Maxy's Cinco BT Tuned 5 Port .21 Off Road Engine (Ceramic)

The Novarossi Cinco BT Tuned has all the same great features as the Cinco BT but also has a high quality rear ceramic ball bearing for improved efficiency and longer life span. It also has a further modified crankshaft by Maxy Velazco for even more all around power and fuel efficiency.

The Novarossi Cinco BT is the evolution of the famous S21P5XLT engine, but with Maxy Velazco's Specs to further improve its potential. The Cinco BT features the redesigned 'Lighter & Lower Evo2' cooling head that lowers the center of gravity of the engine and chassis, as well as improving cooling efficiency. The sleeve has been reworked, lowering the fuel consumption and producing more power. The tuned crankshaft spins on a high quality 25.80mm rear bearing that was selected for improved performance and lifespan. The piston design features Novarossi's 'Compact Combustion Technology', providing increased efficiency. The piston has been machined for improved performance and life span over a cast piston. The Head button has an o-ring to reduce vibration. The new Cinco BT gives the power of the BONITO.21-7XLB with the fuel efficiency of the PLUS 21-4BTT for the best all around engine for any Buggy or Truggy.

Features:

• Cooling Head: The 'Lighter & Lower evolution 2' type cooling head has been drilled and milled out to reduce the mass of the cooling head, reducing the Center of Gravity of both the engine and car.
• Conrod: The R7 conrod is made from a super light aluminum which has been ultrasonically tested. The shape of the R7 rod reduces turbulence inside the engine while running.
• Piston: The material of this piston has been chosen for its excellent strength to weight properties. The shape of the top of the piston features Novarossi's 'Compact Combustion Technology' which improves the efficiency of the engine. This piston is also milled from a single block which further increases the strength.
• Sleeve: The sleeve has 5 transfer ports, the best compromise to make linear power with minimal fuel consumption.
• Rear Cover: The rear cover optimizes case volume and reduces dead space.
• Crankshaft: This engine has been "Factory Tuned".
• Rear Ball Bearing: The rear ball bearing has high quality ceramic balls to minimize wear and inertia to improve acceleration and fuel consumption
• Carburetor: The carburetor is made from plastic, in "reverse" style and has a sliding throttle valve.
• Combustion Chamber: The combustion chamber is supported by an O-Ring which is placed between the combustion chamber and the crankcase to reduce the vibrations of the combustion chamber.
• Glowplug: The C6TGC 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!
