If it blows off the wast gate well there's not much any over boost protection is going to do because if it cannot command the waste gate to open if it cannot supply boost pressure to the gate?Rev limiter will stop the engine revving out?

Say goodbye to your motor in this situation if the ecu cannot pick up that it has spiked to this much boost and cut spark to save the motor. A car with 25psi springs in the wastegates could spike to 50+ psi pretty quick and the ecu would be none the wiser of this happening.Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
