"One specific problem faced by Adam and his tuners-of-choice, Autosport Werks and European Performance Labs (EPL), was how to get big horsepower from the twin-turbo 2.7 V6 while breathing the thin air at 5000ft above sea level. "Lots of trial and error with different turbo set-ups drove us crazy," said Adam, "but in the end, TiAL's 750 turbo kit and EPL's tuning did the trick." Yes, and quite the trick it is, too, with a Dyno Dynamics verified 528hp at all-four wheels. Keep in mind, this dyno is notorious for providing pessimistic numbers, and even factoring a conservative 15% drivetrain loss, we're still talking over 600hp at the crank.

Under that carbon Y-pipe sits a bored 3.0 motor with ported 2.8 heads and two Garrett GT28RS turbos with TiAL 2886 compressor wheels, helping to produce 528hp at all four wheels. There's more to building a 600-horse 2.7TT than slapping on bigger turbos, and Adam took a comprehensive approach to achieving his goals. Bigger is often better, so toward that end he upped the displacement to a full 3.0 liters by way of forged 82.5mm pistons and Pauter rods. The entire assembly was balanced, blueprinted and O-ringed to ensure everything stayed bolted together under multiple atmospheres of pressure.
