These engine models differ essentially as follows: Model 2SD-G Basic model. 2SD1-G Similar to 2SD-G except has plain type main bearings, revised diffuser, impeller, ignition harness, cams, exhaust valves and guides plus the above listed differences. 2SD13-G Similar to 2SD1-G except has aluminum finned cylinder barrels, plus the above listed differences. D14 Similar to 2SD13-G except has 16:9 reduction gearing and an integral torquemeter. D3 Same as 2SD13G except has a single speed supercharger drive. D4 Same as 2SD1-G except has a single speed supercharger drive. D5 Similar to 2SD13-G except has a single speed supercharger drive with supercharger impeller and diffuser identical to those in the 2SD-G plus the difference listed above. D7 Similar to D14 except has a single speed supercharger drive with impeller and diffuser identical to those in the D5. NOTE 5. The following ignition systems are eligible in the pertinent engine models: High tension type 2 Scintilla SFLN-8 magnetos with integral distributors, high tension harness and spark plug leads. All Twin Wasp are eligible using SFRN-8 magnetos and the appropriate reversed direction gear train which eliminates the two-position spark advance. Such engines are designated by the letter "S" following the engine serial number. Low tension type 2 Scintilla high frequency type L-8992 magnetos, L-8998 harness and leads with BG-712HF transformer spark plugs. Requires two 1/2 speed magneto drives. Engine weight is reduced 24 lbs. NOTE 6. Twin Wasp D series engines are eligible for operation on Grade 91 fuel provided the following reduced ratings are not exceeded. High ratio supercharger drives, when available, should not be used with Grade 91 fuel. Takeoff 1100 hp at 2700 rpm. Maximum continuous 1000 hp at 2550 rpm. NOTE 7. The following spark plugs are approved for use on these engines: AC 161, 171, 181, 261, 271, 281. BG 240, 245, 340, 341, 345, 346, RB19R-2, RB21R-1, RB23R, RB27R, RB27R-1, RB39R.
