Is that you and your Camaro?

It is darn near race car loud. The two movie clips are of my car.

Yep.

I hope this isn't too stupid of a question, but:

What is the purpose of revving your car like that, while you are parked?

I don't know how loud race cars are.

Pretty dang loud, I guess.

A lot of guys who had not heard the car in person, and were thinking of running a similar exhaust setup wanted to hear it. So we needed to give them a range. Just out of curiousity, where are you from?

Doesn't all that noise indicate some serious inefficiency in the design? All that wasted kinetic energy dispersed as noise, instead of directed as thrust?

It's kind of hard to explain where I am from.

My legal address is in Las Vegas, Nevada. Currently, I am in the Southern part of California's San Francisco Bay area. Mostly, I just travel.

what's a good camera for outdoor wildlife shooting? i have a nikon d70 but havn't used it for much other than family shots.

So, you're a speed junkie?

Is there anywhere you can go to take your car really fast? How fast do you like to drive it?

No, the exhaust gases exiting cause no measurable thrust on the vehicle. Engines are basically big air pumps. The more volume of air the exhaust sytems can carry, the lower the resistence on the pistons as they move, therefore more power.
