This is the Ultimate M-5 Tuned Engine. The M-5 engine is a 5 port engine, long-stroke, tuned crankshaft and has been configured for all those drivers who look for a powerful and linear engine with good power at both low and high R.P.M. It stands out an over sized cooling head to improve performance at high temperatures and it is easy to tune. The Ultimate M-5 makes excellent bottom end power, and is an excellent choice for 1/8 buggies and trucks This engine includes a R7 conrod made from super light aluminum and designed to create the least amount of turbulence inside the engine. The sleeve has 5 transfer ports to create a linear power output and to keep fuel consumption low. The tuned crankshaft is manufactured with a larger bore intake to increase the mixture flow, and has a special shape to optimize gas-flow in the engine. The rear bearing has a outer diameter of 25.80mm and has been used in order to avoid ring distortion and to increase lifespan.
