Competition monster VP!!!!!!

[SpicyJam]

Chris, yes this was just a same day pump change, no other adds. Silveram323 is the owner of a '01 and a half and that is what the truck netted on a dyno jet, he was high horsepower of the day cause he went and ran with the D-max crowd at Hitech Motors in Elk River, MN. He brought back the sheet to show me at the shop when he was done. I have studied all the options of the VP and without a bigger head and rotor it just is not happening. So far I have read this thread over and over as well as the thread on DTR, no where does it mention any names of who maybe making this thing, or how it is achieving the amount of fuel, I would like to some CC numbers, and what has been changed thats all and maybe a name of who is making it. April fools goes a long ways, so I am on reserve... ... I have talked to Gus on another site and we have been yacking about N2O and tires, but nothing of a VP... ..... so makes me wonder, even if you can make the VP there is nothing answered anywhere... ... ... in fact the last post about it on DTR was mid April, it is May now, and I have to think this is just not happening. Hope this helped my perspective out to you a little, if not sorry, Jim.

Spicy Jam--so it was just a pump exchange that netted this difference??? was the original VP in good working order or on it's way out?? any other things fixed between pump changes?? not trying to be a pain here, but I think it's legit to ask all pertinent questions so everyone is all on the same page---the #'s I posted above were from just a pump change and nothing more according to the originator of the info----



only a few guys know the guy who's doing the pump work and they're not talking as of yet---I only know what I've read and talking to quite of few people and digging deep, but I still don't know who is making the pump---I know it's a small shop and that there's new electronics involved--I believe the guy is doing some internal stuff that's one off stuff, but again I can't be 100% sure--- he will be found out very soon as a few of these pumps are out there in various stages and reports will come forth, but with the places selling them I have a hard time believing it's all smoke and mirrors, but we will see---it also may be that the pumps full potential isn't being seen with the trucks set up that have dyno'd---I've been given different info on how to set up the truck, so I'm leaving that for each person to talk to the vendor about--- our best bet for legit info is AFarmer and GDMRTN it seems --I should have one very soon in my hands and I'll post my findings as soon as I can legitimately back them up--but I too have some truck work to accomplish before she gets slapped in to action--I just hope it's what it seems and yes I've takin a leap of faith--been a long time since I laid my wallet on the line for something this controversial -----chris

I am hearing 650CC and new plungers.

Oo. Oo. Oo. Oo.



Let's hope this is the case.

Spicy Jam---hey no probs here--I was just wondering to make sure--and yes I understand your view as I do all others and hey it may be well founded--I for one hope not---like I said I will post my findings once I get the truck put together, but it may be awhile before it's all said and done, so I expect someone will come forth before me with info that satisfies most if not all-----chris

 

[SpicyJam]

No biggie Chris, I understood you all the way. If it is true, then so be it, if not I hate to see you guys be bummed out, as Gus could shoot himself in the foot on this if it is not true. Since he is claming to have one, and no vid, no pics, no specs, no dyno comparison, just no nothing. Don't get me wrong Gus, I still like ya, but if you are making this up, some trust fly's out the window. I still can not find any way it can be done by looking at everything BOSCH has to offer... ... ... . just not happening... ... and to have someone create a new head and rotor to move the fuel, well I doubt that will ever happen. Later guys, Jim.

 

[AFarmer]

Making it up?? Don't think so scooter. I've been cruising breaking this engine in and getting everything seated. You'll see some results soon enough I'm sure if not from me than from other people who have these pumps. They're real - very real. :-laf

 

[csutton7]

It would be a pretty good conspiracy for three separate businesses to push something that's bogus---I know that two of these companies have been running the pump since last year, which I'm sure was for testing--with 3 businesses involved in different states it's hard for me to believe that there can't be some truth to these pumps--why would anyone of them put their neck on the line for them--If they turn out to be bogus it will mean bad press, which is never fun to deal with---two of the companies I know are shops also and I can't believe they'd want the headaches involved with customers at their doorstep with a bogus product--it doesn't add up on this end just as it's hard to believe that there's someone who's figured something out---time will tell as it always does----chris



-Gus has one, but his motor is very fresh and he's putting customers first, so he's having a bear of a time trying to find time to get his truck put together to get it on the track or dyno---

 

[csutton7]

looks like Gus beat me to the punch about his truck---chris

I have spoken with a few folks from well respected shops that have seen/driven trucks with the pump. From what I understand, they make more power than a SO VP, but do not respond as well to electronics. One of the pumps in question dynoed 100HP higher than a SO with no electronics, but only made 40 more HP with a redline.

 

[Gary - K7GLD]

It's probably inevitable that experiments be done that revolve/evolve around the basic VP-44 - and pretty logical that one or more major players already involved in the VP-44/Bosch loop would be major sources for that to happen.



