Industrial Injection 5.9L Cummins Race Heads

The Industrial Injection 5.9L Cummins Race Heads are designed for the racer / sled puller in mind. Fully CNC ported heads complete ready to bolt on.
Heads are first jet washed in a high pressure spray cabinet to remove oil and dirt, then glass beaded to remove carbon. Next they are checked by magnafluxing, (cast iron only) or pressure testing. They are visually inspected for defects that would make them unusable. Valve guides and seats are removed as needed for porting.
Port development is accomplished using a superflow 600 flow bench with a computer recording all flow measurements.
Many things are considered when designing a cylinder head Port; air flow is only one of the things to think about. Another major concern is port wall thickness.
Anyone can get a head to produce high flow numbers, but if doing so leaves the port wall to thin the casting will crack. High performance Diesel heads are more prone to crack because of the thermal shock experienced by excessive intermittent or long term exhaust temperatures.

The porting is then preformed using a new 5 Axis CNC Cylinder Head Porting Machine with CAD/CAM software specifically designed for cylinder head porting. CNC porting brings unparalleled accuracy to head porting with each port flowing the same. This helps balance the power that each cylinder produces, making tuning easier. 
New High Strength Alloy, Heat Treated iron based valve guides are installed. These guides are heat treated to Rockwell 22 “C” Scale, which produces the ultimate in wear resistance. This is far superior to original guide material, including Bronze. The guide incorporates a spiral grove inside the guide to hold oil and aid the lubrication of the valve during engine operation. 
Guides are then honed (not reamed) to exact size using a diamond honing mandrel. Diamond abrasives allow for consistency of size, surface finish, and bore geometry with no variation from guide to guide. The guide size is then verified using a valve guide bore gauge. 
As needed the head receives new Premium valve seat inserts made from a true Nickel Based Non-Magnetic material that was developed for extreme operating conditions. 
Next the head is treated to a multi angle valve job to help maximize the flow of air in and out of the head. This is accomplished using a Serdi 100 guide and seat machine. Serdi uses a solid carbide straight shank pilot. When inserted into the valve guide, it simulates the real valve stem during the centering process. This guarantees the valve seat is finished for a perfect valve to seat match. 
Using CBN or Diamond tooling the head is given a new surface. With our berco milling machine we can control the surface finish to accommodate different head gasket types. For example MLS head gaskets require a very smooth surface finish.
Finally the head is jet washed dried and assembled with new valve seals and new performance valve springs.

Bad Cummins Connecting Tubes

The Importance of Genuine OEM Injector Connecting Tubes

Most people like to save money when and where they can. In this instance, people have been liking the idea of saving money when it comes to buying new injector connecting tubes. Why spend $50 - $75 on genuine OEM connecting tubes when you can spend $10 - $30 on some knock off brands that claim to be genuine? After all, it is just a tube. Right? Unfortunately the dismal truth to that question is; wrong. Cummin's folks in every direction are getting cheating into buying these aftermarket connecting tubes in the name of saving money, but in return, on a rampant level, end up spending thousands more dollars in repairs caused by contamination. 
The problem we have found with these aftermarket connecting tubes is metal shavings and/or flakes are being left over from the boring process. The only way to see these tiny flakes is through a bore scope. (See bore scope images below.) These tiny pieces of metal are finding their way through the connecting tubes and into the injector, scratching, damaging and clogging the injector and nozzle.

How To Check For Bad Connecting Tubes
The bottom line is; buy genuine OEM injector connecting tubes. It is worth the extra money. We have had so many problems and implications of customers expecting us to honor a warranty on an injector(s) that have failed, only to find out it wasn't a faulty injector, it was contamination from an aftermarket connecting tube that caused the problem. Because of the common occurrence of these issues; Industrial Injection will not be honoring defective aftermarket connecting tube related injector failures. 
Industrial Injections acknowledges that some aftermarket parts are good in value, but that some aftermarket parts only lead to unnecessary problems that could have been avoided by buying a proven OE or known good product.

ATS Diesel 5.9L Cummins Aurora Turbo Kits

Aurora 3000 Turbo System - 2003 + Dodge Ram 5.9L Cummins 

The Aurora 3000 is a quick spooling turbo charger that is great for all around performance on your 03+ Dodge 5.9L Cummins. The 58mm inducer on the turbo is a very nimble and highly responsive unit. Safe for stock engines and stock components, towing and daily driving become much easier due to the turbo doing more work, instead of relying on the engine with a restrictive factory turbo. The increase air volume will utilize all fuel injected into the cylinder creating a more complete and efficient combustion event. This will result in lower EGTs, better throttle response, and a more efficient/useable torque curve.
