Flow bench?
 

Im curious if anyone has built their own flow bench to test various parts for their car. Im starting to look into building one, so any advice on where to aquire plans, tips, etc. would be greatly appreciated.
Thanks :)

Paul Yaw built his own flowbench. I can't remember how much info is on his website, but as I recall there's a fair amount there if you look around. www.yawpower.com
