hmm? i thought wastegate is to bypass exhaust gas so your car won't go overpower or overboost? more like limiting the power for the health of your turbo rather than increase power.

dun quote me on that, i'm no turbo user.

wastegate doesn't increase power... just increases turbo response, and is more stabilized limiting boost.

STock torbo's also got internal wastegate... most aftermarket turbos don't have internal wastegate... which requires you to purchase and install an external wastegate.

yup..its to bypass the turbine to control the amount of boost to be produced by the compressor.

okay i should repharse it than.. haha depending on how much exhaust need to be release in order to prevent overboost some cars might need more than 1... hehe normally use 1 only... maaf bang maaf, or more accurately twin turbo engine.. so could use to wastegate.. correct now?
