For a short time, Curtiss-Wright CW-21 Demons were part of the AVG.
In Erik Schilling's book, "Destiny"* He mentions taking a CW-21 Demon for a ride.
He was astonoshed by the performance. CAMCO owned the plane and was using it to tool up to build 33 CW-21's for the Chinese government.
A light plane with a 1000hp 2 stage supercharger - it was a high performer.
Shilling wrote that he tried to get Chennault to obtain some of the Demons to shoot down high flying Japanese recon planes. He didn't write what the outcome of that was.
However Wiki says:
"The three Curtiss-built aircraft were shipped to China in May 1940 and were eventually handed over to the 1st American Volunteer Group (Flying Tigers), who intended to use them to tackle high-flying Japanese reconnaissance aircraft. These crashed and were destroyed, due to poor visibility, on a flight from Rangoon to Kunming on 23 December 1941. Of the 27 to be assembled by CAMCO, none were completed before CAMCO was forced by advancing Japanese forces to evacuate its Loiwing factory to India in 1942."
According to Wiki, a total of 62 were built and some were used by China and others by the Dutch East Indies Army Air Force.
Wiki entry has some interesting comments about the plane. It was designed to be an interceptor designed to shoot down bombers from a standing start with minimal notice and therefore was not to be used to dogfight opposition but to escape by its 5000+ fpm (according to "Destiny") climb rate.
Another interesting comment was by an Army Air Force test pilot testing the CW-21:
"Although the CW-21 was not commissioned by the U.S. military, it was test flown at Wright Field in Dayton, Ohio. The Army Air Corps immediately rejected the aircraft, with one officer commenting that it took a genius to land it."
* I have a signed copy of Shilling's book and had one extremely interesting phone conversation with him. Nice guy. One source says he was a clandestine pilot early in the Vietnam war. But he didn't write about that in his book. At the time I spoke with him, I believe he was building a biplane to fly. IIRC a Steen Skybolt. Or maybe a Starduster, Alas, like so many other WWII veterans he has Gone West.
The CW-21's 1820 engine had a two speed supercharger, not a two stage.
