I would LOVE to do that, but there are two problems, a dissembled dyno, and simple minded rednecks. The rednecks would prefer simple minded categories, I'll try to avoid that. Even worse is that no one knows how to assemble or calibrate the dyno.

I know its only 6 cylinders. But its cheap, and really cheap to make loud.

A VW Jetta VR6 from the 90s. Here check it out.

Is this loudest by idling or revving or what?

Maybe, but the rotary will push the sound meter farther than either a V8 or a 4. Theyre always the first the get booted at tracks that have stricter sound restrictions.

After living on a racetrack for most of my life I have noticed that big block Chryslers as being louder than most everything else. Now, if you said irratating I'm sure it would be a Honda.

If you want loud you need Compression. Find someone with a 13/1 big block Chevy or Ford and run it with open headers.

The cars you listed will sound like pissed off weed eaters regardless of what you do to them. You want noise you need Cubes and compression.

Or a Twin Turbo car with a two step.. Either on will work just fine... Watch the video at about the 14 sec mark.

2 stroke diesel, obviously.

More cylinders the better, you can pick them up in an early Kenworth for about $3000. (Actually w/o turbo are easier to find and are much louder)

Jet engines are pretty noisy at the tractor pulls.

I have been to competitions where the 'Simple-minded-rednecks' show up with their $2000 Dodge Cummins with twin turbos off Bubba's Peterbilt that registered 800hp and 1200 ft lbs of torque BEFORE it broke the tie-down straps on the Dyno.

And you consider yourself "above" the simple minded? I have a 2000 hp dyno and yes, I know how to assemble and calibrate it. Oh btw it is better to have simple easy to understand categories, unless you want a lot of fights when winners are being picked. Unless someone shows up with a Top Fuel engine, your winner will have a big V8.
