Building A Homemade Flow Bench

It is and has been for decades an invaluable tool to any one interested in increasing the performance of combustion engines.

Building a homemade flow bench.

Open the 5 cfm orifice. I have calibrated this bench using my machine shop s superflow as the standard. Make the port right and the flow is the flow. Generally most diy flow benches modify flow rate by using a manual valving system.

This micro flow bench is the most basic easiest to build flow bench using the flow performance kit fp2 0bs. Flow is not everything. 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. To flow a head you.

Building a motor controller severely increases the complexity of the project but gives more possibilities for convenient automated testing and more importantly consistency. Establishing the numbers step 1. The flow bench hearing is as much a tool as anything and getting the correct port velocity so it can make the turn. Owning a flow bench has become easier cheaper and a lot more versatile with kits that are available from flow performance.

Make sure your bench is sealed so no leakage takes place except through the test piece. Start with a reading on the manometer with the plate completely blocked off for a zero flow depression test. A flowbench or air flow bench is a tool to measure the air flow capabilities of anything that s required to do this. The diy flow bench is a basic system to measure and display volumetric air flow.

Diy flowbench design diy flowbench design and construction what s a flowbench. I regularly have the shop check the flow on one port of a customer s head just to make sure nothing has changed.
