i know for sure it is avalable on the EUI/ecm controled versions.. there was one at school that had the jake brake on it... it is avalable as an add on item

 

cummins engine brake was/is available, it's called c-brake. all our N14s have it.

 

Anybody out there know what a shining 290 is??,now that was an engine.Could do an in-frame for the cost of a pump for a cat.or buy a rebuilt pump for 300. Those were the days,when cummins was known as the poor-mans diesel.

 

Are you talking about the Formula 290?

 

What, you guys don't like the 8-V71 Detroit? Used to drive a '74 International dump truck with one in it. By the end of the day, your ears would ring and if anyone said anything to me, I'd have to scream "WHAT DID YOU SAY?".
On the other hand, I also got an oportunity to drive an '83 Chevy Bison (one of the last years chevy made a semi truck) that had a twin turbo 400 or 450 HP 8-V92 in it. That thing rocked! Power from off idle to screamin wide open. The boss had it out in a muddy field, and slipped the clutch trying to get it unstuck (rookie).
It'd pull 100,000Lbs gross weight (tanker full of water... I know, overweight) like it was pulling an empty trailer.

I've also driven Cat power (not all that powerful) and Cummins. I like the Cummins much better.

 

My dad drives truck and he prefers the cummins cause he claims the cats rev up and down really slow, is there any truth to that?

 

Everything I've driven w/ Cats in them were dogs. Cat engine parts are way more expensive, too!

 

I also prefer the exhaust note of the cummins better. Its seems much louder and the jake on a cummins is REALLY loud! I have also heard that CATs are basicly their tractor engines with different cams and such.

 

my Big cam 400 would walk away from my 8v92ta silver 450 in the hills, on the flats the 8v would pull away and the jakes are 2x as strong on a cummins

 

My dads m11 has somethin wrong with the jake on it. Its really weak. You might as well not even use it. It cant even hold the truck back on a 6% grade while its EMPTY!!! But he plans on takin it to the shop and replacing the jake.

 

Has he tried adjusting the jakes? They have to be adjusted just like the overhead.

 

Yes they have been adjusted.

 

could be due to fueling of the engine, or just by weight of the rotating mass... if you have a heavy double disc pot flywheel and heavy transmission, the engines all will be slow[er] at going up and down the rpm band with no load...

and if you want to hear something different, if you get a chance to play with a new isx in service mode, cut out 5 cylinders and have it idle on 1 cylinder... sounds like an old lister...

 

I run a T-800 KW w/ a 430 hp C-12 Cat. It is a tad slow at low boost, but once it comes on, you can fuel come on hard. It has a 'gated turbo, so it spools pretty darn quick. Particularly when empty. It accelerates faster than Mack Vision w/ a E-7 427.

 

Yes ive heard the CATs dont start to add much fuel until like 8lbs of boost which is what probably causes the slow reving.
