Wally, it's a 700P. It packs 350hp a side through twin turbo'd 540's. And you're right, goes like **** out of a shanghai. The only Aerostar to come with 400hp engines was being developed by the factory back in the mid seventies. The engines were twin turbo'd IO-720's. It was to be known as the Aerostar 800 and there was only one built, but Ted Smith died in 1976 (it was his baby) and the aircraft never made it to production.
The Corsair looks superb. Going by the cowl it looks to be an F4U-5N. In combat trim the R2800 in these things ramped up to 2850hp at takeoff when everything was working as it was supposed to.
So if one had to choose between 2,850hp and 700hp....
....2,850hp wins every time! Beautiful.
