2500 HP V-16 by Chrysler from WW II

My father is an air power nut and is crazy for this era. A bit of knowleage has rubbed off on me as wel as a like for the era aircraft.

This particular Thunderbolt was the faster ever produced. (I'd need to look up top speeds to be accurate) I think top speed was top 450 MPH. I think it toped at 472 MPH. For a piston driven aircraft, this is extremely fast.
Aircraft design, and engine have it's limits.
Engine RPM and ultimate power output and wing design are probably at it's max here. (Mostly wing)

Chrysler also produced engines for tanks. A weird design , designed to run even if a bank of cyilders were to be knocked out.
