NEW “HF” – POLINI HIGH FLOW SYSTEM – FOR THOR 190 EVO AND 200 EVO ENGINES
“HF” system has been developed by the Polini R&D team for Thor 190 and 200 EVO engines. “HF” is the innovative system that grants better performance and optimize the cooling of the cylinder. Some prototypes have been used during the last 2018 French Championship by the the pluri-world champion Alex Mateos won the title, confirming its reliability and brilliant performance.
“HF” KIT TECHNICAL FEATURES
The new profile of the burning chamber improves the propagation of the flame optimizing the turbulence during the fuel combustion phase. This peculiarity, together with the increasing of the compression ratio, improves the engine performance reducing the fuel consumption.
CARBURETOR SET-UP AND AIR BOX (FOR THOR 200 ONLY)
The new set up of the carburetion has been improved thanks to a series of workings inside the carburetor finalized to increase the power output and the vaporization of the petrol/air mixture.
SCS is the innovative cooling system of the spark plug that lows the working temperatures in the point of highest grade of heat and in the burning chamber, eliminating the events of over-heating definitively.
The new design of the “Polini High Flow” cooling shrouds optimizes and accelerates the incoming flows and increases the exit power towards the propeller.
Polini HF kit, installed with all the its parts, reduces the EGT temperatures till 100 C° and till 60 C° the temperatures under the spark plug.
