the noise isnt from the wastegate, it is the air pushing back through the turbine blades when the throttle is shut, you can get this noise if you remove the dumpvalve and block off the pipes but this is only safe on td05etc. hope this helps!

thought i was correct , but dja why is it only safe on td05 etc. i run a gt30r hybrid rotated i get it with atmos dv . think the problem here is snaped shafts as turbine is stalled by the built up pressue yes . but if a atmos dumpvalve releases the built up pressure then its not so bad as the rest isnt so built up and under as much pressure . so you just get a bit of surge which sounds good but doesnt do much damage . i thought if you block your original rc dv up it would stall turbo and you would be worse off as your turbo would stall and take more time to spool in next gear and this could snap a turbo shaft
