"Despite its reputation, liquid nitrogen's efficiency as a coolant is limited by the fact that it boils immediately on contact with a warmer object, enveloping the object in insulating nitrogen gas."

Just answered my own question I think!

@Richard Do you know of that show...Wheeler Dealers? They call it that here in the states. Two blokes that buy cars..then fix and sell them. Tall guy named Ed and a stocky dude named Mike?

Richard, Cosworth like many more before and after them have their share of contributing to the F1 engine but technically speaking what is regarded by experts as the one to have started it all/showed the way forward re engine technology is very seldom mentioned and very little known, I have hinted about it on the page you were talking about push rod engines but it went unnoticed,
The year was 1913, the engine Peugeot L3 3litre four, the radical ideas came from racing drivers Jules Goux, Georges Baillot and Paolo Zuccarelli the interpretation of their radical ideas (engine design) was by the then 26 year old Swiss engineer (Geneva born) Ernest Henry who had contributed to the advanced Swiss picker engine that powered racing hydroplanes, the design was the first of any kind to combine a vee- inclined four overhead valve gear driven overhead camshafts with finger tappets.

eddie. yeah. i watch it but dont really like it! odd, i know, but watch it. they are only doing superficial jobs to keep a car running, but dont actually restore it. they never clean the undersides or do any real restoration. they got a couple of yank cars, such as dmc, chevy bel air. pick up. if they replace, say a damper, they would not bother to clean any other suspension parts etc.
i just watch it for the old cars.

@Sunny

"In 1966 Dan Gurney commissioned Weslake Engineering to build an Aubrey Woods designed 3.0 litre V12 Formula One engine for his Eagle T1G."

Is this the same engine/design that Ford thought would replace the Cosworth in 1970? Thanks! Ed


@Richard Copy that but I like it. Maybe its the language being spoken! Ha! :o

Eddie, you were correct about liquid nitrogen boiling when contacting hotter parts.
Some weeks ago I replaced sixteen 100mm diameter water cooled exhaust valve seats in a set of eight MAN marine cylinder heads, these valve seats have an interference fit of 0.25mm so they have to be shrunk by liquid nitrogen to install, when they are placed in the liquid nitrogen and it starts to bubble (boil) they are ready to install.

Well, apart from the Cosworth league back in the days, is there another manufacturer to have with three different outfit in a season.

It's true the alternator issue cast a slight shadow but in the end it's a third straight title and some valuable landmarks were also reached, so I'd call it a rather satisfying season for the Renault boys.

As for the top end power, it's always the same, it's one of the parameters that an engine delivers, on a whole season in current F1, it doesn't seem to be the absolute most important.

Renault never had the most powerful engine in the 90's, in the 00's and now, it didn't prevent them from winning. There are other important aspects and especially power delivery, torque curve, sobriety and thermal efficiency.
