Homemade Flow Bench

Flow benches can teach you a lot but as mentioned they don t show hp.

Homemade flow bench. Diy flowbench design diy flowbench design and construction what s a flowbench. I m with oj on this one. Home made flow bench worth it. 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. 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. A flowbench or air flow bench is a tool to measure the air flow capabilities of anything that s required to do this.

With high tech electronic sensors and a patented state of the art air flow metering element effective flow rate measurements can now be made with nothing more than an average shop vac for an air source. This flow bench will use blower motors scavenged from household vacuum cleaners to generate the airflow necessary for testing. Make sure your bench is sealed so no leakage takes place except through the test piece. We had a nice superflow bench at epa and while it was cool and all it really is just a big shop vac and an incline manometer which you can make easily.

It is and has been for decades an invaluable tool to any one interested in increasing the performance of combustion engines. 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. While using a shop vacuum to move air through the flow bench the fp1 processor estimates the flow data to 28 wc test pressure in real time as the flow test is being performed. Typically the pressure drop across the component is held constant 28 inches of water or about 1 psi is a common standard pressure for cylinder heads and the air flow is measured.

This flow bench uses a shop vacuum for estimated flow data. Or use a magnehelic as oj mentioned.
