Thank you Charles,

A quick comment on something other than the helmet restraint topic. I see that the equiv. displacement rule for rotary engines has finely been made to something reasonable. The multiplier is now 2 times sweep volume, it was 3 times. This is making me reconsider the power plant for my future lakester.

Hmm!    Tony

It's liable to get noisey out there.

I love that noise!

Its not noise, its music.  Kind of like Beethovan's symphony #5.   8-) Tony

  I may have posted this before, but in the seventies I was lucid enough to remember a guy from Portland named Terry Hoard, who drag raced  a car called the Samuri Warrior.
 What a horrendous noise, sort of like a nuclear washing machine run amouk with no bearings left.
When he reved (or expanded or whatever the f--k those things do), dog's died, women became sterile, men more insane, and I left for Bonneville.
 I am afraid if that motor was brought to Bonneville that a giant chasm might open up and swallow all the fuel burning roadsters for life!!!
 Only ear doctors and hearing aid specialists will benifit from allowing these monsters to drown out the memories of Chauvin or Leggit warming up.

I agree with Bob D,,,  there is no joy in hearing a rotary rev up... nothing compares to the lope of a V8...

Those Rotary engines may be fast and rev to the moon, but they sure do hurt the ears...

But run'em if'n you got'em.

Way back when I had a Mazda RX4 -- the four door sedan.  I remember showing how smooth was the engine - to a buddy.  I'd have it in "park", open the hood, and have him hold onto the hood at the far front end -- farthest away from the mounting hinges.  I'd rev it to 7 grand -- and he would be amazed that there wasn't any vibration anywhere along the 0 - 7,000 curve.  The car, for a four door family grocery getter, was quite spritely, too.  Ah, those were the days, hey?

Maybe I could move exhaust to the driverside for everyone in the pits to hear, nope they will still hear me coming down the track!

I'd always heard that the incentive to drive a rotary fast was to outrun the damned noise.

[Plan B]

Owned a couple of Mazdas in the mid-seventies. RX-3 coupe and an RX-4 wagon.
Driving one was kind of like a Buick GNX. Not much noise or drama for a few seconds, then all of a sudden you were going really fast.
Horsepower graph was dramatic and peaked at a high RPM.
They came with an over-rev buzzer that was set at 6 or 7 grand, something like that.
Talking racers, I learned that the object was not to avoid the buzzer, but to keep it ON! That kept the engine in the narrow power band.
If it goes off ... add more throttle or downshift!

I'm not a big fan of the typical belly-button Pacific rim cars but the rotary does have a certain appeal.

Now back to the original, seriously high-jacked thread.

Ask the starters what they think of the noisy little ear drum breaking POS.

[Stainless1]

I think Marlo had one in the lakester back in the Monastery bus days, with a blower that was larger than the motor

Maybe they could move the exhaust into the drivers compartment.  That would get rid of roatarys even quicker!!!!
