Can you hear the dump valve very clearly with thew addition of the GSR induction Kit?
Any sound clips?

Its not a dump valve you hear. Its just as the air gets recirced back into the induction you then hear it through the filter.

You can hear it with just a K&N panel filter..

ok

?

Didn't think T-Jets had a dump valve

They have a recirculating one.. If you look at the engine its on the induction pipework after the maf/map sensor and runs along the top edge of the engine cover and feeds back in before the turbo.
