Beetles (and other air-cooled VWs) are indeed capable of carrying Porsche-derived or custom-built engines, which, when either fitted with a turbo system or a supercharger setup CAN produce 500bhp. Some special race-prepared modified old VWs in Europe easily pass this, but all this requires a hell of a lot of work and by God, you could certainly tell by looking!
This Beetle, while it may be nice, ain't got more than 44bhp!
