2 The new ball bearing reduces the inertia of the rotating masses and increases the engine s scavenging. These novelties give an increased throttle response and a higer top speed. The new three tuning needles gives a better idle and improves the ability of the engine to return to low rpm after throttling. engines LINE R EXPLODED VIEW LEGEND 9 ON NEW COOLING HEAD NOVAROSSI WORLD S.r.l.

14 The sleeve has 7 transfer ports and an exhaust with booster ports. The special shape and positioning of the ports, covered by a patent, improve the internal fluid-dynamics to obtain the maximum possible performance. The crankshaft is grinded to increase the mixture flow and has a special shape to reduce turbulences inside the crankcase. This a Lighter&Lower evolution 2 type of cooling head. It is drilled and milled out to reduce the mass of the coolinghead which sits high up in the car and thereby lowering the Center of Gravity of the engine/car. The rear cover presents a round shape to optimize the filling and reducing the dead spaces. the steel plate is to reduce friction and to expand the lifespan of the conrod. engines LEGEND.25 The inner shape of the gasket has a new shape, and with that more material. Together with a change in material these gaskets are more resistant to high temperatures.

16 The glowplug of engine is a Turbo type glowplug. Turbo glowplugs have a different shape than Standard glowplugs and therefor are not interchange able with engines that are using Standard glowplugs! The new tuned crankshaft gives the engine a better balancing. This will reduce the vibration produced by the rotating and the alternating masses.
