Here are the NER Solo sound rules from our web site:
* All vehicles participating in NER-SCCA Solo events will be
required to meet a sound limit of 90dBA measured at 75' at Devens and
94dBA at 50’ at NHIS. This may be measured from any side of the
vehicle at any time and includes such noise sources as intake noise
and tire squeal. Note that these two sound levels are virtually
equivalent. Vehicles which meet one limit should be legal for the other.
* Vehicles such as those in FM and CM which have a GCR-mandated
maximum length may exceed that length for the purposes of installing
an alternate muffler or exhaust system. The additional length may
serve no other purpose.
* After the first violation, the competitor will be required to
demonstrate that an effort has been made to reduce sound levels
before being allowed to make a second run. This determination will be
made by the event chair or a designee. If the second run is still in
excess of the allowed sound limit, the competitor will not be allowed
to make any additional runs at that event and the competitor will be
required to again demonstrate that improvements have been made before
being allowed to participate at further events.
* Event staff reserves the right to red-flag a car in excess of
sound limits and no re-run will be given.
* These sound regulations will apply at both NHIS and Devens.

John, the rule for mufflers has been waive by the NER SCCA. This
also covers any National Tour or Divisional held in New England at
our current sites. This was done because, if we didn't, many of
the people that drove many many miles to get to Deven's would have
had to go home after their first run. I will send you a few
pictures of various setups. Mine was the first Solo II Rotax done
for NE and as I have said, it is fugly. Geff Martone's is the
second attempt and I guess I just picked the wrong muffler. When I
have the money I will do one like his. But first I will try doing
what Vern did!

WARNING .. SCCA RANT ALERT!
And, of course when it comes to mufflers, keep in mind that our
incredibly inept SEB has still not approved an exhaust length past
the rear axle that would include any kind of standard stinger or
other muffler. This has only been an issue since 2002! What is
that, 4 years???? So if you're going to run any normal stinger/
muffler keep in mind that you're illegal, and if past penalties
are an indication you will be unceremoniously bounced from the
event .. no second chances. Just go home.
The SEB(solo events board) knows we REALLY use those mufflers
for .. more horsepower! Yeah, they got it all figured out. How
pathetic, how incredibly inept. But then I * All vehicles

guess that club racing hasn't tackled this thorny issue either.
I'm done now.

Jay that would be ok, but most of us in the real areas (New
England) that are currently having the biggest noise problems
still would like to see a 4stroke sled engine with CVT. Also, I
thought it was mentioned that someone, maybe Aeen was working on
a solution to keeping the noise down without having to ad a big
car muffler to our cars. A small Dynamax seems to work on the
newer 493 engine much better than the combination of my
Flowmaster and Aeen singer on my 494! I don't know if Aeen has
seen pictures of my setup, but it sure is fugly!

I am starting this thread to simply start a dialog on the
subject of
alternative drive trains, so do not send the assassins.
I am of the opinion that we need a 4 stroke engine with a
conventional
transmission for our class to survive. I would be happy with a
2 stroke
with a transmission but I do not think there is a production engine
available.
I am not saying that we eliminate the 500cc w/CVT combination,
but only that
we have a competitive alternative engine that has a conventional
6 speed
transmission.
I say this because we need to generate lots of new interest in
F500 or we
have a good chance of losing our national status in a few years.
Thanks ... Jay Novak
