Cylinder Head Porting Cummins 24 valve

by admin on January 9, 2010

Cylinder head porting on a diesel engine refers to the process of modifying the intake and exhaust ports to increase the amount of air going into the cylinder. Porting the heads provides the finely detailed attention required to bring the engine to the highest level of efficiency. It has been said that an internal combustion engine is nothing more than an air pump, and the more air it can pump, the more power it will make. Most often the guy who pays his bill without questioning it is the one who has already tried porting and has an idea of the work involved. Success at head porting does not happen overnight. It takes skill and practice. We offer over 30 years of head porting and air flow experience. We are asked all the time, does it help to port diesel heads when you can increase the boost? The answer is ABSOLUTELY. When you increase the boost, you put more air in the cylinder. When porting is done right, it will also put more air in the cylinder. Together you maximize the air flow and the horse power.

I personally run Industrial’s full race head on my 2007 Dodge Cummins and I have mated that cylinder head with Industrial’s Injectors and Race Compounds.

The question I get the most working in this industry is “Will this part or that part give me more boost?”

This is the most ridiculous question, the hardest thing to explain to people is that the boost number you see on that gauge in your cab is simply a measurement of restriction.

If you have a stock turbo and it operates on a stock engine at 35 pounds of boost and you are making 325 horse power to the rear wheels and that turbo is moving 61 pounds of air per minute. Imagine how much power you could make with the same turbo moving 61 pounds per minute at 15 pounds of boost/resistance!

That is what these ported and polished cylinder heads will do for your truck.

I have installed the Industrial Injections Race Compounds on many trucks over the years. Those turbo chargers on a stock engine with basic bolt on’s and fuel upgrades will push 80 PSI of boost no problem. Those trucks are capable of 800-1000 horse power dependent on tuning.

With their race head on my personal truck with the same turbo chargers I see only 40 PSI on the gauge in my cab but I am still moving the same pounds per minute of air. To be able to run an 800+ horse power truck on the street with very little to no smoke is what really makes these cylinder heads worth their weight in gold.

If you are looking at purchasing one of these cylinder heads but you are having a hard time justifying the money, I hope this little review helps you make a wise decision. They are worth the money and not having to worry about EGT’s and high drive pressures is so nice when you want to do a lengthy wide open throttle run on the freeway!
