The Turbosmart Kompact Dual Port 25mm blow-off valve vents both to atmosphere and back into the intake, using sequentially timed ports to stay quiet during normal driving while delivering vent-to-atmosphere release under race conditions. The dual-port design balances driveability and the audible benefits of atmospheric release when needed, giving a flexible solution for turbocharged setups that need controlled recirculation and venting.
