Hirth F-30 ES Fuel Injected 110 HP 

The Hirth F-30S is the high performance version of the F30 80hp engine. F30ES is the F30S engine equipped with fuel injection. With nearly l hp to every pound the F30 has one of the highest power to weight ratios available.

Factory recommended TBO is rated at 1000 Hrs. @ 75% power. 

The F-30 incorporates Al-Nikasil coated cylinders for superior performance and reliability. Al-Nikasil in simple terms is a nickel based material, applied in a paste form, when super heated it becomes part of the cylinder itself.

Al-Nikasil provides for a super low coefficient of friction, reducing engine heat and wear. The pistons and cylinders expand at the same rate thus providing for a seizure resistant engine.

F-30 crankshaft is 4130 chromoly steel. Heads, cylinders, rings, block casting, connecting rods and associated components are all of the highest grade alloys available.
