Engine/Transmission (1998.5 - 2002) High perf. VP-44s

[Rebel Ram]

I am doing some research on the "Hotrod" Pumps out there and I am not sure but am I correct in the conclusion that these are fine pumps and are a good thing, But aren't the only changes in the Electronics of the Pump and that there aren't any Mechanical differences. So the advantages to these pumps can be had by Boxes & or Tuning Programmers? (i. e. Reflashing ECM)

I really don't know the answer to this so if there is a superior mechanical version I would like to know. And rather than taking the word of venders or there customer service sales people I put this question here where there isn't a buck to be made.

I know the electronics are updated as far as the mechanical part I really dont know. All the mechanical stuff is brand new though. I would not get this pump unless you are going to throw some good bombs at it ie: FASS or RASP, Injectors, boxes, transmission or clutch, exhaust, turbo etc... I have one one my truck and love it! Get ready for a choppy idle (which sounds pretty cool) and a little surge going down hill with the cruise engaged other than that it is a great pump.



Spill out your plan and see if some others can steer you right. I am kinda new to the cummins world, plus I am a GM technician so I might not be able to do to much path building for you.



Good luck,

Sean

I think you're getting more volume out of the hotrod pumps by combining the longer stroke of the HO pump with the larger pistons in the SO pump.

 

[elandon1201]

From what I hear they use the SO and HO components in combination. All I know is I put one on about a month ago and I am very happy with it. Just waiting on my DTT trans. to come in so I can hook the comp back up and maybe upgrade the injectors.

It's more involved than that. We not only use a lot of new parts that we make a SHO VP44. We use new PSG's, Head & Rotors, Pump housings, etc. Our pumps are as close to new as we can make. But the latest reason our pumps are the best is we now have a new updated PSG (Brain Box) Better than the FedEx PSG. We are always looking to make our pumps as trouble free as can be made. Thanks, Brady

 

[elandon1201]

How long has that been out Brady? I got mine from you about a month ago, does it have this computer?

 

[BradyWilliams]

Just barely received them 1 week ago. I had no heads up on it sooner. We ordered them as soon as we had the chance to get them. We should have been the first to start using them. Thanks

Brady, i was wondering did i i get the new computer put on my pump. I s the new computer suspose to be better, live LONGER or make more power... Scott Fulrath

I was just starting to do some of this same research. I've got a chance to get a deal on a very slightly used Hotrod VP and want to make sure it will work well with the rest of my plans. The truck is stock for now except what you see in my sig. I'd be adding the Hotrod VP first and working from there as the budget allows. I'm thinking of adding a MAD Smarty programmer, injectors, Edge Comp FASS, and DTT full transmission. Not in that order of course, more likely the VP and FASS then smarty, trans, comp, injectors. Of course this is all subject to change, there isn't much new tech coming out for my truck now but there's always that possibility. I use the truck for daily driving, a little light towing here and there (just a tool trailer or a car on a flatbed) and I'm thinking of going to the dragstrip with it eventually.

Yes these are good pumps with very few mods but what happens when you push it to the limit with mach BIG injectors and twins and big HP boxes. noone know and if they do know then they won't tell so there is some things that we need to know about these pumps

 

[elandon1201]

Bad DNA I think the HRVP will hold up fine with that setup as you can see by my sig I am pretty close to the same with my DTT coming very soon and this pump gives you plenty of fuel I love it.

"I'm thinking of adding a MAD Smarty programmer, injectors, Edge Comp FASS, and DTT full transmission"



i would go a TST or bluechip instead of the comp stacked with the smarty.



my question is whos got a no-strings warranty on their HRVP if the pump wires tapped? have heard different stories of people not receiving warranty coverage with a tapped wire.

 

[elandon1201]

I dont know. I am still afraid to tap mine and dont know if I will.

Yup - my usual luck one more time - I just got my backup/spare delivered from II last week - just before the latest "new and improved" electronics hit the bench... :{

:-laf Gary, why do I picture you crying about getting an "unproven" pump if you had ended up with a new one :-laf

SHHHhhhhhh!



That was the only consolation I had when I found I had missed out! :-laf :-laf

Unhappy Hot rod vp44 experience this month

Rebel Ram,



My II hot rod vp44 has idled and behaved in what I would say an uncivilized manner since the first day it was installed Jan 1st. . With mach 1. 6's and an Edge comp set at 1x3 or turned off it lopes and idles irregularly at stoplights.



