239 | Do You Need a Blow Off Valve?

Blow off valves and turbochargers have gone hand in hand for almost as long as the turbocharger has been in existence. There’s various theories about the requirements for the blow off valve, including the ability to reduce the thrust load on the turbocharger and prevent expensive failures, and releasing the pressurised inlet charge air when the throttle is closed to help reduce lag or improve spool when the driver opens the throttle. In this webinar we’ll do some investigation of our own and analyse what the data shows us using our Toyota 86 fitted with a Borg Warner EFR6758 turbo.
