alcoook, stock cars make the compressor stall noise also. Increasing boost will make it loader but lots of turbo cars can do it with stock boost levels. A stock fiesta rs turbo, but with a cone filter will do it.
A astra GSI turbo with the recirculating Dump Valve shut off will do it. As do Cosworths with a cone filter.
funnily enough though the MFI escort rs turbo cannot do it whatsover.
