This is only the second Flowbench I have built. The first one was modeled after a commercial one but was under powered. I could barely get 8" w.c. test pressure on intake testing.

I have been working on this thing for quite some time now. This second design is not of the Laminar Flow type benches like Jerry Branch or Don Tilley use. This design is more like the larger comercial Flowbenches most commonly used by alot of cylinder head porter's nowdays.

This new bench was made by using some old plans from a old car magazine from the early 90's.

My compadre, Tone from Green Bay, Wisconsin, knowing that I like Science Project's, turned me onto this stuff. I owe all my inspiration for this madness to Dr. George Fishbach!! Besides it's winter and what the fuck else is there to do when it's too cold to ride.

This new bench will have the potential of as much as 1600 CFM @ 28" w.c. I'm starting out with a 400 CFM @ 28" w.c. capability. This is mainly because due to the cost of the vacuum motors. You really only need 300 to 600 CFM to do cylinder heads. 1200 to 1600 CFM comes into play when you're performing serious intake/carb/EFI throttle body testing.

Another reason I'm building this is I can't afford a commercial one which can cost thousands of Dead Presidents. In building one myself, the dough I save will allow me to hook up a cool computer and add on stuff for the bench from Audie Technology www.audietech.com. They sell high- tech, time-saving computer gizmo's for flow benches.

The Flowbench with 400 CFM capacity can be built for under $500.00 US. The Flowbench cabinet is made in two section's top and bottom. It's dimensions are 27 x 38 x 40 inches for the bottom cabinet. The top part with the lighting and where the manometers are located is 18 x 38 x 40 inches. I designed it in two sections for portablity and ease of construction. The 3/4-inch particle board is way heavy.

The cabinet was built using a Skil saw, Roto Zip drywall tool, Black and Decker workmate, battery powered drill and various wood working hand tools. You also need to have access to a lathe and milling machine. They are useful for manufacturing the metal parts that will be used inside the bench.

These initial photos and text were kinda of a update progress report showing where I'm at with all of this. So far this winter the Flowbench project is moving along nicely, mainly because of a lack of any kind of a fucking "Dead Line". When you have a deadline on a project, no matter what it is, you are doin you wind hurrying some aspect of the thought/building process. Which means it can turn into a "Cluster Fuck"!

So let Bikernet know what you think of all this. Does Pablo have no life and too much time on his hand's?
