Funny ain’t it; while Americans are still patiently waiting for the 362 Hp Pontiac G8, on the other side of the Atlantic, the Brits are being offered a supped up version of the HSV! As of this October, Vauxhall will offer a supercharger kit on the option list of the Holden Commodore HSV Clubsport R8 based, VXR8. The addition of the supercharger boosts the 6.0L V8’s output from the standard car’s 412 Hp (307 KW) to a massive 540 Hp while maximum torque is also enhanced by around 30 per cent.Vauxhall hasn’t released any performance figures but since the standard 412 Hp version with the manual gearbox sprints from 0 to 60 mph in 4,9 seconds we wouldn’t be surprised if it managed a sub 4,5 sec. time. The supercharger can be ordered either as an extra or it can be fitted retrospectively by any of you luck Brits who’ve already parked a VXR8 under your garage. Either way, the cost of the kit is £6995 or $14,100 and it comes with a three-year factory guarantee.
