10 - 50hp piston engine Thor 200 EVO

10 - 50kgfor paramotor2-stroke

Polini THOR 200 EVO engine grants many improvements thanks to the new following features: • New transfers and exhaust diagrams • New head drawing with embedding in the cylinder • New crankshaft with filling inserts • New cooling shroud • Modification for the Walbro carburetor All these mechanical improvements concretize in advanced technology, better performance, and extraordinary weight/power ratio and above it is possible to exploit all the engine power. The cooling has been improved after a careful inspection of the air flows for the engine cooling and thanks to the new cooling shroud which keeps the operating temperatures under 10-15% (in standard conditions) increasing the engine reliability. Two are two models of carburetors available, with bowl or Walbro carburetor. – Bowl carburetor proved to be really performing with a constant power output at all rpm, contained temperatures and reduced consumptions. Furthermore it features a torque increase and a wider engine range. Now the engine reaches 8000-8200 rpm. (It is recommended the use of a propeller with more pitch to better exploit the engine trust that the new Thor 200 EVO offers) – for Walbro carburetor the opening of the throttle valve has been limited: this has allowed a torque increase and a smoother power output. The maximum engine range is 7400-7500 rpm and it can be reached faster compared to the previous Thor 200 model. It is not necessary to use a different propeller.
