So I saw this convertible 300CD, I have seen this one before, barely got a pic this time. And brown. I didn’t know what this SMS 570 was, but:
The SMS 570 Challenger (“570" refers to the car’s 5.7-liter Hemi V-8) begins life as a stock R/T. The car is then dismantled and rebuilt with SMS components at the company’s 150,000-sq.-ft. complex in Corona, California. The most important of these is the SMS 296 Supercharger system, which uses a Lysholm twin-screw compressor along with SMS’s Six-Pack Intercooler System. The last features six finned tubes that Saleen says make the system about 60 percent more efficient than traditional intercoolers. Combined with a cold-air intake and a free-flowing SMS exhaust, the result is 500 bhp at 5700 rpm and 500 lb.-ft. of torque at 3800 from 4.5 psi of boost.
