Hi,

In his book ?Firewall Forward?, Tony Bingellis describes a Swiss
Muffler. Have anyone tried it on a rotary. I?m thinking of using it on
my Vision to offset some of the weight of the 13B.

Regards,

Its been tried several times on the rotary. The rotary chews it up and
spits it out.


Paul Lamar ...No rotor no motor.

Paul,

At the show, they were running a car with a turbocharger that was very
modified and it was fairly quiet.  What are they doing for mufflers?  I
don't think a Flowmaster type with the reflector baffles would work because
the rotary doesn't appear to have the distinct exhaust pulses that a piston
does.  The graphs you've posted before show a lot of overlap of the exhaust
pulse even with the 13B.

I have no idea what those guys are using for mufflers. A turbo charger alone
quites them quite a bit.
