The early engines, V-1710-103, used on the 1st XB-42 prototype were with 1325 HP for take off, military rating of 1150 HP at 22400 ft; war emergency rating with use of water-alcohol injection ('wet') was 1820 HP. Max rpm 3200.
The V-1710-125 was rated for max rpm of 3200, that combined with 75in boost (dry? on 115/145 grade?) made 1675 HP for take off possible, with WER of 1900 HP on 75 in Hg 'wet'. Engine was spewing out oil when run more than 5 min on 75 in boost. Similar was the -129, used on the 1st flight of the second prototype.
There was also a V-1710-137 (four produced), with different pistons that brought compression ratio to 6:1, and take of power to 1790 HP on 100 in Hg, WER was supposed to use 100 in Hg of boost for the power unknown to me.
