The Power Port is Turbosmart’s largest and highest flowing blow-off valve ever, resetting the flow benchmark set by our popular and highly regarded Race Port BOV. Designed to be as light as possible, to keep vehicle weight down. Its cutting edge dual-chamber design means it can be held open with the use of a solenoid to aid turbo response and control during staging to give the best possible launch. For high HP turbocharged or supercharged applications
