The O.S. Speed B2103 Type S Buggy Competition Engine with the T-2100SC Pipe gives you the advantages and options expected of a competition grade power plant. O.S. has created a product that will evolve to meet driver preferences and course layout.

This model has a re-designed crankcase, engraved with the "O.S." Logo featuring an updated cooling fin with enough surface area for effective heat dissipation that gives the buggy engine a powerful look. This S Type has high vertical finned, low-profile cooling head with low gravity for improving the cars handling. The crankshaft has been updated to optimize the rotational mass and follows the O.S. SPEED tradition with a DLC coating to reduce friction, dual tungsten slugged counter-balance and a ceramic rear bearing to reduce vibration and increase RPM. The inner head has a silicon O-ring for improved vibration reduction and better dust resistance, and a three port sleeve that will perform well at medium and low speed ranges.

This engine also features the 22D carburetor which emphasizes quick response and smooth acceleration. This combo includes a T-2100 SC tuned silencer with M 2004 (85 mm) exhaust manifold, 6mm and a 6.5mm venturis, and a re-designed ball link which allows a change in the position of fixing screw for easier access

This engine is an excellent choice for buggy. Sent it off to Adam Drake for ebis break in service and it runs perfect. The linear bottom end and extremely powerful mid range makes the car very controllable out of the corner and allows easy set up for the next section while not disrupting the car very much. Highly recommended. Coupled with #DRAKEIN service
