The Geiger Z06 biTurbo is Truly a Monster

Geiger, one of the best tuners for Corvettes, has created an insane Corvette Z06. Modifications under the hood include: upgrading the cylinder block, heads, crank and increasing the displacement of the 7.0L LS7 engine to 7.6L. Next, Geiger added two "high-output" turbochargers with extra airflow at both the intake and exhaust ends to help keep the engine cool and hopefully not explode.

What does all of this give you? 890hp (664kW) at 6,100rpm and 694lb-ft (940Nm) of torque at 4,500rpm. According to Geiger, this Z06 can reach a maximum speed of 220mph (354km/h).

Geiger has added its own GT body kit to provide a lower, meaner look that doesn't mess with the Corvettes' lines and let the turbos breathe easier.
