Ty Tessmann tore up the track at the 2014 IFMAR 1/8 Scale Off-Road World Championships running an O.S. Speed Tuned B2101 engine tailored to his winning specs. Now O.S. makes that same setup available to other drivers — in the Ty Tessmann Limited Edition Speed Tuned B2101. The engine features the same tuned pipe, manifold and carb restrictor used by Ty to win the 2014 IFMAR Championships. Its T-2090SC pipe is paired with an M2002SC manifold whose added length increases torque in the low to middle range. The 5.8mm restrictor — not available on any other O.S. engine — matches what O.S. supplied to Ty for extending run time in competition. Like the standard B2101, this version has a lowered cylinder head, DLC crankshaft with balanced tungsten weights, and a Type 21J carburettor. Only a small number are being produced, making this engine both competitive and collectible. The Ty Tessmann Limited Edition Speed Tuned B2101 is easy to distinguish from the standard model due to the natural-colour cylinder head and Ty’s name laser-etched onto the crankcase, crankshaft and tuned pipe.
