Hello Mr Heng
I'm the guy who drove the blue Subaru 2WD, for whom you installed two Surbos on the 2nd of August. I've gained about 12% on mileage in spite of my 17" rims. As for torque, I could feel the difference when cruising in 5th gear. I've shown the installation to my colleague and he's quite keen to install it on his Impreza too. Unfortunately his is AWD and it's auto with 16" rims. Would need your advise if it's ok for his car as he's very keen to also have cold air induction like what you also did for me.

Note from Surbo Engineering: AWD (all wheel drive) is not a problem as most of the Imprezas we have done are AWD whether they are manual or auto. The fuel savings could be a bit less for cars with oversized rims as more of the torque gained could be used for acceleration. That said, the Surbo will still help the car somewhat, so please ask him to try the Surbo.
Watch the video above showing how an engine revs with Surbo. Or watch it with the How it works page.
