Record Breaking Horsepower:

Unmatched Port Flow Combined with World Class Quality Control

When MBE began guaranteeing the flow numbers of every cylinder head sold, it caused quite a stir among our competitors. After all, MBE’s cylinder head designs already produced the highest flow numbers—and the most power—in the industry, but now every head was guaranteed to match that number or your money back. We found it interesting that about the same time other cylinder head specialists began telling their customers that flow numbers aren’t important, but that just isn’t true.

Owner Matt Bieneman learned first-hand just how important quality flow can be in terms of producing power while working on Joe Gibbs Racing’s NASCAR Sprint Cup Series engine program between 1999 and 2001 as the Cylinder Head Department Manager. Bieneman saw then that every cfm of flow gained in a properly designed port was equal to one horsepower on the dyno. Discoveries in the porting room lead directly to better performance and checkered flags.

At MBE we’ve been successfully producing the highest performing cylinder heads in all forms of racing for years. We know that the proper cross-sectional areas combined with the right port velocity with maximum airflow in order to pack the combustion chambers with more air and fuel than any other cylinder head option out there. This can only be done by understanding the flow coefficient as well as the flow curve at every point in the valve’s movement. And doing that has also helped us develop a unique understanding of how to tailor the power curve specifically to each application. The needs of a drag racer, a circle track racer and a big-inch truck puller are all unique, and at MBE we can give each a cylinder head package custom designed to exceed expectations in that particular arena.

When designing a port, we precisely control the cross-sectional area of the flow path beginning with the point that the air exits the carburetor or throttle body and follow that through until it exits the exhaust port. This ultra-precise level of control allows us to identify and remove choke points from the troublesome areas that other port designers have simply accepted as “good enough.” Our improved designs create ports that are unmatched in the industry in terms of both pure flow numbers and the power they are capable of producing.

In addition to the unmatched production from our cylinder head and intake manifold designs, MBE has also invested heavily in both time and machinery so that our precision and quality control are second-to-none. This is the reason we are the only major cylinder head and induction specialist in the industry that is able to guarantee the flow numbers on every cylinder head we offer. Our port flow guarantee is no marketing gimmick; we believe it is key for you to be confident that you will receive the same quality components that we provide our biggest name racers and engine builders. If the competition isn’t willing to put the same guarantee on its products, what does that say about their quality control?

Producing great cylinder heads and manifolds is both an art and a science, but we believe that quality is always measurable. That’s why we always provide flow numbers for every cylinder head we make. At MBE we know we have the best cylinder heads in the business, and we aren’t afraid to prove it.
