World Champion

This is the engine that powered Mark Pavidis to victory in the IFMAR 1/8 Scale Buggy World Championships
A first for model engines, the magnesium heat sink head weighs 15% less than aluminum and runs cooler as well. The specially coated crankshaft features a precision ceramic bearing that greatly reduces friction plus a Tungsten weight for added balance. Developed specifically for this engine and available separately, the T-2060SC WN tuned silencer (OSMG2938) utilizes a welded-on pressure nipple. A double adjustment carb allows for ultra-fine tuning for demanding race conditions.
