Building A Homemade Flow Bench

This micro flow bench is the most basic easiest to build flow bench using the flow performance kit fp2 0bs.

Building a homemade flow bench.

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. 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.

Diy flowbench design diy flowbench design and construction what s a flowbench. 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. Building a motor controller severely increases the complexity of the project but gives more possibilities for convenient automated testing and more importantly consistency. Open the 5 cfm orifice.

A flowbench or air flow bench is a tool to measure the air flow capabilities of anything that s required to do this. The flow bench hearing is as much a tool as anything and getting the correct port velocity so it can make the turn. Establishing the numbers step 1. I regularly have the shop check the flow on one port of a customer s head just to make sure nothing has changed.

It is and has been for decades an invaluable tool to any one interested in increasing the performance of combustion engines. Flow is not everything. This is a valid option but we instead opted to build a motor controller. I have calibrated this bench using my machine shop s superflow as the standard.

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