the power output of the car is not really relevent as you want the turbo timmer to cool the turbo and oil after a spirited drive or thrashing on a track so as to preserve the life of the engine and turbo, its the amount of work your turbo does which is the contributing factor not the power output of the engine, so if you only ever see 2-3psi of your turbo then there would be no point in one but if you thrash your car then get home you'd want to cool everything down, depends on the driver etc. :icon_thumright:a mate of mine uses one, and they seem quite good.
i think they are more usefull on higher power applications though.
ill try and find out the make and where it came from
