Turbo noise

I think the noise your referring to is from an after market dump value, that release air to the atmosphere. Very easy to fit.

No, not the dump valve, I want to here more of the turbo boost but the PPPPLLLLUUPP noise haha, the PSSHHHHHHH haha

So Max, what is the baffle thing I might look into that. Have you done it?

There should be a baffle thing in the exhaust apres the turbo.

PLUP? PSHH? My classic 900 kind of makes those noises :)

If you want more whine (the high pitched jet engine noise), remove the turbo silencer. If you want more exhaust burble (the TVR kind of noise), then you'll need a different engine alignment!

I bet you'll find what you're looking for here:

I haven't removed it personally, since I don't own one of these cars (I will in a couple years, but the classic 900 can suffice for now) anyway, remove the downpipe from the turbo. You will see this thing stuffed in there, it is a sort of cylinder with raised parts of it, known as "turbocharger silencer" or turbo baffle.

There is one way to hear more turbo noise - put on the optional sport exhaust system that was once standard on the Classic 900s. You can also drive through an underground concrete parking garage. The concrete walls, floor and ceiling echoes the engine sound nicely :-) The floors are usually slick enough to easily squeal the tires.

Put on a aftermarket turbo from a detroit series 60 or cat engine.Be very careful it may blow your cylinder heads off LOL.

Don't worry, with all that mass to get rotating, the lag would prevent it from ever getting up to speed. Er, "LOL", that is.
