Allow me to mention the greatest of all time, the Porsche 917 K30 developed for the Can Am series. If any of you recall the notoriety of the series was the unlimited class of the cars or just about show up with anything, it was the race of the big boys like the Chaparrals and so on, Porsche decided to enter the race with their 917 cars with a flat 12 4.7 liter engine, as they were not sure if the car would have enough meat Porsche developed a very out of character for them a 7,5 liter engine as a backup, but the highly supercharged engine proved to be so successful that it cleaned the races and in no time it was banned and the bigger engine was not needed, Porsche retired the cars to museums.
In 1973 I went to Dallas to see the car which was on display after the race, a few years ago I had the chance to talk to Hans Stuck at the Daytona 24 hrs, the old German pilot was still racing competitively, he used to drive the 917 back them, at the time the aerodynamics of the 917 were ahead of their time, even so at 220mph it was taking more than 800 hp to cut thru the wind, this being part of the conversation.
Back then the 917 was equal in 0 to 60 to a dragster with times in the 2 sec mark, keep in mind that a dragster is only capable to run for only a few seconds while the 917 had to run for hours.
Mark Donohue convinced Porsche to let him take a museum 917 to Talladega for an attempt to a record in a circuit, which he set a 213 miles (I think as I am going by memory) later on he said about his modified 917 that at 250mph he was still accelerating before he had brake to take the banks, at full boost the car was developing over 1500hp.

The record was broken a few years ago by an Indy car due to better aerodynamics.

that is an amazing race car! I just adore the 'ahead of it's time' Porsche engineering, especially on racing grounds.
