Studying engines, calculating hp, torque, efficiency, and exhaust flow for grades? Sign me up! It wasn't just the content, though, as magnificent as it was. The class itself was taught by the coolest prof there is. You may think you've had a cool prof, teacher, coach, or instructor, but I've got the standard by which all educators must be measured. For one, he or she has to teach something that is cool.. does it get cooler than Internal Combustion Engines? (No, in case you're wondering). This one is also a true gear head, so much so that he sticks around after class and argues about cars, performance, lap times, and racing. And occasionally does so in the middle of class.. For one class project, I proposed comparing the engines and specifications of the C6 Corvette ZR1 and the Ferrari 5...
I've been a huge fan of Michelin PSS tires and exclusively bought them for the Mustang over the last four years. So how did I end up here? This year, I was hugely interested in trying an "R-comp" tire. I had my eyes set on Bridgestone Potenza RE-71R's for two simple reasons: price and reputation. Although not a true "R-comp" tire on paper, it performs like one by the account of every single test and review I've read (down to wear rates...). They seem like they're easily the most affordable (from a big brand) R-comp tire and combine that with a reputation for having tons of grip, it was an easy top contender. I had my concerns, though. For one, I'm told and have read that they are an autox tire, not really designed for high speed, pressure, and temps associated with open track. For another, the Mustang is a heavy car (as far as track cars are concerned) being roughly 3,800 lb. (including driver), which will amplify the unwanted open track load...
