Engine/Transmission (1998.5 - 2002) Hot Rod Vp44?

[DTroy]

Diesel Freak , where did you buy your pump?

 

[CGlickert]

Yes please do tell us. I know no one likes to trash any ones shop but this is very important to many of us and it may give the shop a chance to explain then selfs.

I would also like to know who's pump it is . How long have you had it,only heard good things about them,guys seem to say all is well,especially from Industrial Injection.

 

[Diesel Nut]

Ditto on above, I wonder who's pump you have. Brady at Industrial tells me no problem with running a comp or Drag comp. Are you running any injectors? Are you having problems with the Comp on all levels or just at the top? Does it clean up after getting boost?

I have II hot rod VP seems to idle just fine, never had it on a dyno but seat of the pants feels like there is more horsepower. Have to agree on the comp box, don't have drag comp, there is some power difference but not much. Lots of smoke with comp on.

 

[CGlickert]

It is starting to sound to me like the HR VP modification and the comp are both affecting the same thing in the VP. Which would explain why the owner does not feel the same power increase from the comp with the HR VP as they do with the stock VP.

Some dyno numbers may put this theory to rest.

Or maybe fellas trying to make high end HP may see more benafit, ie big injectors, and twins. Like AFarmer

Maybe the gain in the HR VP is added flow potintial.

I would like to here from some one who can give us the facts.

I have not yet called I. I. but I will and this tread is giving me more questions.

I will fill you guys in to what they tell me.

You guys know that a company will defend their product to the bitter end and we, fellow diesel owners, have to learn from others mistakes and help others learn from our own mistakes. I'm not in to making a $1600 mess-up. My truck has done fairly well for a 24 valve but I want 680 on straight diesel fuel and the only way to do that is a better pump. I'm just really hoping that the HRVP is the way to go.

i can say that it is not from I I. i am running injectors mach 4. 5's. sometimes it idle sounds like an old muscle car (romp romp romp romp)you know what i mean. the pump i bought second hand but i know whose shop it was from cause i called him to verify this before i paid the guy the 1000. 00. this shop is one of the best an has done alot of work for me trans(dtt)turbo ,fass,exhaust. also this guy has helped me many times in the past with problems an questions i had. i will say it is on the east coast an thats all, this guy does NOT deserve to be pointed out. i feel that it is the pump does not work well at all w/ a comp!i have talked to another person who was runnimg the same turbo an hrvp as me an he had a problem makihg power also. i am only doing 438hp an875 tq at best!(see mods in sig. below). i should be at 500+hp mark w/ no problem w/all i have. i have heard that the tst comp is the way to go when you have a hrvp. i just want to get a stock vp an keep the comp an i think my power will go up to where it should be!i get a s**t load more smoke w/ the box on but no more power an if i am getting power from it i cant tell. i even tried two of my friends comps an same result. with all this said i REGRET buying a hrvp an would never do so again. i am not saying they dont work for others but i am NOT sold on them!

I like my HRVP and I'll be getting rid of the comp box as soon as the "Smarty" comes out. Like I posted earlier not as much power increase with comp and HRVP. I think that they are trying to do the same thing and I don't like taping the pump wire anyway... .

 

[DWeiler]

That the way i'm thinking too down the road,still have my comp in the truck,not using it/untapped but my plans are to run with the mach 1. 5 /catcher and a II-hrvp when mine takes a dump. That should keep me in line with the amount of hp i want and need for towing,nothing too wild but enough to keep a smile on my face for now until i think of something else or want more.

Everyone has their own opinions, and they definitely differ on this subject.

I talked to I. I. today they said.

HP gain? 60-70 stock injectors up to 80-100 with big injectors

fuel milage? same or slightly better

bench test? yes they do for at least 2. 5hrs, every one of them

drivability? very good

life expect? same as stock

lope? yes it will most likely lope

warranty? 1 year if wire is not taped, if you tap the wire it does not cover electronics

HRVP with comp? should work well, I should see a 60-70 hp gain with my setup



If I learn more I will post it. I plan to call and talk to Schied also.

