Project Cappuccino is wonderful: The combination of light, well-balanced chassis, responsive turbocharged engine, and inoffensive body with convertible roof make for the ultimate toy. It’s an incredibly fun car and unlike most ultra-light sports cars, has a roof, doors, heat, and even a real trunk. It’s a wonderful autocross car, but there is a problem: we typically run with Miatas and CRXs. A CRX was rated at 106 hp and early NA Miatas came with 116. The Cappuccino started life with a paltry 63 hp. Even these lowly sportscars are making nearly double what the Cappuccino did and the Cappuccino only has a 400 lb weight advantage. A bit of extra power would therefore be very helpful in helping us close up on our competition. The easiest way of finding power in a turbocharged car is to reduce backpressure and suction losses, so we decided to look into ways of uncorking our intake and exhaust systems.
