo lol
good ole' trusted LOL
The question is, was anyone actually measuring the ICP at both the rails and the pump to see if there was any actual pressure drop in the system?
When talking with Bob about this subject today, he indicated that when he had done initial testing on the system on an otherwise stock(ish) truck, the HPO rails would show a reasonable pressure but the HPOP would be hundreds of PSI higher.
Again, it comes down to a very simple test. Two ICP sensors... One at the HPOP and one in the head. If the delivery system is not a concern, then there should be pretty close to ZERO pressure difference between sensors. Being able to test under different conditions such as varying loads and power levels will help to shed light on just where any deficiencies are. All it takes is time, and a $135 sensor. Well worth the investment to put this issue to bed.
On Edit:
Just got off the phone with Bob and he confirmed that Tim DID have the HPODS system installed on Deranged at the same time he installed his Adrenaline HPOP. In fact, when they first started the truck and realized (much too late) that the had an oil filter problem on the truck which caused him to have to tear down the engine, he had the HPODS and Adrenaline installed because he had to send it all back to be to be rebuilt to remover the filter debris.
Well, at 285K miles, I'd say it's a strong possibility. :shrug:
lol at least my good 'ol trusted 64/71/70 charger is still holding strong.
Sorry bud...i stand corrected then. Never heard Tim mentioning that he also had the HPODS on it...only heard him mentioning the adrenaline pump. Thanks for the correction.
But on a side note....I have an early '04(basicly an '03), and Bob does offer a billet high output adrenaline for the '03-'04 models, but no HPODS. Now he said that the HPODS needs/should be used with the adrenaline pump. So why sell a billet adrenaline pump for the '03-'04 trucks if you don't have a HPODS for it that he recommends? I know the '03-04 trucks don't have the ports/plugs in the rails like the 2004/5-2007 trucks do for the HPODS to work on the early model 6L's, but still....why offer a billet HPOP and not the HPODS for it if it's recommended? Just doesn't make sense. I wouldn't mind putting a HPODS on my truck if it's really gonna make a difference, but Bob doesn't have one for '03-'04's. So i guess there really isn't any reason to even bother installing a billet adrenaline HPOP either the way it looks.
Yea it definitely is. I am sorry for the vague question. I was more referring to what it was exactly you were looking to prove/solve with basically a stock pump?? Nevertheless, if you have to replace it, you might as well do it right and Bob's pump is the best way to do it IMO.
I'm excited to see your results for sure.
What he said.Not trying to talk for Bill but IIRC I remember him mentioning doing that in his test. He fully intends to put a guage on the pump and another one at the end on the rail and see what is what exactly because you are completely right.
I remember him saying it was goin to provide thhat info but no one has seen it yet.
There is obviously much more going on with the HPO system than meets the eye and I intend to get to the bottom of it and find out, once-and-for-all, exactly what's what. Since we have the ability to not only monitor multiple sensors, but to also high-speed datalog, we can see just how much proximity to the pump affects the sensor or even if changing the sensor location makes any difference in the overall performance of the vehicle (as some have indicated it does). Lots of options to try and test. I'm already making a checklist of test procedures and conditions so that I can make sure not to leave any combination out. Unfortunately, I don't have the cabbage to spring on an HPODS just yet, but definitely have it on the list of goodies for the truck
In any event, the next couple weeks are going to be interesting!
Now if you say the factory delivery system can not flow what the pump puts out. Can you please post the supporting data to prove that. Put a pressure gauge at the pump and a gauge at the end of the oil rail and see what the pressure drop is. If you have the same pressure at both gauges then the factory oil delivery system works fine. If you have 4000psi at the pump and 2500 at the end of the oil rail then I'll believe the oil delivery system isn't big enough. Until you show and prove that data. The riley fancy delivery system is nothing more than internet hype
