Cummins/82 C10

Don't know Andy,probably just tear it all apart and grease it down,and keep it hid away. Like I do with everything else I think is somewhat valuable and hard for me to get ahold of. I really just am paranoid of it. If I fix the pump there's no telling what else will screw up.

The whole Idea behind having the ve on that engine (for me) is the economy and power that the advance timing capabilty provides. I don't want the damn thing sounding like its caming out,or hitting on 4 cylinders when it's idling. That just sounds like it's slowly killing the engine.....it can't be healthy for it to sound like that with a ppump puking fuel in the cylinders. No doubt it will make power,but for how long before it's pushing all the oil out the downdraft tube while it whipping out a cylinder.
idk I'm still in the undecided category with the whole situation. Part of me says park it and forget about it and the other side says fix it or sale it

[ellis93]

What's that I hear? Carbed SBC?

Issues like this would push me into a gas truck for a Sunday driver.

Nope it ain't that bad!

[Remps]

I vote 24v VE too. Run the pee pump motor till it pukes, hopefully your 24v engine is done by then. Imo, it'd increase the value of your truck as well, if you should decide to sell it.

[DMan1198]

Ve 24v is my vote as well

[ellis93]

Went ahead and bought these.

20$ worth of time sert threaded inserts to use as adapters. I also will be removing the 24v from its original truck in the next week or so to be mounted to an engine stand,converted over to a ve pump,ran and cleaned of its electrical parts/stuff I do not need. Might even give it a shot of chevy orange for good measure too

I do have to have the injectors sent off tho,and have them honed.


One question that I have that I just can't make sence of is......the pop pressures. That guy that's doing/or has done the ve powered 6.7,it has a 24v 5.9 head and injectors....in his last post on the tread,he states that the injectors pop pressures are set at 300bar and said that the pump was holding up just fine and doing well. If that's the case what actual advantage is it for him to have the pop pressures set that high?
I know it has to mess with the injection cycle and timing pretty badly,so why do it? Is he trying to combat haze or something?

" ended up putting in a stock 145 hp set of vp44 injectors set at 320bar.The pump seems to be doing just fine,the power has went up comparing them to a stock set ,set at 245bar"

[dazedandconfused]

Will the VE bolt to the stock vp44 timing cover?

[ellis93]

Nope.....vp44 bolt pattern has four mounting holes.

I have the cover/case,pump gear,and a throttle braket. Only one thing I need now and that's the trans detent cable and brackets for an a518.

Anyone care to guess?

[Remps]

I doubt he has much if any haze if he is running through a dpf and has a perfectly clean tailpipe. I don't think the higher pop pressures would be an issue, as the Bosch can make 17000 psi. My thoughts on more power with higher pop pressure are better penetration at higher boost and cylinder pressures with the 7 hole? Vp injectors. That is if 7 holers have the same disadvantages in a 24v as a 12v. Another thought, Chevy 6.5's run 2k pop pressure with a pump that can only make 5 or 6000 psi. So I don't think a couple hundred psi higher pop pressures is going to affect the lifespan of a ve, very little anyways.

[ellis93]

I hadn't thought about that. I guess then at idle w/pop pressures higher,the pump would just have to maintain higher pressure for the same idle rpm fuel demand. Makes some sence. Also explains why the 7x10s that's in this ppump motor doesn't haze at hot idle. That can't be pump differences,they wouldn't know anything but pressure was hitting the injector inlet. SOB
I'm putting this thing together

One final thought.....on the Pop psi. Couldn't that possibly shorten the injection even for the pump?

[DMan1198]

It should. With the increased delay there'd be a reduction in the cc's the pump puts out. How much though I'm not sure

[ellis93]

Yeah that's whats crossing my mind,I doubt it would mess with me much as I tend not to max out my pumps anyhow.

I think I'll pump the motor as is and run it on the floor to see how it sounds. Water hose for cooling and make a temporary intake pipe from turbo to air horn and just see how it sounds with the rebuilt pump I have sitting in a bucket for the dodge.

I'm actually excited to do it. I was dreading pulling the chevy down for this,as I know right now I'll mess up my paint pulling it down. Good thing I have extra anyhow.

As a side note.....I found another converter builder. He and I have been emailing and taking on the phone about supplying my shop with converters and as a side benefit he's going to build mine for the cost of the sunnax parts. I'll be running it and if it does well I'll be shifting all my converter needs to him.
Problem now is to pick a stall speed for an unknown engine power,4k lb truck with 3:08 rear gears. Suggestions?

[DMan1198]

I want to say 2-400 lower than stock would be what I'd go with on a quick spooling setup. I think with my 4th gen I want to go about 300rpm higher stall to better compliment my big single. With brownie I want a compound setup that'll light up in the 1400rpm range, so I'm thinking 400 lower should fit my needs

[ellis93]

My plan is/was to go with an s300 based turbo with about as tight of a housing as I could find/or look into one of those fancy hootie tootie turbos Eric has. That was before all this other bs has happened. Now it'll likely be the hx35 turned hybrid and that 24v's 9cm housing. That should spool up fast as hell but choke the motor at some point.....even with the ve's fuel capabilty I think it'll be an issue.

I was thinking 13 or 1400 but maybe 1200 or so.
