Paul, have we checked how loud the VAM is with a proper

tailpipe?

Bill Jepson

No but we got 110 db with no tail pipe.


Paul Lamar

Understood, since you can see the exhaust
entries into the can without the tailpipe
I can see why it would be real loud! That
mixing area would really help noise wise.
Might not be a big improvement. It might
even be a help to thicken the wall at that
spot. Are you going to run it on the dyno
engine? Or did it go directly to Ken?
Bill Jepson

I could run it on the dyno as I still have it but I would have to
undo the runner extensions that Jerry Bass added so it could fit my motor
mount. It will eventually go to Ken when he is ready for it later 
this spring. It will work as is for Ken. Perhaps with a safety clip
or two. You don't want something that big going through the prop.
