No guard rails, no run offs, rock walls and 1,000-foot drop offs. These factors make the Pikes Peak International Hill Climb a global draw. With their sights set on the 2013 “Race to the Clouds” Pikes Peak event, the road-racing specialists at Evasive Motorsports put together a proposal to Scion Racing. According to Evasive Motorsports’ Tony Kwan, “Our ten years in business have revolved around road racing and street performance. We wanted to build a hill climb car and Scion’s FR-S looked like the perfect platform to attack the mountain.” Scion Racing approved the project and Evasive Motorsports received its FR-S just eight weeks before the…

Learning curves affect horsepower curves, so as Javier Loarca can attest, with greater knowledge comes greater horsepower. Loarca had raced an all-motor pro class car for a number of years. There he learned about making power without boost or nitrous oxide. When his all-motor racecar was sold, he purchased this Civic EG hatch as a commuter in 2007. But a short matter of time brought him back to racing as he sought to do something a bit different. Not only would he embark on a forced-induction journey, he would do so with Honda’s newer K-series powerplant instead of the B-series…

While the ignorant V8 “Mountain-Motor” camp still spouts the “There’s no replacement for displacement” mantra, various methods of forced-induction have proven to be the perfect substitutes for cubic inches. Turbochargers, along with positive displacement and centrifugal superchargers, have allowed small-displacement engines to multiply their naturally-aspirated output. When the desired power increases are on the order of 50-to-100-percent over the “all-motor” output, a properly-sized and wellengineered turbocharger or supercharger system can generally provide the desired performance increase without a significant tradeoff in engine response. However, when the output of the engine is going to be doubled, tripled or quadrupled, a big…
