If there’s one company that knows a thing or two about tuning GM’s products, it’s Lingenfelter. The Indiana-based tuning firm has just announced its latest package for the Cadillac CTS-V series, which covers the sedan, station wagon and coupe models. In stock form, the CTS-V’s 6.2-liter supercharged V8 churns out 556HP and 551 lb.-ft of torque.

Lingenfelter’s engine tune includes a variety of mods such as ported LSA cylinder heads and the addition of LPE’s GT9 ZR1 supercharger camshaft, which help push the V8’s output to more than 700-horses at the crankshaft. The long-time GM tuner also tried out a CTS-V Coupe with a manual transmission on the dyno, with the test yielding 623HP and 617 lf-ft at the rear wheels. Follow the jumps for a video and detailed info on the tuning package.
