Flow Bench
« on: May 16, 2011, 12:16:22 pm »
I was at a friends house over the weekend and he was showing me his brand new flow bench. What exactly does the flow bench do for you and how does it make you go faster. Ok go.

What model bench flow was it?  Like Sam says, kind of strange he had the time to show it to you but not tell you what good is it for. 

On the other hand, didnt Mike just bought one ;)

Sorry but I wanted some additional info, yes Mike explained a little about what it does , but I want to know more of how it works. I understand that it measures flow, but what do you get from that. Obviously none of you guys know anything about it, so I will just wait for Mike to fill me in further :)

Well....kinda like the more you flow
the faster you go.
Sorta like a dyno for the cylinder head.
Or carbs etc.
you measure,make changes ,measure,make changes, again and again etc.
Almost as much fun as 71 dyno runs! ;) ;D Bill

so during the porting process the flow bench is  measuring  what is done. Is that all it does?

If I'm not mistaken it can also be used to bench sync the carbs...

Well, not necessarily; there can be too much of a "good" thing. ;)

A sewer pipe flows very well but it doesn't work very well as an intake or exhaust port. ;)
