Super chargers run hot, robbing volumetric effieciency and subsequent power. Cooler ambient air temps, cold dense air, good for power. We like that. Hmmmm. Opposite side of the coin. Performance tires and suspension in cold temp's on cold surfaces aint' good. No stick, rigidity, lots of slide. Go figure. Sometimes it's just nothing short of horsepower Nirvana going balls to the wall and turning the steering wheel. As said here before...how did we ever live without MRC? Hahahah.....we drove it like we stole it....and if we didn't get killed or busted, we got good at it...heheh...
