external wastegate

You mean an external wastegate that's NOT plumbed into dumping into the main exhaust system, but which dumps to atmo? My Skyline does that, as does a single turbo Supra I have in for work. Someone on one of the Skyline firums has a vid with sound of a Skyline with one. IMO they are dreadful, mines being plumbed back into the main pipe. No way would a dump to atmo pipe pass noise checks on track days and they are a police magnet, as well as being naff, IMO, on the road.

what i want to know is this

 

at TOTB there was a white 200SX owned by (according to Japanese performance magazine) Richie Beaumont. it had the massive rear wheels and drag tires, with the street front wheels and tires. when it did a burnout and released the throttle there was a sound like a multiple dump valve, only more high pitched. i was told it could have been an external wastegate.

 

i have a couple of short videos if someone can host them for me. only about 10 MB in total

 

cheers
