9psi / 0.6 Bar 38mm Wastegate Spring



38mm Wastegate Springs 9psi

All external wastegates have a wastegate spring inside them set at a certain psi rating which means the wastegate cannot let more psi in and go pass the springs pressure rating. If you are wanting to increase the boost in your vehicle the most stable way to do it is to replace the spring with a high psi rated spring. Of course this works in reverse if you are wanting to lower your boost. This is the best way to control your boost in your vehicle as it is stable.
