Anti-lag systems help a turbocharger to continue producing boost when a driver is out of the throttle, but did you know that the Subaru rally team had one that could fully spool a turbo at idle? The Subaru Impreza WRX STi S11 and S12 WRC generations featured a unique system dubbed Rocket Anti-Lag. Using patented technology from Prodrive and similar principles to a jet engine combustor, the cars were fitted with a separate combustion chamber in the exhaust.
The system that drivers like Petter Solberg and Mads Ostberg got to enjoy has puzzled people for some time, so I decided to read through the patent documentation and try to understand how it works. So let’s learn how anti-lag works, then go over all of the awesome engineering behind the rocket system! This is Subaru’s Rocket Anti-Lag explained!
