What’s better than a top-of-the-line, $161,000 2011 Audi R8 Spyder 5.2 FSI Quattro? A supercharged version making over 700 horsepower. And what can possibly top that? One with a full warranty, of course.
The heart of Stasis Engineering’s Challenge Extreme Edition R8 is a bolt-on Roots-type supercharger (running at 7.5 psi) that adds another 185 horses and 132 pound-feet of twist to the 5.2-liter V-10′s 525-horsepower bottom line. A separate supercharger cooling system helps in reducing any power loss and keeps everything running smoothly, while a custom T-305 stainless steel exhaust saves 30 pounds and bellows deeper. The whole setup is commanded by a reprogrammed ECU.
Total power output on this mid-engine monster is an astounding 710 horsepower and 523 pound-feet of torque. As for performance gains, Stasis claims it takes just 3.1 seconds to reach 60 mph from a standstill.
Grip and handling improve as a result of 20-inch forged single piece wheels wrapped in extra-wide Michelin Pilot Sport PS2 rubber. Higher rate springs matched with beefier anti-roll bars limit body roll and keep all four corners planted. With 710 horses on tap, it shouldn’t be too hard to guess why Stasis offers 15.3-inch front and 14-inch rear two-piece Alcon brake rotors with matching calipers.
If all modifications are bought and installed at an authorized Audi dealership, owners are protected by a four -year/ 50,000-mile plan without their Ingolstadt warranty being revoked.
