Building A Homemade Flow Bench

I have calibrated this bench using my machine shop s superflow as the standard.

Building a homemade flow bench.

Make the port right and the flow is the flow. Make sure your bench is sealed so no leakage takes place except through the test piece. The flow bench is used as a tool for measuring and quantifying modifications and improvements made to items such as automotive cylinder heads and carburettors by detecting air flow improvements. Open the 5 cfm orifice.

The diy flow bench is a basic system to measure and display volumetric air flow. Start with a reading on the manometer with the plate completely blocked off for a zero flow depression test. Owning a flow bench has become easier cheaper and a lot more versatile with kits that are available from flow performance. Establishing the numbers step 1.

I have a head flowed by them then put the head on my bench and adjust factors in the calculating tables to get the same readings. Flow is not everything. A flowbench or air flow bench is a tool to measure the air flow capabilities of anything that s required to do this. This is a valid option but we instead opted to build a motor controller.

Diy flowbench design diy flowbench design and construction what s a flowbench. Generally most diy flow benches modify flow rate by using a manual valving system. Building a motor controller severely increases the complexity of the project but gives more possibilities for convenient automated testing and more importantly consistency. The flow bench hearing is as much a tool as anything and getting the correct port velocity so it can make the turn.

I regularly have the shop check the flow on one port of a customer s head just to make sure nothing has changed. This micro flow bench is the most basic easiest to build flow bench using the flow performance kit fp2 0bs.
