Turbo NOISE

[Syonara]

Questions--
This is going sound werid/stupid I'm sure, but--ive heard different turbo sounds, not from the bov, but from the spooling down of the turbocharger. Do ceramic turbos sound different?? I have heard a dodge conquest with a aftermarket turbo, and the down spool sounded like the helicopter form the show AIRWOLF. It was sick! Almost like the car was making a louggie sound.

Any info guys??

Re: Turbo NOISE

The air filter setup has a lot to do with it. If you take our stock setup, its relatively quiet. Put a cone filter in the end of the stock orange elbow, and you'll hear 10X the whine.

Best sounding one I've heard is on windedv6!!! What size turbo is he running? Probably no air filter at all when he's at the track either huh? He has some track videos on his sig that are awesome!

Re: Turbo NOISE

This wasnt a spool up turbo noise tho--

Re: Turbo NOISE

maybe he had an external wastegate?

Re: Turbo NOISE

I agree, most likely had to do with an external wastegate.

Re: Turbo NOISE

External gates are loud, but they seem to make the most noise while they are regulating boost, not after you let off the gas. This spool down noise is probably some turbo shudder you are hearing coming through the intake.

Re: Turbo NOISE

could it have been stock wastegate, open downpipe/exhaust dump? Will's old Ty sounded awesome with the exhaust dump open after letting off the gas. Made it the spool/downspool mean sounding.
