HPOP Question

[bryceba]

I have the mods done that are in my sig. I just ordered a dp with th 80 tow, 80econ, and the 140. I have read that I may have hesitation with the 140 because my HPOP cant keep up. first of all, is this true? Second, will it cause damage if i run it? And third if I do have that hesitation what is the cheapest solution. I have some other stuff I have to put my money towards now, (something about being responsible or some crap like that)? Is there such a thing as just a new HPOP with a higher pressure or an upgrade or something?

hpop's hardly ever wear out, usually the IPR will go bad first. And to answer your question, yes, your hpop may have issues keeping up with the 140. The 120 shouldn't (SHOULDN'T) give you problems with the 17* pump.

to keep this on the home page. I am not certian. so ill let someone who knows more answere.

[bryceba]

so is there any solution to fix it without spending 2 grand

[4everlearning]

adding another hpop and running duells

[bryceba]

how much is that?

Short answer, no. There are new single HPOP "big oil" setups coming out or on the market now. If I were to go to a single HPOP (which I wouldn't at this point), I like the pulse unit by Bob Reilly at dieselsite. I would get a DIY big oil and get another 17 or 15 degree pump. You will be able to find a 15* pump cheaper and will be able to supply all the oil your injectors need.

But I would go ahead and get the 140 setting if you want. You may not have any problems. Remember that each truck is different and we can only give you guide lines. If you told me you had larger injectors.. then your only choice is going with big oil. Either way you look at it.. you have to pay to play.

Haha I hear that dirk. Unfortunately my little lady doesnt haha. So what do you thin it would cost and what is involved in doing the dual setup

[Dirk]

Hard to say. DIY kit will run you $600-1000 depending. You will need to shop around, maybe you can find a used one (not likely). Then find a 15 or 17 pump. I stole a 17* pump for 150 shipped.

This is what I did...

Think about your final goal.. where you want to be at the end. Write out everything you will need to get there. This will take A LOT of reading and studying up on the metric f*** ton of info on this site. Once you get a good understanding, build the foundation. Exhaust? Check. Intake? Check. Gauges? Check. And so on...

Remember that the 7.3 lives and dies by the HPOP. If you don't have 2600+ psi pushing the injectors, you may or may not be getting all the fuel into the cylinders. When you start messing with a high output chip (or injectors), you change the whole game.

If you are second guessing the decision of getting a 140 tune, I would go to the 120.

Just my 2 cents.

EDIT: Don't forgot to buy a overboost annihilator. I like the ITP one. Get it from Dennis at ITP or Jody at DP-Tuner.

Well if it runs good i am fine with it. Would a fuel pressure gauge be something worth getting. Would that shed some light on the situation of wether i need the second hpop?
