Flow Testing

One of the newer additions to the cylinder head machine shop is a new Superflow SF-600 flowbench. 

This larger unit replaces our previous bench, a Superflow SF-110 that was one of the first commercially available flowbenches in the Madison area.

The best-known use of a flowbench is to measure the flow of air through the intake and exhaust ports of a motor.  This is an indicator of the efficiency of the port configuration.

With the incredibly high horsepower to displacement ratios of today’s  sportbike motors and the competitiveness of  the twins classes, the ability to assess the cylinder head performance is critical.  You can tell if you are doing a good thing to a cylinder head with your porting tools or a bad thing (sometimes the only way to discover the good things is to do a few bad things…..spoken from experience).

Another use is the flowtesting of carburetors, throttle bodies and exhaust manifolds.

In engine development this allows a tuner to balance the systems and choose the various external components.  For example, if a cylinder head will flow 175 cfm (cubic feet of air per minute) at the maximum valve lift the cam to be used provides, there is no reason to fit a carburetor that flows 190 cfm, unless a reduction in throttle response is desired.

This SF-600 flowbench is the same used by the leading cylinder head specialists throughout the country, and even the world.  It is available for cylinder head development

Flowtesting is done by the hour or day.
