I try to fly something old and interesting each year. Last year I flew a Jet Provost and spent a couple of hours in this Hawker Sea Fury, which belongs to the Royal Navy Heritage Flight... It retains its original Bristol Centaurus sleeve valve radial, which cranks out about 2,500 hp. Most of the Bristols have been replaced by P&Ws nowadays. I believe that one of these aircraft still holds the unofficial speed record for a piston-engined aircraft at 547mph. "Standard" max speed is 460 - one of these actually shot down a MiG 15 in Korea. Regards Jon'.
