RB CXR SLS9 super long stoke 9-port engines
RB continue to update their line of nitro engines and now introduce the CXR SLS9 super long stroke 9-port .21 on-road offering. First up is the SLS9 with 9-port liner, Multi Exhaust System technology and a CNC-machined piston. The engine furthermore features a 14.5mm turbo crankshaft with balancing weights, internal grinding and silicone insert. The 14.5mm main bearing is a ceramic ball race while the 6-ball front bearing is a standard steel type. The 3-needle carburettor comes with 8.5mm and 9mm venturi inserts and the engine is equipped with low profile cooling head and an O-ring sealed turbo combustion camber insert. Also new and building on the SLS9 is the SLSDI9 with direct intake technology for an even higher power output. The DI variant otherwise comes with the same features as the standard SLS9 engine and both are available separately or as combo sets including 2092 or 2015 in-line exhaust sets. The latter is specially designed for high-speed tracks and fits with RB’s short and medium manifolds for additional tuning possibilities.
