Another newbie says hello (and help) - Intro and bench description

[115-1170124124]

[color=#000000]Hi all, This is my first post, after reading as many others as I could. A friend of mine loaned me his AudieTech Flow Quik setup, but wants it back ( a lot of nerve!) so I decided to build my own. Not having his $$ has led me to a pitot style bench and, initially, a manometer setup. My needs are somewhat less than most on the forum as I am interested in 100cc engines in motorcycles. (If I get really crazy, I may go all the way to 175cc!) My shop vac has shown a corrected 60CFM @ 28 in wc (and over 40CFM @ in wc actual using the FlowQuik setup) on a set of heads that is cleaned up, but not really ported, so you get the idea. Just before I found the forum, I started construction of my own bench: A used computer table from the local thrift store supplies the structure ($3) and I fabricated a 10 in (inside) cube to provide the plenum chamber. One of my cylinders is used as a head adapter so I get the real effect of shrouding. I used some

Hi again, I tried to post a pic of the bench, but it didn't work so you can see it here (along with the reasons I want it!).

Hello there Doug, welcome to the Forum.

That all sounds like a pretty good effort and should work very well. I cannot help verify your pitot calculations, but others here far more knowledgeable in that area will be better able to help.
