Building A Homemade Flow Bench

I regularly have the shop check the flow on one port of a customer s head just to make sure nothing has changed.

Building a homemade flow bench. Establishing the numbers step 1. Make the port right and the flow is the flow. Owning a flow bench has become easier cheaper and a lot more versatile with kits that are available from flow performance. The diy flow bench is a basic system to measure and display volumetric air flow.

This is a valid option but we instead opted to build a motor controller. A flowbench or air flow bench is a tool to measure the air flow capabilities of anything that s required to do this. Diy flowbench design diy flowbench design and construction what s a flowbench. 2007 sbn a drag week winner first only sbn a car in the 9 s till 2012.

Start with a reading on the manometer with the plate completely blocked off for a zero flow depression test. 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. This micro flow bench is the most basic easiest to build flow bench using the flow performance kit fp2 0bs. Open the 5 cfm orifice.

Building a motor controller severely increases the complexity of the project but gives more possibilities for convenient automated testing and more importantly consistency. Make sure your bench is sealed so no leakage takes place except through the test piece. I have calibrated this bench using my machine shop s superflow as the standard. The flow bench hearing is as much a tool as anything and getting the correct port velocity so it can make the turn.

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. Generally most diy flow benches modify flow rate by using a manual valving system.
