if setup correctly, the car will idle making almost full boost, so the moment u touch the throttkle you have full boost without having to wait for the turbo to build up to speed and pressure. on cossies though its fairly primitive and retards the ignition lots , throws lots of fuel in and its actually fuelling and sparknig when the exhasut valves are open casuing the turbo to get hot,
without a proper turbo with the correct shaft etc, u will fook a good turbo in no time at all and overheat it. u really need a temp probe in teh exhaust to monitor the temps. its used on rally cars, but i myself was going to have it donw, but speaking to people who have had it, they find for normal road driving it doesnt make any real difference, and is only really any good for showing off and scaring grannies as it goes bang bang