I have an '01 auto and when put into gear it can be a damn embarrassing experience with the loping and buck that occurs until the pedal is throttled for takeoff.



Was $1700 well spent by a guy who tows trailers and does not race, dyno or pull? The answer is no. Do I have a bad one? Who knows. I am starting to feel the warranty from Industrial is a pat on the back after two phone calls stating this had not been right since it was installed by one of their distributors. My truck idled fine with the dying injector pump until I added the Hotrod Vp44 inorder to circumvent a potential catastrophic breakdown while pulling horses to Florida.



Ask yourself and II these questions before you buy a High$$ VP44, will it idle smooth for me? Will it be quieter? Does it make the diesel fire like it has an aggressive cam. Should I only add certain injectors for this product to perform in a civilized fashion. I. E twising, shaking and shuddering while hold all of these forces back with the brake till the light turns green.



The above happens to some buyers (this word is out) and in fairness not to all . The HO vp44 might be the answer for the track and pullers, but the Hot Rod VP 44 from Industrial has yet to make me a happy tower.



I was told to drive mine a few miles and give it some time to settle in and see if things work out. 1 month and 3 thousand miles they have not.



Should I get this one replaced, could this be a bad injector or is this just the way the great Hot Rod vp44 performs? Maybe if I bought from Target or Home Depot. That would make for an easy exchange. mine is now used and is worth nothing more than probably a core deposit. Everyone points fingers and says "what can I do for you" in a meaningless way.



All I can say is mine loped and cammed like a gasser the first moment I drove toward home from the install at Performance Diesel Wharehouse. Doug the Owner/Distributor and installer even commented on the rough idle when he handed my keys.



Folks check your warranties and spend your dollars as wisely as possible. 50 years and I still am gittin bit in the ***. I believe the "TDR" motto " I am my own warranty station" goes right alongside with the vendor purchase.



After dropping $4k on rough running bombs, At least feel my pain!!

First, if you have not clipped the pump wire then we will take it back. You are talking about fairness, what have you done for diagnostics? Did you try some smaller injectors? Did you call your injector supplier and tell him his injectors are causing a problem? I see you are running a Edge comp. How did you connect it? Have you called Edge and complained? We install these pumps here all the time. We run these pumps on our own trucks. We have never had the problem that you have. The last time we talked, you were going to check out some things and try some smaller injectors. You have not talked to me since. You talk of fairness but then you slam us and our products before anything is checked out. You have not sent the pump back to us to check it out and see what we can do for you. And you say we have no customer service or warranty. You are our customer, we do care about you. If you want help you know what you must do. This post is certainly not fair!

Right on..Industrial Injection

Brett, I am glad you set this straight. I believe, your warranty is for one year, and also states if you tap the PSG wire, your warranty is "VOIDED". I have had a couple of HR VP-44 pumps on my old 2001. I have used 8 different injectors on that truck and they have a major impact on the idle from real rough ( like a heavy cam in a gaser) to smooth as a kitten.



Industrial Injection, builds the best HR Vp-44's, turbo's etc. in the west or any other parts of the country as far as I'm concern. They use only genuine BOSH parts, and construct these pumps, including OEM replacements with the up-most care and procission. Do I work for them no! Am I being endorsed or compensated by them in any way no. I am lucky enough to live in the same area as Industrial Injection, and have spent many hours with Brett and Brady at their shop watching and learning. Being a certified BOSH service and testing facilities along with others, nothing goes out the door without Brett or Brady's approval.





Do I feel sorry for you NO. If you guys keep screwing with the electronics on these things, one day I wouldn't be surprised if Industrial Injection stop making and selling these things like some other vendors have. Does stacking, packing and tapping make you smarter then the builder, I think not! Do your homework before you build your truck to your desired HP and performance levels, and get the proven recipes. Don't bake a cake and complain it tastes like a cherry pie because you didn't follow the right recipes.

"I'm thinking of adding a MAD Smarty programmer, injectors, Edge Comp FASS, and DTT full transmission"



i would go a TST or bluechip instead of the comp stacked with the smarty.



my question is whos got a no-strings warranty on their HRVP if the pump wires tapped? have heard different stories of people not receiving warranty coverage with a tapped wire.

So are you saying TST/Bluechip + Smarty? Or is that TST/Bluechip in place of both the Comp and the Smarty?



Also, how is drivability for those with both the MAD programming and a HRVP44? If each on their own make the truck more responsive I imagine the two combined might make it pretty damn twitchy.
