Plastic automotive engine
Version one was based on Ford's 2.3-liter Pinto engine and weighed (vs. for its cast iron counterpart). It was designed to produce at 9200 rpm. It was composed of metal cylinder sleeves, metal combustion chamber tops, metal piston crowns, bearings, valves and seats, and a stock 2.3L Pinto crankshaft. Nearly everything else in the engine, including the block, rods and piston skirts, were made of glass reinforced Polyamide-imide thermoplastic resins manufactured at the time by Amoco Chemicals Co. The engine was never installed in a vehicle.
American Jet Industries T-610 Super Pinto
The T-610 Super Pinto started off as a 1968 conversion of the United States Navy's Temco TT Pinto two-seat jet trainer. AJI modified the aircraft for light attack by changing the powerplant with the General Electric CJ610-6 turbojet engine and extending the fuselage by 10 inches. It featured a modified wing, wingtip fuel tanks and a swept vertical stabilizer as well as provision for two underwing hardpoints. The prototype first flew on June 28, 1968. The aircraft flew very well and now was three times more powerful, with only 20 pounds more weight than the original design. The United States Air Force (USAF) evaluated the Super Pinto during its PAVE COIN program in 1971, but had failed to gain any contract with either the USAF or Turkey.
