Design of the Lotus type 907 engine.


Recommended Posts

Forum member Mike Brewer (cbclotus) descovered this technical document on the Lotus type 907 engine, written by the then Engineering director of Lotus, the late Tony Rudd.

Published by the Institution of Mechanical Engineers in 1973, it covers some interesting points on the design and development of the engin, and reveals some of the problems that had to be overcome.It clears up a few myths and missconceptions that have been printed about the engine in the past.

Thanks again for Mike allowing me to post this interesting document on the forum for all of us to share. :lol:

looking forward to having enough time to read it :lol:

I got to see how different the 907 actually is from the turbo engine up close, care of John (Esprsplt) Who's also a great guy :(

Think we both came to the conclusion that we wouldn't mind trading cars :D (At least that's the conclusion I came to) Even with the engine out on his car!

Went to an IMechE lecture by Tony Rudd in Coventry where he talked about the V8 engine. Didn't get a copy of the paper, though.

Sadly, I never got to see him or hear him speak.

Was it an interesting lecture Trev? :huh:

I marvel at that BRM H 16 engine he designed (with a pencil) :D

Yes, it was very interesting. It was one of those lectures that packed out the meeting hall at the Leofric Hotel in Coventry. Many of the lectures had about 10 people listening but Tony's was as popular as one the Patrick Head gave. And I can remember more about Tony's than Patrick's. In fact I wrote a precis of it and send it to CLub Lotus for their mag but it never got published. So much for my journalistic career. :huh:
