A clip from a 1981 F1 documentary focusing on the on Williams team and the use of the Cosworth V8 engine. Footage I've not seen before.

Never forget that first place goes to the racer with the MOST laps, not the racer with the FASTEST lap

Great video. I don't remember having seen that one. I have a VHS copy of "The 1967 Ford-Team Lotus" video that chronicles the design and development of the original Cosworth/Ford four-cam V-8. Plus I have copies of the TASS books on the design of the DFV, and the Jaguar V12. TASS is a British engineering publication that often has articles about auto engine design.

 

One of the many tidbits of car trivia I have collected over the years pertains to how the gears in the cam drive geartrain are designed and fitted to eliminate all backlash. Using the usual gear tooth clearance specs, you would end up with as much as 15 degrees of timing variation, due to the stack-up of the clearance of all the gears.

I have a piston from a DFV that came from the Monza Gorilla car at Long Beach. I used it as a pencil cup.

A "simple" engine with >3,500 parts! LOL. Relativity.

 

One of the greatest racing engines of all time. What a glorious sound!

 

An illustrious career in F1. (It was 15 years before turbos made it obsolete!) The DFX variant dominated Indycar racing and the DFL was a capable sportscar engine that won LeMans in 1980. In F3000 it won over half the races it was entered in.

 

Quite remarkable.

Yep... The Indy version for years was the DFX. The first Indy versions in the '70s were stilled called DFV though they were resized to 2.65L vs. the F1 DFV that was 3.0L if I remember correctly. The resized DFV then became the DFX.
