Which engine are you guys hot rodding? I was told the 12v was the best for all out mods and power. If it is the 12v, how are they better than the new 24v or 32v????

32V???

Last I checked the most valves you could fit under the valve cover of a Cummins was 24.

The 1994-1998 P pumped 12V is by far the easiest to get high HP from. The Bosch P7100 injection will move more fuel then a 24V VP44 or common rail truck could even think about.

OH sorry, My 6.0L Stroke is 32v. I guess that 4 valves time 6 cyl is only 24...my bad.

Anyways still wonder which Cummins is the one to mod

For all out HP, the 94-98 Cummins. 1500+ HP is reachable with deep enough pockets.

some beach

yup 94-98 12v will make a good deal of power so will a P-pumped 24v

go with a 24v CR..... you will find many secrets in the future. :evil:

I disagree.

While a common rail truck will move more fuel then a vp44 truck, there is no way it will move as much fuel as a P Pumped truck can.

As far as I know, the highest HP 12V trucks are running either 12 or 13mm barrels and plungers, modified P pumps used by tracotr pullers are running 14 or even 15mm barrels and plungers. But they also have a lot more cubes to work with, and 3 or 4 turbos.

I have personally seen a DT360 in a IH 666 puller make over 2000 hp with 3 turbos and a sigma pump flowing roughly 1500 cc's of fuel. Those kinds of numbers are possible with a 12V, it just takes money.

perhaps....but the Idea is surface area not volume. A full can of fuel will not ignite but an almost empty can will. I understand that ya got'a toss more fule at it and then crammmm air to it, the ratio must be there but ya still got'a atomize the fuel. .....that's why I like the CR. Wasted fuel takes up space and creates drag. Get your burn ballanced almost clean and you'll have more power.

Then again, I could be wrong. LOL

I'm gonna have to agree with Rich on this one, right now the P-pumped motors are the king, let the CR motor get played with as much as the 12V has been and I think the sky is gonna be the limit. The 12V is going to be limited by head design as much as anything, it just cannot flow the air into the cylinders as well as the CR and 24V motors can. All ANY engine is at heart is an air pump, the more efficently it can move air the better it will perform. Once people start putting the time and effort into the newer motors that has benn put into the 12V you will see a new power king IMHO Right now the 12V's rule the roost in the HP wars because the R&D has been done, 4 years ago 500HP on #2 only was almost a pipe dream, now there are daily drivers with that kind of power. Give it time Grasshopper....

Buy a Duramax, 8 cyls is better..LMAO!

I agree with billy..."dont get downhearted, i can fix it for yah sonny! wont take time...it'll just take money!"

I would just like to thank Eric for the "Best joke of the Day"! LOL

The largest nozzle size that I have heard about on an 04.5 was 0.014", which some people claimed to be too large to run with the factory rail and CP3. So if you go as far as making these injectors work, add a modified CP3 and a larger fuel rail with higher rail pressure, you only have an injector that flows about 70-80% of what the larger 12v injectors flow. Volume is important, you have to start with a large volume of fuel, and then figure out how to burn it. John Deere has had common rail injection longer than Dodge has, and I have yet to see one tractor puller change his P-pumped tractor to a common rail system. The common rail trucks will be able to make serious horsepower numbers in the future with modified CP3's, and they are awesome for their ability to provide high horsepower with efficiency and still remain streetable. But when it comes strictly to making raw horsepower, the mechanical pump will prevail in fuel volume, timing advance, and RPM advantage over the common rail.

Smoke'm, don't thay have tractor pulls in Europe? .....If they do or don't, what would or do they use? I wonder if there are any MB tractors out there?

Yes they do, some of the tractors look alot like the United States pullers http://www.tractorpulling.com/tractors%202005/prostock/Rough%20Justice%202.JPG http://www.tractorpulling.com/foto's/eurocup%20prostock/john%20deere%20etpc.jpg http://www.tractorpulling.com/tractors%202005/superstock/maximum%20risk.jpg

The Silver Valtra won the Pro Stock in 2005 - Sigma P-pump 1100hp
The White Berner John Deere won the Super Stock in 2005 - Alcohol 3200hp

....any of'em run a CR?

....any of'em run a CR?

I have yet to see any with a CR.

I have however, seen a few diesel Deere pullers running a belt driven SOHC billet aluminum head, so anything is possible, I guess.

....any of'em run a CR?

Nope, not yet.
