The HF Thor 200 and Thor 190 breech modification kits arrived
These kits, composed of an Air Conveyor and a Spark Cooler have been previously tested by us in competition, and reduce the temperature under candle up to 50 °.
With the drop in temperature, the engine is more regular.
This will allow it a better durability.
Special prices for all Macfly pilots :
- Thor 200 Kit:
Special price TTC 240 € (public price incl. VAT 340 €) + shipping
- Thor Kit 190
Special price TTC 70 € (public price TTC 105 €) + shipping
The new design of the “HIGH FLOW” cooling shrouds combines the now existing air forced system with fan, the extraction generated through the propeller and the specific design of the cooling shroud.
This system, together with the SPARK COOLER lets the lowering of the engine working temperatures.
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.
