Homemade Flow Bench

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.

Homemade flow bench.

Open the 5 cfm orifice. This micro flow bench is the most basic easiest to build flow bench using the flow performance kit fp2 0bs. A flowbench or air flow bench is a tool to measure the air flow capabilities of anything that s required to do this. Flow benches can teach you a lot but as mentioned they don t show hp.

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. The flow bench provides air flow through a component. Diy flowbench design diy flowbench design and construction what s a flowbench. 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. It is and has been for decades an invaluable tool to any one interested in increasing the performance of combustion engines. Or use a magnehelic as oj mentioned. Make sure your bench is sealed so no leakage takes place except through the test piece.

I m with oj on this one. The diy flow bench is a basic system to measure and display volumetric air flow. 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. Establishing the numbers step 1.

Note that all of the vacuum motors used in construction are recycled so the total cost may vary depending on what one is able to obtain second hand. Home made flow bench worth it.
