Cosworth V8 - 20,000 RPM And Not Exploding!
How wos this possible? I don't even know how a normal bog standard road car engine works. Does anyone have any idea how they did this?

That was Ferrari wasn't it?
The Cosworth V8 that we have seen teh dyno test of was a true V8.
See this thread for a previous discussion on the Cossie V8: http://www.ten-tenths.com/forum/show...light=cosworth

er, the thread I linked to was all about that video clip.
Looking at that video again, how can you tell it is a V10 with two missing cylinders? I can't see anything on the website saying it is a V10 with two pistons missing?????????

It was Ferrari who ran their V8 in a V10 case,so not a finished V8.
My original post was just a generalisation of F1 technology,since youngoldy didn't seem to be too aghast by the fact that the V10s were reaching 18-19,000 rpm or simply didn't know.

I remember reading years ago about how an F1 engine if free-revved (ie no load) at wide open throttle for 10 seconds would reach 100,000 rpm assuming it held together that long. Note it was ~10 years ago so I am probably wrong on those figures!

On a similar note to that posted above, i'd be interested to see how the Cossie would go on the track, whether that 20Krpm target is still achievable without further work

I don't know about revs, but Honda's goal is 800 bhp with their V8.

The V8's will be running more than 20,000 RPM definately.
As far as HP 780-820 would seem like a fairly decent, if not great effort in the engine department. But it all comes with development. Engines/tyres will develop and before we know it, the cars wont be any slower and the rule book will be once again re-written.

I don't like the minimum engine weight. Formula 1 was always about innovations. For the engines, it was not always about more RPM or BHP. In fact, the search for weight reductions slowed the increase of power a little bit.

There are other restrictions such as minimum distance between cylinders and maximum bore.So you end up with everyone having pretty much the same engine anyway.
