upgrade to the newer oil rails....

Pizza pig · Nov 6, 2012

04.5 wavy rail setup still uses the 03 style pump, so you can still use the 03 adrenaline but get the benefits of the 05 delivery system.

Morgan@Midwest Diesel & Auto · Nov 6, 2012

I understand the need for better oil delivery and the restrictions involved. But I was just wondering how much net hp was gained by relieving the restrictions and letting the injectors get the right amount of oil? I know the gain would be higher the bigger the sticks were, but what was the hp gain you had over the stock oiling route.

Either way the lines and kit are a good idea for anyone who runs their truck hard.

So to put new rails on a 2003 what would you need? I would think rails,valve covers and stand pipes. Would that work with the 03 branch tube?

I read somewhere that the 06's had the best oil rails for flow and supported bigger injectors then the other years. Does anybody input on this and the effect it has? Are the 06 models less prone to pressure drop?

That's what I heard as well, though going from 03 hpo system to the newer style requires changing a lot.

I ran Bob's Adrenaline pump on my '03 engine that I changed everything to run the newer wavey rails, but the old style pump. It ran 225/100's but the Autometer gauge was tied into the ICP line wires, and showed pressure dropped down to 2100-2300 psi.

Rebuilt the engine, ran the exact same setup, but changed to the new style stock hpop ('05+) and the truck would fall on it's face every time I got a little past half throttle.

How did it do (sotp) with the Dieselsite pump?

Ivan did you have ipr duty cycle pulled in your tune? If not thats probaby why you couldnt hold icp

TooMuch03 · Nov 8, 2012

Did you ever run it with the straight rails? Maybe I am missing something, but I would think that straight rails would flow slightly better, assuming the same cross-sectional area? I thought the only reason they switched to the wavy rails is because it was quieter?

I could not tell that it was dropping pressure...hell, I thought it ran good...but the gauge told me otherwise.
When I switched to the stock '05+ HPOP, the difference was night and day. (Running the same 225/100 injectors)
I thought I had multiple HPO leaks, but the engine started up hot or cold, no problem...turns out, it was just needing more oil.

No idea. Eric knew what I had at the time.

No...the straight rails are half the volume of the wavey rails. 15cc compared to 30cc.
With increased volume, it should hold the pressure longer before dropping off.

My biggest concern about the HPODS is that the pump can only move so much oil through the outlet hole of the pump itself...no matter how many more hoses you put on the outlet...it can only deliver so much oil.
Now...add another pump, along with the HPODS, and all your HPO issues go away.

i havent seen or heard of anyone that knew enough to pull ipr duty cycle in tuning for that pump...

when i was data logging i actually stumbled on it by accident...

I guess I am just slow, but I am not understanding how the volume makes a difference. I was under the impression that flow was more important than pressure in the oil rails? Can someone explain this a little further?

the cc of the rails wont cause the system to hold,or not hold pressure.

restrictions in the system,pump size, and injector oil consumption,will determine how much pressure you will have, or not have...

Another reason why I'd like mine live tuned by someone.

Thing of a garden hose. At 50pis a 5/8" hose flows x amount of water. A 3/4" hose flows x*2 amount of water. (Not exact math but the volume allows more flow and less restriction.

So how do we early 03 guys get it? Convert the oil system and rails to 05-07?

That's what I did.
Need the rocker boxes, glow plug harness, valve covers, etc.
Just find someone who is parting out an entire engine, and buy the whole hpo system...easy.

Thank ya sir :thumbsup:

Just out of curiosity how do you convert voltage to icp pressure? I have the kit sitting on my shop bench but have not installed it yet. I am running 205/75s so hope once i get the other issues worked out to get some more data
