Everyone is throwing p-pumps on their 24V's but has anyone done the reverse?(I know that answer to that one)

But before you laugh, VP's aren't THAT bad, if you get a good one and have lots of cool fuel. Push button controll is nice. How would the engine act having 12 less valves?

 

What possible advantages are there? I'm not being funny, I really don't know. What's push button control?

As far as I know, the vp can't do anything better than the p pump, and does most things worse. Meaning, longevity, reliability, etc. I don't think the vp makes better power either.

 

Are you seriously insane???? Why would anyone take off a million mile pump and put on a piece of junk like that?

And fyi, I do own a 24V and a 12V

 

there is a $100 bill on my vp44, come get it take the comp too and leave the p pump in its place, I'll take care of the lines myself.

 

 

Plus the 12v head does not breathe as well.

No upside to the swap.

 

Just curious... By push button controll I mean you push a button to adjust performance instead of wrenching.

 

No, we have the performance control at our right foot. No need for pushing buttons.

 

That is not always a true statement. The reason that I say this is because eletronics will fail ..period. My wife's truck has a FASS system,1/2" Aeroquip lines feeding the 44 when the never seen less that 12lbs of pressure even on hard runs. One day out of nowhere and without warning..the truck up and died. After we pulled the codes..it was a dead pump. No amount of cool fuel in the world is going to keep it from dying when the electronics give it up...

Yeah ok...let's just let this thread die

Is dead on!!! There seems to be this misconception that a good supply of fuel is the cure-all to the VP however both the ones I had fail had no issues with fuel supply, and died from electronic failure. Just from my observations and experience electronic failures are more common than mechanical so the guys that get ones that last should buy lotto tickets IMO. The VP was also a dog for fueling (very slow to react to peddle position) however the Smarty wasnt arround when I had mine.

 

I know the electronics are turds, and I've been through my share of them. There are trucks making 800+ with them. There's been another upgrade to their circuit board lately too, if it fails I'll let everyone know about it If a p-pump has better pedal response, I need to drive one because my 44 is pretty tight, better than any gasser I've ever driven FWIW. This was a dumb post and I sucked a lot of intelligence out the board :duh:

 

Not necessarialy. You had an idea, it just turned out to not be a very good one. Nothing wrong with that. Wou wondered about something, and now you know the answer. Or at least what we think the answer is.

 

IIRC, Cummins had an ISB 12v for some Ag/Industrial applications. I seem to remember something about it on Cummins website!

It would really be a sweet little setup in a clod climate, where it needed to start really well...and at ~215-230hp MAX, and 12v head flows fine

I used this engine for skid testing and the way we knew these VP-pumped (mechaincal - not electronic) 12V engines were due for repalcement was when the pump would fail....(usually 4-6,000 hours)
