Product Description:

This replacement Cummins cam is the most efficient cam we have tested for moderate street trucks. It will net you the best economy of all of our cams. Due to its short duration and wide lobe separation angle, it also has the least overlap(when intake and exhaust valves are open at the same time) of any of our cams to kill in-cylinder EGR on engines that have higher drive pressure than boost pressure. This is usually found with stock turbos that have a very restrictive turbine housing or turbine wheel. On a truck with a 62mm turbo and 80hp injectors, this cam picked up 40hp at 1700rpm due to the fact that it moves so much air at lower RPMs and helps the turbo spool much sooner. If you live at high altitudes, tow heavy or are looking for the best efficiency possible for highway driving, this cam will help you considerably. The 178/208 cam makes an engine with a larger single turbo easier to drive on the street and makes part throttle operation better throughout the entire rpm band. Install with the intake from a 97-99 centerline.

Although it works great as an efficiency cam, it is also starting to be popular with common rail engines that have larger single turbos or that have larger valves and ports. Larger turbos typically have less low rpm response as do cylinder heads with large ports and/or large valves. In these applications, it will really help get large turbos spooled much earlier.
