Howdy folks,
I've got a question for all of you who have knowledge about the older 12valves with VE pump. A buddy and I just picked up a 1989 Dodge 1 ton. It has a flat bed on it, 4wd, 5spd. We're looking to build it for sled pulling. I can handle most of the stuff as far as the trucks goes for suspension and so forth, but I don't know much about the VE pumps. Is it possible to get a ve pump to turn around 4,000RPM? If so how hard is it to do. And how much power can a VE make without having to get it reworked? We're trying to do this one fairly inexpensivley. Maybe trying to find a turbo from a junkyard and redoing it. Would a Bht3b work as a single, for sled pulling only, or would the inducer be to big?

Thanks for any info you can give me,

try the 1st gen board... they've got the real info you need. I DO know that you can swap out a spring in the pump to increase rpm capability up to around 4000. Good luck... thats a nice find as far as a truck goes, by the way.

 

A VE pump is very capable of running well past 4000 rpms. With just the right amount of fuel and Timing, a 4200 rpm spring it will run up there with no problem at all. By grinding your fuel cone, grinding the AFC Foot and turning the Full fuel screw, Bigger injectors, and more air, your looking at right around 400 horsepower. IMHO, I think that the BHT3B will be a little too much to spool.

 

ok, thanks folks. How hard would it be to P-pump it? What would you's suggest for a turbo? We're trying not to have to spend very much on this, just want something to have fun with.

 

What division you're planning to compete in has a lot to do with turbo selection... HX35/ HT3B twins are much more economical than a super single, but that'll put you in a class against trucks like your's, and you'll get owned.

The P-7100 is pretty superior when it comes to sledpulling, but unless you have the pieces laying around, you can have a 14 mm head pushing 600 horsepower on your VE for close to the same price. And that way you stay true to the 1st gen roots.

I think the dynamic timing would make it sound a lot different than any sled puller with the P-pump. I don't think you'd make that "WHUP-WHUP-WHUP-WHUP" sound as you brought it up...

I've heard that a $15 governor spring will let you go up to mid-4000's, but I don't know how much power has dropped off by that point. Maybe a cam would help shift the power band. (Of course, by the time you had a cam into it you could've just got the P-pump on there...)

 

it is possible to tune a ve pump to put out enough fuel to support 500hp there are guys on here and the other website that you started this thread on . kta cummins is one of them . beagle is right about the 14mm head pump but i have read that these arent the most reliable pumps there was some problems with them in the r&d stages i dont know if kta and his partner fixed the issues or not . but he is the one behind the 625hp first gen that runs a ve pump. as for charger find you like a hx50 or something like that or a h2e they are cheap and will flow plenty of air and if you blow one up well they are cheap . you dont want to jump into a twin class with a budget truck atleast at first.

 

Found a turbo today that I think might be a possibility. Does anyone know what size an Si-50 is? Has Cummins on the badge, but I couldn't find and stamping on the rst of it for the company.

 

What class do you want to compete in? Or are you just looking for max power on a budget and don't mind being at the bottom of a particular class?

P-pump it if you want to be competitive. VE trucks are rpm limited, will only fuel to 3200rpm. Even with the bs 4200rpm springs, they will still only fuel to 3200rpm. Sure they will turn 4200rpm, but won't make any power above 3200rpm.

To p-pump it, you'll need the pump gear, front cover/housing, injection lines, injectors, fuel supply system or stock p-pump transfer pump and p-pump.

1st gens are not cheap to build as pullers. 2nd gens already have the Dana 80, NV4500 and p-pump, all of which you'll be looking for if you're building a 1st gen to be competitive and last a hook or two. Also no big input shaft upgrade available for the stock Getrag 5 speed. Also that 89 has no intercooler, so there's something else you'll want if you want to make power.
