Rudy Frasca's 190 is a replica. Like the Flugwerk replicas, Frasca's lacks the strength of the original. Thus, this replica is derated for max g loading. In this case, 5g max sustained is the limit. Being built solely for use at airshows, 5g is well above what it would see.
Part of this is the power on tap. Powered by an R-2800-52, it has 2,500 hp available with ADI. Originally flown with a standard DC-3 prop, it was later fitted with a revised C-47 Glider Tug prop of much greater chord. These props have been cut to more closely resemble that used on actual 190s.
This 190 was raced at Reno some years ago, and the propeller limited performance. The new prop substantially improves performance and its usual pilot, John Maloney, believes that it would be very competitive in the Bronze class. The airframe stresses of racing are high, and I don't know if it will race again.
