Building A Homemade Flow Bench

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

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. Owning a flow bench has become easier cheaper and a lot more versatile with kits that are available from flow performance. 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.

It is and has been for decades an invaluable tool to any one interested in increasing the performance of combustion engines. This is a valid option but we instead opted to build a motor controller. Flow is not everything. 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.

The flow bench hearing is as much a tool as anything and getting the correct port velocity so it can make the turn. Open the 5 cfm orifice. 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.

The diy flow bench is a basic system to measure and display volumetric air flow. A flowbench or air flow bench is a tool to measure the air flow capabilities of anything that s required to do this. Establishing the numbers step 1. Building a motor controller severely increases the complexity of the project but gives more possibilities for convenient automated testing and more importantly consistency.

2007 sbn a drag week winner first only sbn a car in the 9 s till 2012. I have calibrated this bench using my machine shop s superflow as the standard.
