ProBoost is a company in Saarenkylä, Finland that makes turbo kits for motorcycles and snowmobiles. However they are also building a custom motorcycle. The custom chassis is built around the power plant, a 4.0 L BMW M60B40 V8 running twin-turbos. The 4.0 L V8 produces 282 hp and 295 lb-ft of torque from the factory so you can guess how much the twin-turbo version might produce.
