Engine/Transmission (1994 - 1998) Highest HP 12V & 24V's

[9 Lives]

I think this has been posted some time ago. I wanted to re-issue this question possible with updates.



Who in the US has the highest lets say top 5 cummins engines wether its 12 or 24. I know local down the road from me by the name of Tim Helms has a 12V just over 1,055HP and 2K+tq. im sure most of these trucks will be owned by garmon,haisley & shied?

1000 on an engine dyno and 1000 on a chassis dyno are two different world's.



Both with #2 only

Im talkin RWHP

 

[Jim Fulmer]

You should post a dyno sheet or a video then so we all can see what a grand on #2 looks like! I personally have always wanted to see it..... actually feel it.

go down to the video & pictures section. And its the I think 4th video from last on the page.



Don't know him personally. How much HP are Shied, Haisley and them putting out on their trucks?

 

[Jim Fulmer]

Read my first post... ... #2 only!



Scheid, Hasiley, EEP ect... ... ... allot more than that!

From my first post... im just trying to find a list of maybe top 5 if not top 10 of the highest HP Cummins engines in the united states... . drugs or not. Im just curious of how much HP they are can make out of these engines. And who is #1 in the country

It serves no point to tell everyone what we make because no one believes it.

 

[9 Lives]

So there has been no world records set just yet? I was just curious



2000 RWHP can it be done?

 

[Jim Fulmer]

Hey Chris! Well I for one can believe it! Maybe it's because I have made say 100 hard passes on the road at 700 hp or better and it in no way looks, sounds or feels the same.



The first truck I ever heard come hard out of the hole was Scheid at Muncie 03', I was at 650 hp then and just couldn't believe the difference.

I just dont want to get in the middle of a peeing contest, it seems these threads eventually go that way. But since I allready opened my big mouth, I can definately say that 2k is obtainable, just not so comfortably. We aren't quite there yet, but the light at the end of the tunnel is getting close. Right now our biggest limiting factor is the head, rods, and the block. but were working on something to remedy those problems. I need a major sponsor to be able to get what I need, so for now it's kind of on the back burner.

 

[Jim Fulmer]

I'll piggy back on a few things here:



My guess is guys are splitting blocks... . ok!



The head sucks, sorry but it does. It is designed to cool not flow. When I went back through my head last year we were playing heck getting it to flow much more than the low 200's, it really needs to flow about 400 cfm.



Rods could be some billet stuff to stand the extreme cyl pressures.



I'm in a smaller boat than Chris as I have an even more limited budget as it takes me months to pull off a change. The current one is minor, more cleaning up and it's still taking a few months. It's not worth it to me to have a big Visa bill for 6 months.

Chris,



Our you having block failure due to the rpm range you are trying to run or because extreme cylinder pressure/boost? I'm sure a nice little(or big) billet block would eliminate that pesky block busting problem. On the 12 valve forum your not likely to get a ton of skeptics screaming about how your "heavy; overfueled" motor is not making what you claim... different story on the Competition forum. With an awsome billet cylinder head, rods, and block I don't think it stops at 2K.



Good luck with the truck this year,

Jonathan

Jim we posted on the same thread at the same time... you beat me though. We are up too early!

4:30-5:00 is my normal time..... muster is at 0700.

9 lives - Tim has a great running motor, he made 1020 on the bottle and a very solid 832 on #2. Jeff Garmon made the 1055 with the bottle. Darren made 857 on #2 and Jim Fulmer is around the same on #2.



Those are the biggest CHASSIS dyno #'s I've seen or know of for each flavor.



IMO, Engine dyno #'s from the Scheid shop are really up there. I don't know the latest numbers, but I do know 1500 has been reached (and that would be old news I'm sure to the owners of the trucks).



The difference is more that just the loss of the drivetrain. Sledpulling engines are tested the same way they are used. Big RPM, and pulled down to around 3k, just like on the track. Using this method to measure will provide more HP if for nothing else you are using the "stored" energy in the rotating assembly to help make HP, where in a run when you are accelerating that same rotating assy. is actually costing you HP. (difference of accelerating a mass and deccelerating a mass)



I just wish someone would post an engine dyno sheet for some of these big pulling motors then those that don't believe can.



And yes, I can tell you once you get to 800 chassis HP and put it on the track, you will start having issues with blocks and rods.

David thanks for the post.

One thing for sure when you get to mega HP levels it's difficult to measure it reliably and consistently because of the limitation of tires, drivetrain and dyno equipment. Then to complicate matters more those high HP rigs have limited driveability and are more difficult to spool and bring into their optimal power band than rigs running more streetable power. When things come together though you can throw down some impressive numbers.

Not to brag but you would be amazed at how well it drives at 800 hp, step down to a 370 size injector and it's perfect in everyway no matter the speed, cruise on/off doesn't matter.

Jim- I think your tellin a tall tale. Bring it up here to the land of cheese and let me try it out for a month or so and I will let you know.
