Novarossi 3.5cc Off Road Engine 7 Port Buggy"Rolling"

Coolinghead: 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 use of 6 screws instead of 4 ensures a better sealing between sleeve, botton head and the crankcase. Sleeve: 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. Conrod: The R7 conrod is made from a superlight alluminium which has been checked ultrasonic. The specific form of the R7 creates little turbulence inside the engine while running.
