Competition Vp44 To A P7100?

[pro99]

I know that it's not easy but I want to convert my vp44 to a p-pump or should I just buy a 12-valve motor with the pump on it and swap it in place of my 24-valve motor? Does someone have a list of parts or a detailed step by step to perform this task? I have a stock p-pump already but what to do?



I can't wait to see this

Haisley machine has a kit to convert vp44 to a p-pump. Im not for sure of the price but i think it is around 1,400. 00 but it has every nut and bolt that you will need to convert it over

Chaz..... sounds like a lot of work LOL



just let me know if you need a hand



if you are getting rid of your VP let me know on a price, i would like to have a spare just incase.

I have a buddy who has 2 p-pumped 24 valves and loves them. One was done by piers and the other by diesel dynamics. Not sure of the details but I understand there is a bit of work involved. I love p-pumps, nothing between you and the fuel but your foot!

 

[Mhannink]

well i got a buddy working on the parts for one i belive he is doing a new cam the pump(duh) costume injector lines and reset injectors for about the price of a hrvp44 he was over last i checked but not by much. not so much that it seemed not worth it for what your getting. pm if you have any questions and ill shoot them over to him and see what i get feel free to ask

protwin why convert? Unless it was for just pulling I dont really see the benifits of the p-pump. The vp is wayy more streetable. I have thought of the swap too, but there were not enough benifits.

I came across a thread the other day and read about this. I think you need to change the front engine cover, as the hole for the pump is probably bigger diameter. You will need the pump (you have) injector lines to the injectors and the miscellanous lines/hoses from filter and return lines. You may need the pump gear, if the nose of the pumps are different.

Protwin, i just got the conversion kit from haisley this weeken to convert my vp to p-pump. I have to say that there is alot of work to convert it. There are boxes and boxes of bolts, nuts and brackets that you have to switch over. It is going to be one HE!! of a job, i hope that its going to be worth it. Scott

There is a complete p-pumped 24 valve motor for sale over on the nwbombers site.

WHY, The Vp 44 will make more power then you have truck. The abilitys of the Vp pump to make real usable power and have a true timing curve. On a full race only or pulling only truck the p pump is the was to go , that is until the cummins CR is cracked like a duramax with programs like EFI live. build something for you true use , and be honest about you real driving habits

Project X diesel makes big power , with almost no bad manors, a 860 + hp P pump truck is almost impossible to live with

PREACH ON, BROTHER!



Run of the mill guys having trucks that are normally only street driven with mods in the 400-500 HP range wanting primarily to dump that hated $%#& VP-44 - or because they expect some sort of power/performance advantage, are likely kidding themselves!



The cost and associated effort to make the swap from a VP-44 to a P7100 is pretty extreme - and not for guys with limited $$$ or mechanical/tuning skills.



I will be interested to see how many guys doing - or paying someone else to do it for them - the swap, will be returning here with followup problems, complaints and questions - like in THIS thread:

Thing is, you don't usually hear the downside, until someone pops up asking questions like the original poster in that thread - THEN you find that a number of other guys have been having the same issues - but kept quiet about them...

How many vp-44's would you guys replace before you decided to go with the more reliable P7100? Go ahead, tell me about your brothers uncles cousins sisters truck that has 400,000 miles on the original pump and I'll show you hundreds that didn't make it to 100,000. Also you mentioned how much power you can get from the VP, your right but what did it cost you to get there. Take a vp and add 120hp and take a P and do the same and tell me which was cheaper. Some people have good luck with their VP others don't. Some people can break and anvil with a rubber mallet. CEstep since you already have the pump (the biggest expense) you could probably sell any electronics you have to offset the cost of the conversion.

I agree. When I did my first vp to p-pump conv,I sold my HR vp44 and my electronics and some other stuff and paid for almost everything includeing a new stupid pump. And the truck was much better to handle at 750 HP. the only thing nice about the vp was it could be turned down,but who the heck wants to turn it down???But remember Im the kind of guy who trys to drive a full blown pulling truck on the street not the kind of guy who trys to pull a street truck.

Pump flutter(in neutral nontheless) is hardly a dead Vp :-laf I know you Have a better arguement than that. Remember, this is the Competiton Forum, not the tech forum. Most of the folks who run p pumps on anything and make decent power have pretty good mechanical and tuning skills... ... or lots of $$ Then again, most of the folks making big power on a VP pump do as well.

 

[Gary - K7GLD]

Very true - but ordinary users are not barred from reading here, and tend to base notions on what they read - and then put those notions into practice - and not always for strip or track use...



Nothing wrong with P7100/VP-44 swap discussions, as long as a solid grip on reality is maintained, as well as the caution that swapping in a P7100 by guys using trucks only for street use JUST to replace the VP-44 he has become disillusioned with MIGHT not be the most cost effective way to go...



It might be well for street-driven truck owners to realize that the largest group of users of P7100 t0 VP-44 swappers are quite likely Competition enthusiasts - and that what works acceptably on dragstrips and sledpulls MIGHT not be exactly what they want in a daily driver, either...

I bet you get some funny looks when you raise the body on your truck to get out at the grocery store.

Yea-but take the front drive shaft out throw a 1600 pro-fab gear in and it does John Force style burn-outs in town!!!!!!!!I wonder if I can spin a mod truck around in front of the hotels at IRP this year?
