12 valve cummins how many miles

The free mods begin with the AFC air fuel control housing shown below, which sits at the rear top of the aforementioned P injection pump. In fact, performing all of the above often results in a hp gain, if not more.

One common injector comes from the hp version of the valve used in marine applications. Made by Bosch, the marine injectors feature a 5-hole nozzle with 0.

The largest streetable injector we come across are the popular 5x0. Even though it was designed to see 20 psi of boost in the 5. While making 35 to 40 psi courtesy of a disabled wastegate , the HX35 not only yields more power, but lower exhaust gas temperature EGT as well.

And with a larger 14cm or modified ported factory 12cm exhaust housing, exhaust flow increases, drive pressure drops and the HX35 can support rwhp — not bad considering these engines start out with to hp at the crank, depending on the model. But while a worked over factory valve head can flow extremely well, due to the way they were cast, there is only so much material you can remove before you compromise the structural integrity of the head they often crack after limited use.

Looking to get more flow and reliability out of a competition valve head, Hamilton Cams had completely new cylinder heads cast pictured above , designed specifically to incorporate more meat around the ports especially on the exhaust side. More material means more porting material removed is possible without sacrificing durability cracking.

The truck was a competitive sled puller, ran 9s in the quarter-mile yes, 9s! At the dragstrip, nitrous is added to the equation, which culminates in 1,rwhp and 9-second blasts through the Check out this 9. Sign up for more restomod content to add horsepower to your inbox.

So yes they are that good. Originally Posted by jimcumminsw. I want to see the "Real Marines". The Cummins 5. I ordered it in late 06 so that it would have the 5. NEVER be the beta tester for new engine Love my 'Tractor Motor' And like the Ford, expect the truck will start having issues long before the engine filter and oil changes mandatory of course.

Safe travels. My Ram with the Cummins is still on the road towing. I just left my trailer in Oklahoma and drove to Minnesota for Thanksgiving and the odometer hit , on the way. It still does not use any oil and gave me about 20 mpg running 75 mph. These engines are good for , miles before thinking of rebuilding under normal circumstances. Hey you 5. Particularly interested in governed peak RPM.

Oh I know I could just hold the peddle to the floor and read the tack, but is that what the Dr. I have a 5. It pushes a motor home and tow that weight approximately 27, lbs. I change the oil every 6, miles and have yet to add any oil before the change.

I plan to keep it another , miles. By then I'll be 90 years old and will have gotten my moneys worth. Originally Posted by SMB. New transmission, transfer case, torque converter, swash plate, front end suspension bushings, three new radiators, front and rear main seals on the engine. Also having a BD exhaust brake installed. Truck still runs great with no obvious issues. But like always, when we started to dig in we found all these other things that were on their last legs.

The output shaft of the transmission has a drain hole where it couples with the transfer case. This drain was blocked with sand and other grit.

This cause a hole to rot right through the transfercase. And one of the bolts that holds the t case to the transmission rotted right out of the case.

The radiators all had seen better days. But most was my fault as I had never serviced them in K miles. Front suspension bushings was just an inexpensive fix as the factory were hard and distorted.
