-W made a monster Turbo-Compound Radial that was at least 3600 Cubic Inches displacement, similar to the PW described above.
I believe you are referring to the Wright Cyclone 3350 which had 18 cylinders with 3 PRTs and with just 3350 cu inches produced some 3450 HP
in its final civilian mode. The P&W 4360 with 28 cylinders and 4360 cubic inches capacity produced 3500 HP
in it's civil mode and I believe 3800 HP
in military role. I have heard of the military getting 3800 HP
out of their 3350s also
These engines are great to look at and hear, but they must have been their owners nightmare as their reliability was very poor campared to todays jets.Still they did not know that then and the ingenuity of the designers to get a few more HP
out of their engine was amazing.
Mind you they were all renowned for their oil consumption with perhaps the 3350 considered the worst of all so I am told, and each engine on a Connie did not have a 45 to 50 gal oil tank just for fun. On the Super Connie they even had an extra belly oil tank so as to allow oil transfer to the engines in flight.
I have seen an old Connie Manual which stated that an engine should not be removed from the wing unlees it's oil consumption exceeded 5 gals per hour!
Those were the days none ot that little quart cans then rather 55 gals drums
