The new Revmaster R-2300 (2331cc, 142.2 cu.in.) engine maintains Revmaster\u2019s famous proprietary systems and parts, including its RM-049 heads that feature large fins and a hemispherical combustion chamber; and it maintains the earlier R-2200\u2019s engine\u2019s top horsepower (82) at 2950rpm continuous. (Takeoff power is rated at 85, at 3350rpm.) The additional power ultimately comes from a bore of 94mm plus lengthening of the R-2200\u2019s connecting rods, plus increasing the stroke from 78 to 84mm, but that is oversimplifying things.\u00a0 \u201cWe have put a lot of energy into this redesign,\u201d says Joe Horvath, President and founder of Revmaster. \u201cOn paper it looks like just a few minor modifications, but we\u2019re really closer to a complete rework of the internals: crank specification, rods, pistons, and cylinders are all new.\u201d The longer stroke results in more displacement and longer connecting rods yield better vibration and power characteristics; the lower cruise rpm allows the use of longer propellers \u2013 and the higher peak horsepower can be felt in shorter takeoffs and steeper climbs. Strength and reliability are ensured by Revmaster\u2019s 4-main-bearing crankshaft that runs on a huge 60mm center main bearing and is forged from 4340 steel, with nitrided journals. Thrust is handled by the 55mm #3 bearing at the propeller end of the crank. Fully utilizing its robust #4 main bearing, the Revmaster crank has built in oil-controlled propeller capability, a feature unique in this horsepower range; non-wood props are usable with these engines. The direct-drive R-2300 retains Revmaster\u2019s famous dual CDI ignition with 8-coil spark to 8 spark plugs, dual 20-amp alternators, oil cooler, and its proprietary Rev-Flo carburetor, while introducing the longer cylinders that do not require spacers. The automotive-based bearings, valves, valve springs, and piston rings (among others) make rebuilds easy and inexpensive, even as the Revmaster-engineered components have heavy-duty longevity built in. First deliveries have already begun; full production is underway. Pricing for a complete, test-run Revmaster R-2300, complete with geared starter, dual ignition and twin alternators.
