no to all
D-type: what do you mean with "laid over"?
I mean the engine tilted about it's axis to lower its C of G as it was in the Cummins Diesel and the Belond Special at Indianapolis or the Brabham BT55 in F1.

Yes, the Black Hole is open to all puzzlers. Usually the reward for solving a Black Hole puzzle is 2 points instead of one.

Post by: gte4289 on October 22, 2023, 02:19:28 AM: Matti Holtzberg and the first (2.0 liter DOHC) Polimotor engine

"Torlon® has been used to manufacture a molded plastic gasoline engine. The Torlon® polymer was chosen because of its strength, toughness and high temperature resistance. In 1982, with the looming oil embargo, the Ford Motor Company entered a joint program with privately held Polimotor Research Inc. to develop and with the objective to manufacture a plastic car engine by the late 1980s."

"The 2.0 liter, dual overhead cam plastic engine developed by Polimoter Research, Inc. utilizes Torlon®, an injection moldable thermoplastic made by the Amoco Chemicals Corporation. Weighing in at 175 pounds and developing 3118 brake horsepower at 9,500 rpm, the engine is 200 pounds lighter than its steel counterpart."

I think the stated power output is probably a bit optimistic. :) (Should read "318 brake horsepower.")
