SX15 EV-4 Features
This new line of NovaMega engines is manufactured for Serpent by NovaRossi, Italy. This entry level 2.5cc engine combines extreme reiliabilty with superb power and ultra smooth power delivery. This non-Turbo is the perfect engine to power your Impact or similar car.
Crankcase
The engine case and heat sink head are made from new special types of aluminium that are created to have ultra-efficient cooling properties without sacrificing strength.
This alloy dissipates heat better than regular aluminium, the engine can in some cases run with a leaner air/fuel mixture to provide increased power with far less risk of overheating.
The case has extra cooling ribs. The crankshaft is better supported and excessive vibrations are prevented and have proven to be very durable and reliable.
Cylinder head set
The cylinder head consists of two pieces, a separate combustion “chamber” and a finned cooling head. The combustion chamber is made of an alloy similar to that of the cylinder sleeve, having the same characteristics to improve the construction.
The construction totally seals off the compression chamber to provide the highest possible compression and thus max. power.
Crankshaft
The crankshaft is a 13mm diameter, precision crankshaft. The intake through the crankshaft is optimised to allow a continuous flow of the vaporised fuel/air mixture into the crankcase. Ultra strong ultra smooth long wear piece.
Carburettor
The Evo 4 comes with a fully adjustable 6.5 mm heat insulated aluminium carburettor. The special aluminium used for this carburettor improves cooling and the consistency of your needle settings.
Piston/Cylinder
The cylinder uses true ABC construction (aluminium piston, brass sleeve with chrome plating) for ultra–long wear. Of course, ABC piston/sleeves take longer to break in, but the benefits of longer life with better piston/sleeve fit is well worth the effort.
The conrod is the new ultra aerodynamic `R1´ type for higher revs and smooth power delivery.
Sleeve
The sleeve features 3+1 porting, delivering good torque at low revs, a powerfull midrange and very good high-end revs.
Backplate
The crankcase backplate is made from Aluminium. No fuss, long life item.
