POLINI launchs the new HIGH FLOW (HF) system carried out for the R&D equipment in the THOR 190 EVOand THOR 200 EVO engines models.The HF is an innovating system which ensures the best performance and optimizes the cylinder refrigeration. Some prototypes of this system were used during the French Championship in 2018 for the abslute winer and pluri world champion Alex Mateos, confirming the reliability and excelent performance of the HF system.
HF KIT TECHNICAL FEATURES
“HF” COOLING SHROUD
The new design of the “COVER” cooling shrouds optimizes and accelerates the incoming flows and increases the exit power towards the propeller.
Together with the air forced system it grants great performance in terms of cylinder cooling.
SPARK COOLING SYSTEM
SCS is the innovative cooling system of the spark plug that lows the working temperatures in the point of highest warm and in the burning chamber, eliminating the events of over-heating. Polini SCS system reduces the EGT temperatures till 100 C° and till 50 C° the ones under the spark plug.
The new profile of the burning chamber improves the propagation of the flame optimizing the fuel combustion phase. This peculiarity, together with the increasing of the compression ratio, improves the engine performance reducing the fuel consumption.
CARBURETOR AND AIR BOX
The new carburetor set up 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. Two fuel systems are available: bowl Ø28 carburetor or Walbro WB37 carburetor.
The KIT POLINI HF KIT fitted with all its parts ALLOWS TO REDUCE EGT TEMPERATURES UP TO 100º, AND REDUCES TEMPERATURE IN THE SPARK PLUG UP TO 60º.
This HF Kit is available not only in ALL the new Thor 190 and Thor 200 HF engines, but may also be available to equip the previous thor 190 and Thor 200 Evo models with this system. You can consult with us…
