All of our products are tools to remedy an issue with the diesel engine. This head is no different. It greatly improves airflow for a diesel engine. To do this, larger ports were needed. This slightly reduces performance below 2,500 rpm. If lower compression or large cams are used with this head, this low rpm performance is degraded further. Are you running a 62mm turbo? Don't waste your money on our head. You do not have enough flow potential to take advantage of the better ports. That being said, if you are serious about building big horsepower, this head is a must!

What does it flow? Since motorsports are fueled by testosterone and egos, any claims about flow are highly contested by people that think their stock head outperforms our head. For this reason we don't post flow numbers.

How much more power can we expect to see? Since motorsports are fueled by testosterone and egos, any claims about horsepower are highly contested by people that think their stock head outperforms our head. For this reason we don't post dyno numbers. At Hamilton Cams we use dyno and flow numbers internally for research, but not for marketing. We race trucks, not flow benches or dynos.
