Cummins N14 650-700hp build

International Harvester was using water with fuel (Kerosene) 100 yrs ago at the turn of the 20th Century. Not really a new thing.
Water / Kerosene = Mothballs / Gasoline

 

I know that you do. Was informing op.

 

Everyone has bad engines. Ive seen it in every brand. Sucks but it happens. 1997 detroit wrist pins. 3406c wrist pins, 1994 3406e that they failed to wash all of the sand out from casting the blocks, that sucked, some N14 fretting, some did not, some eairly in life some later. Everyone has lemons. 1999 Internationals with n14, International started factory filling with extened life coolant, however they never ran this by cummins. Thus leading to major warranty for coolant leaks at every gasket. Once performed first service on a 2001 3406e, dropped oil to find a washer with cat stamped in it. Warranty paid for complete disassemble to find were the washer came from. When all torn down, concluded it was a extra that someone dropped in engine on assemble line. Then was put back together.

 

Btw if you over haul a N14 you should line bore the block. No bearing problem after that.

 

Like equipment today, some didn't really understand the function. The Kerosene tractors were usually hard to start do to not giving enough time to allow the carb refilled with gas, after running on Kerosene. International made a flywheel engine that started on gasoline, and after it warmed up you converted it over to kerosene, and start adding water with the kerosene since water basically raises the btu of kerosene. Our forefathers were very intelligent!
The distillate tractors you speak of are easy to spot, many still have the small gasoline tank on them.

 

It's not about bad engines, the long rod does not work well with high torque, plain and simple, lug them and they will fret quicker than if driven like an old big cam.

 

Ive always driven a cummins 150 or so RPM's higher then a cat. Detroit even higher and even higher for a two stroke.

 

I agree, I feel its true for all engines. Lug them down and its hard on them. Rpm doesnt hurt them. I run my 12.7 detroit at 1500-1600 rpm going down the road. Even detroit says 1300 is ok. My fuel milage is better, egts are lower, and can keep boost psi lower. Now that is with aftermarket turbo. I only use 13th gear empty, and or over 70mph. I know cats have the best torque at low rpm, but I still dont think its a good idea to lug it that low.
