Who really cares how it happens… just keep doing it!
Big single turbo R32 makes some beautiful flutter sounds! Most people have the wrong idea about turbo flutter! It sure does sound amazing, but it can be bad for your car. The makers of the video supplied a few updates as there were some errors in the making!
We accidentally say “Blow off valve” during the video at one point when meaning “Throttle body” closing, this is obviously an error. A blow off valve helps alleviate the pressure in the intake during closed throttle surge, “blowing off” excess boost.
IMPORTANT SECOND UPDATE:
We touch on the difference between open and closed throttle flutter. As an additional bit of information here, it was pointed out to me that closed throttle flutter is actually known as “reversion”, whereas open throttle flutter is more accurately called “compressor surge”.
Both are technically compressor surge, and both sound essentially the same, however the different conditions under which they occur are important to identify.”
