Earlier this year RB released their RALLY 1/8 engine, designed for extreme conditions such as the cold winter months of racing. After a successful release of the original, RB has announced the RALLY V2 engine. The new version pays close attention to giving the RALLY engine more efficient power at low and high RPM using the latest technology. The new XTREM RALLY V2 receives a 7 port sleeve with MES and additional lubrication holes, machined lightweight piston, new turbo balanced 14.5mm crankshaft, and a new black coated crankcase. All-in-all the new engine is designed to be faster, more efficient, lighter, and even more extreme.
