What is flow bench used for?
An air flow bench is a device used for testing the internal aerodynamic qualities of an engine component and is related to the more familiar wind tunnel. It is used primarily for testing the intake and exhaust ports of cylinder heads of internal combustion engines.
How much does a flow bench cost?
for Price Details The Standard EZ Flow System kit sells for $999.
How can I make my head flow better?
The first is to back-cut the valves. Most valves have a wide, 45-degree-face angle. By narrowing that angle with an appropriate back-cut, you increase low-lift flow because there is less material for the air to flow around and there is a smoother transition on the backside of the valve.
How much does it cost to flow test a cylinder head?
Flow testing: $75 Flow testing of one intake and exhaust- performed on our custom built bench at 28″ of depression with flow sheet provided. Valve Profiling: $50 Produces dramatic increases in low lift flow. This creates additional horsepower and torque.
What are good flow numbers for heads?
Most cylinder head experts will tell you that a number above 70 to 75 percent is considered good, especially if the intake port flow is also a good number. While the temptation is great to concentrate on the peak lift flow numbers, we suggest concentrating on the mid-lift flow numbers and how they compare.
What was the first flow bench?
The first flow bench was, in fact, my mother’s vacuum cleaner. I mounted the head to be tested (an A-Series head as per the Austin/Morris Mini engine) on a bare A-Series block. The head was equipped with a way to precisely open the valves.
What are the shelf standards and brackets for the flow bench?
Shelf standards and brackets can be used to mount the flow bench parts. These double locking units from KV are highly recommended. The standards are 36″, and the brackets for the bench are 14.5″ long.
Is there a bench that can be used for flow heads?
My friend Roger “Dr. Air” Helgesen built a bench that worked along the same lines as this in the early 1980s and still uses it today to flow heads and intake manifolds.
What is a floating pressure-drop bench?
At this point we have, with a floating pressure-drop bench, a flow testing situation that more closely mimics the pressure differentials seen in the cylinder/intake port of a running engine. So what are the advantages?
