I have a 2005 Porsche 911 turbo s cab. It makes an intermittent sound that seems to come from the right front of the car that sounds like when you blow over the top of an open bottle. I hear it most often when going about 40 mph, and it goes away if I rev the engine, but soon comes back. The dealer says it's normal for a turbo - something about sucking air through the gas cap area. I don't believe it, and the sound is very annoying. does anyone have any thoughts?

In short, unless you are dealing with a Porsche engine to start with, you will not have alot of success in duplicating the tone. There are a few factors that combine for the unique engine note... on the older cars you have a combination of the flat 6 configuration, air cooling, and the turbo. The newer cars are now watercooled and also quieter (with factory exhaust), but the engine layout remains the same and the basic layout of the exhaust system is still similar. If you wanted to closely replicate the sound with another engine, an early VW engine would probably be the best canidate (being both flat and air cooled)... then it would just be a matter of adding a turbo and finding the right exhaust. This is probably as close as you'll get without going with a Porsche.

Is the noise with the top up or down?
