D3s 1001 hp Cadillac 1This matte black monster comes courtesy of the master fabricators and builders at D3 Cadillac in Signal Hill, California. Sure, they could have given this 2011 CTS-V coupe a blinged-out, boulevard-cruisin' stance and strapped it with a diamond-encrusted Louis Vuitton interior to unveil at the 2011 SEMA Show, but, what fun or challenge would that have been for the world's preeminent aftermarket tuner of Cadillac vehicles?

With well over 250 man-hours invested, the project has been ongoing since June 2011. The 6.2-litre Eaton-supercharged LSA aluminum V-8 starts life with 556 hp and 551 lb-ft of torque, numbers that arguably put it (or any V-spec Caddy for that matter) into supercar territory. But, the D3 brain trust had bigger plans for this vehicle, much bigger in fact.

For starters, the 427 cm³ powerplant has been CNC-machined, ported, polished, balanced and stuffed with more manly Manley connecting rods and Total Seal piston rings. It boasts a fortified valvetrain with D3-spec Isky cams, custom rockers, push rods and lifters, everything necessary to replace the standard 1.9 L Eaton blower with a much larger, more efficient and more powerful one from Kenne Bell that achieves 17 psi of boost on the street and can go as high as 28 psi for racing.  All told, the motor upgrades nearly double the CTS-V's horsepower and torque numbers, now estimated to tap out at 1,000 hp at 5,900 rpm and 1,000 lb-ft at 3,200 rpm, respectively.

Whiteline urethane bushings help reduce shift shock as all that power is transmitted to the staggered-width 20-inch Rennen wheels, which are painted gloss black and wrapped in sticky R-rated Toyo Proxes T1R tires, sized 275/30 and 345/25 in the front and rear, respectively. Behind a total of 40 spokes, the CTS-V's high-performance Brembo six-piston front/four-piston rear calipers and vented discs remain intact.

With the insane motor setup all figured out, the challenge for the design team was to go big and match it visually. In this case, that equals wide! As in a complete D3 custom sheet metal wide body aero kit that adds 1.5 inches to the front and 3 inches to the rear fenders to accommodate the 13-inch wide rear rollers and achieve the proper stance.
