| 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. | Sleeve: The sleeve has 9 transfer ports and an exhaust with booster ports. The piston features a new special black superficial treatment that reduces friction and improves piston strength. | Crankshaft: The crankshaft is grinded to increase the mixture flow and has a special shape to reduce turbulences inside the crankcase. The balancing is done by 3 inserts made of tungsten alloy and the inlet has a silicon filling to reduce the weight of the crankshaft to improve acceleration. | Gasket: 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. | |||||||||||||||||||||||||||||||||||||||||||||||

| 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. | Rear Cover: 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. | Glowplug: 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. | Compression rings: The ignition timing is controlled with these little rings of various thickness. To change the ignition timing you can add or remove a ring of a certain thickness. | |||||||||||||||||||||||||||||||||||||||||||||||
