I'd be up for that! Not sure if I'll make Columbus or not yet...



I'll let you know if I do. I don't really trust the timing pin too much anyway.

well since this started out about different pumps......

I was looking around the internet and found this picture saying, with a saying right next to it that said... .



"the use of a 12 cylinder pump on a 6 cylinder diesel tractor pulling engine. "



#ad






could this, or something like it, be done with the 5. 9B?



Wondering,

Timing Light

To use the light, you need an accurate TDC mark on your balancer and a stationary pointer (just like on a "gasser").

The pickup goes around #1 injector line and is connected to the amplifier box. The amp. fires the light and you "adjust" the box until the balancer mark and the pointer line up, then you read your advance on the digital display.

You realize those tractor puller bubba's are light years ahead of us right, I remember in the 80's was the first time I saw compound turbo's and massive fuel, this is at the Young Farmers tractor pull in Wichita Falls Tx. Andy I can't remember the guy's name right now but they live in Big Spring Tx. and are Cotton Farmers pulling with Internationals. Try 5500 RPM and 250 LBS of boost:--) they at one time had two tractors then down sized to one using twins feeding a single and smoke like a dream. BOTW they don't use a thicker gasket to low compression they de-stroke the motor.

Don, yes I bought a 913 pump. Cord also got a 913 pump. I'm not going to put words in Cord's mouth, but I can speak for myself. I felt conned. I too had heard that the pump advanced timing. That's definately something I wanted. You can imagine my surprise when I popped off the DV's and saw that timing is retarded from the idle setting as rack travel increases. That was definately a shocker to me. I was told I would be able to pull higher rpm without the annoying popping of the small pump. I COULDN'T. I was told it wouldn't have the 1200 rpm stumble associated with the 370's. IT DOES. The funny thing is we are both working on setting up our small pumps to put back on. But you don't know that yet. Another 'interesting' tidbit of info was Piers calling me and telling me to not get rid of my small pump because we will use it later. But you didn't know that either

I agree with Chris 100%. I saw a measly gain of 30HP with the new pump and still experienced all of the same flaws that my 175 pump had. The pumps were set up identical. The only exception was my small pump had 191's and the big pump had 181's. Let me remind you that Joe D. has dyno'd both DV's and claims the 191's give absolutely 0 HP. So..... in a nut shell, very large amounts of $$$ for 30HP.



Don,

You speak so highly of the 913's and claim they are SO much better than the smaller pumps, yet all you have ever had is a 913. You haven't had the dissapointing privelage of replacing your small pump to only see a 30 HP gain. How can you honestly promote the 913's as a superior pump when you have absolutely no personal experience with the small pumps. I'll agree, it's a better pump but definately not worth the money. As Chris said, the small pumps will be going back on our trucks soon. Then maybe I can sell my 913 to some one you have convinced.

I was just thinking that maybe this is what that 8100 rpm truck with 200+psi of boost had in Munice. Same shop the pic came from too.



I know it's a little longer then a P7100, but still, has anyone ever done it that anybody knows of? Any reasons it wouldn't work? Cord and Chris S, I'm looking at you guys for the answer, as I concider you 2, 2 of the smartest behind Dr. Joe.



Things that make you go hhhhhhmmmmmmmm,

Andrew

 

[LSMITH]

Andrew, guys like Scheids and Enterprise are getting more fuel than they can use out of the P7100 they have on the truck. Until they start stroking the engine and getting even more insane with the RPM I really do not think there is any gain for the 12 cyl pump, other than cool factor which is definately way up there!!

 

[T. Baker]

Seems like if you really wanted fuel for your quad turbo set up that delivers 250 psi manifold presure you could use any number of big inline pumps. There are big American Bosh pumps on lots of older industial engines and Catapilliar had some really big inline pums too. Would require some machine work to mount and get the gear on the front.

 

[Joseph Donnelly]

The most hp anyone has gotten from the little pumps is around 450 hp, right? The original 913 on Sickly, with torque plate, gov springs, AFC spring (medium spring plus about 15 clicks) got 633 at MM02. That is more than 30 hp difference. If that is all the difference you get, reoptimize the engine for the big pump and find the rest of the hp. I don't know why you Texans can't break 500 hp

 

[TxDieselKid]

Howard,

There are stroked 5. 9B's out there using John Deere pistons. My question was it they are putting that pump on the tractor pullers, what is stopping them from putting them on the Cummins 5. 9.



Joe,

Hummidity!!!



Andrew

 

[Strick-9]

Ouch Joe. That stings.



I'd love to dyno side by side with sickly. I know I can't beat you yet, but I'd like to be judged on the same yardstick just for comparison sakes. I realize that is what may madness is for, but poor planning on my part kept me from having my engine back together in time.



I'll be coming through Vegas in the next few months. Will you meet me at a dynojet somewhere? I'll even pay.



I'm curious to see what it puts out with those vegas correction factors added in.

j fulmer the next time you are in town there is a pulling tractor in a Barn not far from Vernon. It has not been used for a while as It belonged to a friend on mine, grandfather. You would not believe the pump on It.

Maby we can take a look at it. Jim

Strick, you are packin a set of stones man! Can't help but to root for ya!

Sounds good to me, Jim I'm headed to Oregon at the end of the month and trying to get up to Canada (waiting of birth cirtificate so I can get across) when I get back I'll hit you up about doing the timing and we can go check that tractor out on the test drive, I'm a little afraid of going to Piers's shop$$$$$I might go nuts up there!



Strick-9



Chris, are going to use that H2E as a single or are you going to use it with a 35 as twins? That big turbo may lag but when it comes on it don't fool around!



Jim

 

[Strick-9]

LSMITH,



I'm not challenging or talking down to Joe. I just want to be judged on his yardstick and not the local yardsticks because I personally believe there is a big difference. Rather than sit in front of my computer and talk about it, I'd rather go out and see for myself. And I don't want to wait for the next May Madness to roll around.



Jim,

Am I going to use the H2E as a single? I already am. Didn't you see my pulling video? (over 75 feet of lag) Yes, I'm headed down the road to twins. I already had them on, but had a 'small' problem and removed them. We'll just call that a learning experience. hehe. I never intended to run the H2 alone, but I'm stuck with it for now.



When I get a little more time and money, the twins will go back on.

Cord,



If the price is right I will buy the 913/887 from ya? What kinda bucks you talking?



Don~



You guys need to come over if you pass thru Dallas and let me show you what I am trying to get across about these pumps.

Sorry, I didn't think you were. I just respect your energy and relentlessness, takes a pair of stones to push as hard as you do.
