About Race Flow Development

Race Flow Development specializes in getting the most out of your engine for Road Race, Circle track and Drag Racing applications. RFD is a full service machine shop and uses only the best equipment. We have a full 5-Axis Simultaneous CnC machine with Centroid control. Rottler Seat & Guide machine, Berco surfacer, Saenz & custom flowbenches.

Our Saenz 600 is used for flow and high air speed testing. It can flow 620 cfm @ 28″ and is also used to drive the wet flow tests. It’s primary function is velocity testing and with a booster box can reach very high air speeds. Our bench has been calibrated with sharp edge orifice plates to the American Society of Mechanical Engineers MFC-3M-1989 national standard. No inflated flow numbers here!

Great cylinder heads and port design is a never ending process. The hundreds of hours designing, hand grinding, digitizing and flow testing ends up on the dyno and race track, only to start the process all over. RFD never rests on it’s latest development but continues to develop on an on going bases. It’s the research and development that drives RFD and it’s what we do best. All of our CnC ported heads are custom built one set at a time assuring you the best cylinder head for your application.

We give our in-house 5 axis CnC a real work out on a daily basis. All our digitizing and programing is done in-house to allow us to make the best use of CnC, CAD modeling as well as CFD modeling. All of our programs can be modified to fit your application and that’s just what we do. Every CnC project is adjusted to fit the application. Not shelf stock run-of-the-mill CnC programs, RFD performans all custom work. We can make very accurate adjustments in cross sectional area & port volume to fit any application.

Custom CnC projects and CnC programing is our specialty. If you have a Head you need duplicated “private label” CnC is just what we do. We are THE most trustworthy CnC shop there is, we will not share you sensitive data and will do everything in out power to make sure your project is a success.

Our current area of development specialization involves SB2.2, 10 & 18 degree heads for circle track & drag, NHRA Pro Stock, V8 Drag Racing & Road Racing and as always large CI big block.