Thanks for the info,CGlickert, i want as much info as well. ---DW

 

[Diesel Nut]

If you manage to burn up a HRVP44 from II and you have tapped the pump wire they will inspect the pump for you. As long as the pump itself is ok, and only the electrinincs overheated, they will replace the electronics in the pump for you and rebench test it for you. I think the fee was in the area of $700 for this, as opposed to a full on replacement. II really looks out for their customers. Thats why I enjoy doing business with them. Talk to Brett or Brady. Call and ask, if they are available they will talk to you and answer any questions.

 

[CGlickert]

The link c-hawk posted has some good info. thanks dude

Brett was who I talked to at I. I. and yes he was very helpfull.

I think the HRVP would be a pretty neat mod, and i'd like to try one... more power from the same size injector (when compared to a standard vp), and more power without tapping the pump wire (when compared to a standard vp). And it sounds like the I. I. pump has a pretty good warranty too. But i would like to try one on my H. O 6spd which is a milder truck.



In case people didn't follow the link i posted above and read what's over there, I don't think a HRVP is worth any HP, and may even hurt (has in all the cases i've seen firsthand) when your trying to go to the extreme of what a VP truck can do.



CGlikert mentioned in his previous post, that I. I. claims 80-100hp gain with big injectors and another 60-70 hp with Comp box. Total of 140-170hp gain with comp and hrvp when using big injectors. With my stock vp i picked up 177hp just by turning on my drag comp, and that was in 104* heat. I just don't see where they are worth the money if your going to the extreme. But on a 500hp truck they would be nice because you could make that and not have to tap the wire.

I will have to call I. I. back. I think what they said is that I would gain 60-70 hp over the gain that the comp provides. But your post now makes me question that.

Mine is a drag comp so 145 + 60 = 205hp ?

I must call I. I. back.

 

[Sick Boy]

i gained a whooping 16hp :-{}

If that's the case then a HRVP, 200HP injectors and a drag comp would make for a 700hp truck on fuel???(assuming lots of air of course) stock truck makes about 190rwhp, so 390 with injectors... that plus the 100hp the HRVP should add to big injectors makes 490... plus another 205 from comp box makes 695hp.



Everyone i've seen with a HRVP and comp has results closer to Dino's then to 205hp from the comp.



I would figure the math with HRVP, 200hp injectors and drag comp to go more like: 190rwhp stock, 390hp with injectors... plus 100hp from HRVP (if that) plus 70hp from comp (if that) equals 560hp total. I think that is more inline with where a HRVP truck ends up.



I don't know... this stuff sure is interesting though.



And for what it's worth Dino tried my drag comp which works great in my truck. In his it added tons of smoke, but no power at all. Like honestly couldn't hardly notice a difference riding in the truck. However, his truck on injector only feels incredibly strong to me.

Edited to add: Someone that knows how these HRVP pumps work will hopefully chime in. I don't understand much about the how's of it at all. I'm going off of the three people i know firsthand and all they have gone through trying to make hp with a HRVP.



Maybe the guys posting to this thread with HRVP's can report there dyno numbers? I would like to see how different combinations work together to make HP.

 

[mgoncalves]

I'll post my opinion, I have a HRVP from II, I don't have a big horsepower truck by any means. The performance with my old injectors stage 3's from II with the HRVP was awesome. It was enough to convince me to sell the drag comp, and just go with a little bit bigger injectors with a boost fooler. I have the boost fooler now, and am close to getting some new edm's.



I guess my new combo will put me somehere in the 400-450 horse range, all without a wire tap box or the surge that comes with a box. I'll never know what horsepower for sure, cause my truck is retired from the dyno, but I can say that my truck will tow anything I will ever need it to at any speed I want. What more could you ask for?



HRVP worth it? Absolutely, it got me away from an inefficient box (drag comp) and gave me what I was after when I bought the truck in the first place, a nice driving, powerful, truck.
