O.S. Speed Engines for 1/8th Off-Road

The Finnish 1/8th Off-Road season has already started and the results from the first race already speak for the dominance of O.S. Speed engines. Lockdown of the top 5 and overwhelming majority representation in the top 10. The most popular of the top end engines is the B2103. The engine comes in two different models (Type R and Type S) and the difference between the two models are porting on the cylinder liner, the carburettor and the cooling head.



B2103 Type R

The more popular one of the B2103 models is the Type R. This engine has a high cooling head, 5 | 3 port cylinder liner and the 22E carburettor. Due to its larger amount of ports it has slightly more power on mid range and high end. The 22E carburettor is based on the O.S. Speed 21J carburettor that has been proven as the best option for years. This carburettor is very easy to tune and produces a very linear power curve. The high cooling head produces good cooling and the engine keeps very stable temperature even on hotter days. The Type R is our teams number one choice for Finnish Off-Road tracks.

B2103 Type S

The Type S represents a more modern direction of 1/8th Off-Road engines. This engine has a low cooling head, 3 | 1 port cylinder liner and the 22D carburettor. Due to the low amount of ports the Type S produces more torque on bottom end and has better fuel mileage. The 22D carburettor is a new O.S. Speed carburettor which is made to get better fuel mileage and a smoother throttle feel. The low cooling head gives a lower center of gravity to the car and helps the handling on more higher grip tracks. The Type S is best suited for higher grip tracks that require good bottom end torque and fuel mileage.

O.S. Max Engines

The more budget friendly options of the O.S. Engines catalog are the Max series engines. Both of our models 21XR-B and 21XZ-B are a great option for 1/8th Off-Road and the 21XR-B is also great for the 1/8th GT class. Both engines are based on the O.S. Speed top models but don't include the DLC coating on the crankshaft and the carburettor is a more simple design. For a hobbyist both of these engines are a great option and why not for a racer on a tighter budget.

O.S. Speed Exhaust Pipes for 1/8th Off-Road

The O.S. Speed catalog includes 3 different types of exhaust pipes with different length manifolds from 70mm to 90mm. The most popular option is the TB02 with a 75mm manifold. All exhaust pipes have their strengths and are suited for different circumstances and driving styles.

TB01 EFRA 2042 (T-2060SC WN)

This pipe is the oldest of the O.S. Speed models and for that reason a trustworthy choice. Soft torque on the bottom end provides good driveability and a neutral power range. This pipe is usually used with a 75mm manifold.
