A recent new addition to the Drag Evo is the Turbosmart Power Port blow off valve. Our old aftermarket blow off valve couldn't handle the boost we were trying to run.
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.
This should do nicely in helping us to run the boost we want :)
