That is a 1988 Audi 80 Quattro. A little modified Stock, it's a 2950lb AWD car.
This is from a bunch of crazy Audi guys that do all kinds of swaps/mods. The car in question is making way north of 500 whp on a 2.2L engine.. this is AWD as well so the crank hp is _way_ higher (AWD cars have bad bad drive train losses). He's running over 30psi of boost.
He's the guy behind 034efi.com (complete standalone system that is bolt-on for almost any Audi..)
