Diesel Lady,

I'm sure some of the electronic gremlins, are casued by climate. But why take a chance?

I guess I should have known that this was one of those hotly debated topics... . :-laf :-laf :-laf



Oh well... whatcha gonna do.

I believe that the 12v can have the "53 block" crack to so it is NOT just the VPed trucks for coolant leaks. Drive a couple of them and buy what you like the interiors are different and the drivability is different to each there own.

Ok, so the prices are about the same. Not to deviate to much, but the EGTs can't be nearly as low as a CR at that same HP with stock turbo.



As far as Torque. The CR's have a long bigger range of slightly less torque. the VP's DROP like a rock once they peek. Top end wise, that's where the CR's shine.



totally different approaches to diesel power bands that's for sure. As far as which is better, I'd chalk it up to personal preference, I like my 1800-3200 band of HP and torque.

Well your also talking 2 different turbos. Of course the EGT's are going to be different, although... I know STOCK the CR engines can run on the hot side towing.



You call 200-300lbs slightly less? Come on, Mustang GT's are lucky to SEE that much torque! The last time I dyno'ed I was at 324. 9hp and 1016tq Your at 460 and 860. If I was running a 913 pump with the same mods I have now, I'd be well beyond that.



1800-3200rpm, not bad,but I'm actually at around 1600rpm all the way up to3800rpm. And I haven't installed the last spring of my 4k GSK.



The 2 different engines with 2 different fueling curves, that is for sure. Of course this debate was the VP and the P7100, so I don't know where your CR engine came into play... .

I was pointing out the CR trucks have cheap easy good power with a box vs all the work a mechanical truck needs.



As for my 860. That's gota be much higher now as I've had that stupid juice box updated with some fixes. I can make some massive low end smoke compared to pre-fixes now, I'm sure that means more torque right?



Do be surprised to see 500hp and 1000# give or take a few here and there at the next time I dyno with stock turbo. I plan to take an hour to dyno at hi-tech once Winter fuel is outa the mix and it's near 70 degrees out.



What is your torque and HP at 2500-3200rpm and then up to your redline? it's no where near 1000#'s is it?



The reason I say 1800+ for my truck, is that when the tires typicaly break lose at 1800 in 3rd.



As for towing hot, I've never had more then 7000#'s behind me, didn't get to bad. Tho, the CR's run hot by design.

What you pointed out, was not what was asked.

I'm just as bad, for replying to your improper answer...

Why is it everyone thinks that with just a box they can break 500hp with a CR?

You've got your box, now it's time to get dirty to break that 500 mark. OH ya... and expensive.

While I am more intent on watching my daughter right now than try to dig up an OLD dyno graph, I did find one of Jim Fullmers.

Sure the torque drops off, but pulls hard right past 3300rpm where it finally stops MAXING the dyno. He also didn't start the run till about 2200rpm.

Your right. I was merely taking a jab for easy cheap box power. And 500's the limit with out breaking things for the most part.

So the war goes on. The only pump I had any trouble with was my 93, which my son now owns,he has 235,000 on it now. The problem was back around the 120,000 mark. My 98 12 valve, no engine problems at 182,000. For all the 12 valve guys, IT IS FOR SALE!!! Add no. 19691 in classified. My 2001, 1 lift pump failed-213,000. My 04. 5, nothing yet at 46,000 which is by far the best driveing of them all.

Well, OK, I hear ya.



My quandry is, for a tow rig, I'm a bit hesitant on 12V trucks because they're old enough that other stuff is falling apart or beat to hell.



So I'd feel a bit better with a truck <10 years old. Is the p-pump conversion of a 24V worth the work/cost?



I imagine Sleddy saying "just yank the whole thing. "



Is the reliability of the VP44 really that bad, if fed properly with a good lift pump? I don't hear public outcry about them... .

My '01 has 290K on it now. I'm not the original owner, but have had no power related issues - just a water pump and some other "normal" stuff that wears out given the mileage.



I still prefer 12Vs though...

This graph looks a little better, still late on the N20
