Mercedes-AMG’s sexy GT sports car gets a 456-horsepower base model for the 2017 model year, priced from $112,125.

But if you’re willing to pony up some extra cash, you’ll be able to drive away in a custom version spitting out a supercar-worthy 745 hp.

California’s Dime Racing, a motorsport engineering squad and now vehicle tuner, has teamed up with Mercedes-AMG to offer a GT with 745 hp and 731 lb-ft of torque—all for an estimated starting price of $150,200. The cars will be sold at select Mercedes-AMG outlets in the United States and limited to just 100 examples per year. They’ll also be offered with a bumper-to-bumper warranty.

To extract the extra power, Dime Racing installed bigger turbochargers, recalibrated the ECU and improved the cooling. The company also upgraded the aerodynamics, suspension and wheels to match. The modifications are based on lessons learned in motorsport, particularly the Pirelli World Challenge.

Each vehicle will be catalogued and serialized with its own Dime Racing-specific VIN, helping to ensure collectability and authenticity. Dime Racing will also throw in a car cover and a Växjö watch from former Formula One driver and 1999 24 Hours of Le Mans winner Stefan Johansson.