The issue of greater fuel flow isn't necessarily the big issue, but development of mechanical parts that provide reliability along with increased flow might be the big issue, just as it has with the already existing HRVP's.



Added to that, is the challenge of seamlessly merging the "new" VP-44's electronically into the other existing truck electronics - the PCM and ECM, as well as associated sensors.



THEN, the final goal has to be economical feasibility - can these pumps be made and sold - primarily to a limited number of competition oriented users - in enough volume to make the effort profitable?



I sure can't see some smaller home garage builder having the wide variety of resources to make it happen - and the big guys aren't about to put plans and reputations on the line until they are sure they have all the wrinkles ironed out...

Again then with a pump that cost so much so hush hush and makes a 100 over a SO? Please read what we just did with a HR pump... . that was only a pump change and 127 increase in the same day running. Still no one names who is making them, all so far is "I have spoken", I have heard", Gus I believe you have something, still don't see how it can happen. Like I said flatter me with some tech... ... ... . even you if you EDM out this and that, put in larger plungers, who is making the head and rotor? If it is with electronics... . then I know this is a farce... ... ..... because you do nothing to change the amount of fuel the pump is capable of flowing. Sorry for being so negetive about something most VP owners would like to have the ability to upgade to if they so choose, but until I see some names or some specs I doubt it is there. No one has answered one question I have asked on this thread either... . so what I am to think?

 

[RobertP]

there are a whole lot of posts on this subject and no results. come on guys with more than one of you running this thing someone can get some track and dyno numbers.

 

[getblown5.9]

i just want a dang video so i hear one idle

 

[csutton7]

so if the head/rotor have been massaged then it's feasible???



anyone have cc flow #'s for a stock vp and HRVP???



anyone know what's been done to a HRVP to make it what it is??

Only reference I've heard regarding mods done to make a HRVP is swapping of existing bores/plungers between SO and an HO pumps to provide a bit more fuel capacity - but apparently that, and use of the same standard cam followers and cam ring increases mechanical stress and reduces lifespan.



That's why I too am interested in exactly what mechanical changes might be made to produce even greater fuel output - I seriously doubt it can be done reliably without new major components such as a new cam ring, bores/plungers and cam followers - THEN there's the electronics issues mentioned earlier to phase the "new" pump in with existing electronics...

What a crowd!!! So many doubters, so many enthused bombers! Yes, the pumps are for real and if you add a box, they get mighty WICKED. I don't know what all has been changed but the stage 3 pumps are in the 600cc range. I'm still "testing" my stage 2 pump. Having a little problem getting it to idle. So far all diagnosing has proven to be my trucks electronics are at fault. Since I only work on the truck on weekends, fixing doesn't happen fast. I'd like to dyno it but egt's would reach for the sky. I don't tow but just street dragging i've seen 1650*, which I consider high. So I don't really want to cook it just yet. It will be interesting to find out how reliable it is tho. So far it has done excellent. Hope that continues. It better would for as much of my piggy bank as it took!! Time will tell... can anyone spell patience?!?

 

[csutton7]

Gary---yes that's what I've heard also about the HRVP--not much really and it's improved cc output is probably not that much more than a stock pump--30 to 40cc ---



GDMRTN---thanks for chiming in---info from someone who has one of these pumps is awesome and what we need---



I've typed about 4 pages of replies today and then deleted them cuz it wouldn't matter what I say or anyone else says if they don't have a pump or concrete info---I think the info I have received is pretty concrete, but without technical backup no one will believe it---I'm not sure we will get concrete info to satisfy a lot of guys so it's going to have to be on the dyno, race track and sledpull track that this pump does its talking------chris

 

[Dsul]

Idling problems... Does it idle too low and die or is it idling too high???

[GDMRTN]

It idles too high... sometimes. It's as if the computer is hunting for an idle. Goes between 900-1500 rpm. Mine was the first one that the pump guy had that acted like that. He's seen 1 since that did it. Something in the programming of the '99 truck doesn't digest well with the pump. Dealer reflash "will fix it"... hopefully. I've been having programming problems with truck since I have it. Maybe I should just p-pump it an run!?!

 

[Jetpilot]

What we need is a true dyno comparison between this pump and a HRVP or -27 pump. I am talking about same day, same truck, same dyno (peferably dynojet). Something with enough air that if there is additional fuel the gain will be accurate. According to all the boards several guys have the pumps but there seems to be no accurate info..... Flow numbers would be great but we need a standardized testing method for the stand. Thats one problem going on n ow with the p7100 pump, no standard for testing. One pump claims 700cc and another will test same pump and get 450cc.



I am in hopes that the pump works well and produces additional HP. We are working on some mods that will only enhance any additional fueling that may be found..... If all works as planned the more the fuel the bigger the gain!
