When I had my motorcycle tuning and repair shop in Long Beach (Signal Hill)
I used to hang out a Jerry Branch's whenever I could. I'm fairly certain I
misplaced most of my high frequency hearing ability somewhere between his
Dynos and his monster flow bench.

Subject: Re: air benchs
A friend and I built a bench that used a turbo off of a large Komatsu
tractor, with a 3hp single phase motor we could test at 20" at low lift and
12-13" at higher lifts with sbc heads.
I feel that guys that can't test to at least 20" might be missing out on
being able to hear when the air starts tripping over the short turn radius
and therefore not being able to know when it is close to being as good as it
can be. I hope eveybody is making use of some sort of velocity probes, in
the manifolds also.
