i have heard/read a lot of talk about the VE pump and how everyone wants to get more power out of it. i have not read much about the P pumps and know nothing about them. but it sounds to me like it would be a lot easier to convert our 1st gens over to the P pump. what is keeping you pump tech guys from switching from VE to P? as far as i know the P pump is capable of making a lot more power and pushing a lot more fuel.what advantage is there to keeping the VE?

 

The cost is the advantage. Its actually alot of work to convert to a p-pump and lots of money

 

The P-Pump conversion costs a lot, thats why not too many guys are doing it. Plus with the VE you can play with your timing, something on the P-7100 you can't do. Also I believe to get a rebuilt VE is quite a bit cheaper than a P-pump.

Front what I understand (gurus/Dave correct my misinformation ) the P-7100 is bullet proof and you don't have to worry as much about fuel lubricity since it is not lubricated by the fuel, whereas the VE is lubricated by fuel and with the new ULSD coming in, power service or the like is a must for prolonged pump life. But the reason P-7100 can build more power is because of the higher injection pressures, and like you said, ability to push more fuel.

 

Its not that pricey to do the conversion.. I don't know why more have not.. especially the VE guys.. I mean it is cheaper to replace the VE pump if you have to.. but by the time you upgrade the head and rotor on a rebuild of the pump.. your pushing the cost of a P pump.. or more... if the VE holds together.. Haisley's sells a kit for the VP trucks... but you really dont need a kit for a VE swap to a P...

 

I think the 24 valve guys have a different definition of "not that pricey" than 1st gen guys do.

If you can find a blown up donor motor to get the timing case, fuel lines, injectors, and lift pump from I guess you might do it cheap, but otherwise all those parts add up quick. If I had the opportunity to do it for the cost of just a used P7100 I'd do it in a heartbeat.

 

If I had a who running donor motor I'd probably swap the whole motor instead.

 

Who wouldn't?

 

Actually that was after watching NeedMoPower have his pump rebuilt with a new head and rotor and it take a crap.. and then he had to buy another pump because the case and most of the parts were junk inside... Ask Stomp how many pumps he's been through.. and which would have been cheaper in the beginning... I'm not saying this would be for most.. but for some...

 

A pump conversion is also unnecessary until 350-400 horsepower; if you plan on staying in that range, a VE pump is perfectly sufficient. And a lot of guys are happy at that level.

It's only above 400 horsepower that the P pump suddenly becomes a seriously needed option... It's either that or a seriously modified VE pump...

 

two words..Dynamic Timing.

 

I have been seriously thinking about the P pump. WHy do I need to change timing covers??????????

 

Because they are different . Not just the cover, but the whole timing case. Might as well do a cam upgrade since it comes out to remove the timing case. $$$

 

A while back I lost an auction on Ebay for a complete 128K mile 98 215hp 12 valve, it went for $2350. When you figure what you can sell a good running VE motor for, doing the complete swap makes more sense than ripping the front off your existing motor. That's for a 215 motor too, the pump and injectors in those are most desirable. Someone mentioned a P pump isn't necessary until 350-400 HP, there are guys making that w/ just an exhaust, exhaust housing, and a fuel plate on the 215 pump'd motors. Look at what they do w/ bigger turbos and injectors...

 

Well it all depends on your pocket book, I have been going over this for a year now, P pump or KTA 14mm rotor. I know what a p 7100 will do the sky is the limit, I would still love to ride in a truck with 14mm rotor. The only thing that worries me is will the14mm ve pump stay together? Cost about $550 to $600.00 to do the 14mm ve or $600.00 to $1200.00 just for the p pump Not includeing lines,timimg case.timing cover , piston lift pump, return lines and a hole new set of injectors. The ve has smaller lines and injector tops,theirs a good $600.00 in injectors. Just buy a 2nd gen it's cheaper.

 

2 subjects that havent come up yet.
1 Lots of us are trying to see just how much power we can get out of a VE pump. We would also like to roll up in our trucks making big numbers, then have people freak out that you still have a VE under the hood. Thats part of the fun.
2 The VE for some reason makes lots more torque than the P-pump.
Put a P and VE side by side that make equal HP and the VE will put lots more torque.
I have 2 complete P-pump set ups including front covers, 1 is even a 215 pump. Im still running the VEs.
