PERFORMANCE HEAD PORTING

DC Cycle and Racing takes head porting and

design seriously. We design and test cylinder

heads with our Super Flow (flow bench) on a

regular basis, including EVERY performance head

that leaves the shop. Using Port Flow analyzing

software, we map out specific areas in the ports

using pitot tubes. These tubes tell us the velocity

in the ports, as well as areas of slow moving air.

We also use flow strings (wands) and flow balls to

see what the air is doing inside the ports. The

valuable information these tools provide allows

us to modify your heads for the best flow and

velocity for your application -- whether that is track

or open road.

.

In addition to testing the ports, we finish all of the head packages with custom intake valve seat angles, and full radius-ed exhausts seats. We use the race-proven Rottler SG7 seat and guide machining to accomplish this. Our heads are not only tested on the flow bench, but we also put in countless hours of testing and working with our in-house dyno, and even more hours on the track and open road testing our work. We sponsor a variety of local and national riders and race teams to give us feedback on our work, and we can confidently say we make some of the best performing heads on the market.
