Cosworth V8 - 20,000 RPM And Not Exploding!

youngoldy · 11 Aug 2005, 17:52 (Ref:1380031)

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?

By chopping 2 cylinders off a V10,would you believe.

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://tentenths.com/forum/showthrea...light=cosworth

No, it was Cosworth, go on http://www.cosworth.com/downloads/co...a6b661beb2 and you can see a video of this being done. Trust me, its brill (brilliant for all our non english talking people

)

**Adam43** · 11 Aug 2005, 18:11 (Ref:1380049)

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?????????

Its not its is definatly ferrari that have done this I remember when Ford said they are selling cosworth the head of cosworth said to carry on testing on V8 blocks and things.

Marbot · 11 Aug 2005, 23:11 (Ref:1380283)

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.

johnh875 · 12 Aug 2005, 01:02 (Ref:1380325)

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!

FPV GTHO · 12 Aug 2005, 05:50 (Ref:1380387)

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.

Oaksnaf · 14 Aug 2005, 12:24 (Ref:1381873)

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.

next season when running the new v8's what will be the min weight limit???

95 kgs.for the engine.Total minimum is still 600 Kgs as far as i know.

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.

This will make Formula 1 lose its position as pinnacle of motorracing. From 2006 the engine regulations will be more and more comparable with IRL.

I don't think the average viewer gives a toss about the engine configuration.

F1 will remain the pinnacle of the sport.

I don't think the average viewer gives a toss about anything to do with how an F1 car is put together,so long as the end result is worth watching on a TV screen.

The average viewer will give a toss, if it results in lose of competitors. A Formula 1 with only three engine manufactors isn't really fun.

Kicking-back · 14 Aug 2005, 18:51 (Ref:1382084)

Some of the greatest days of F1 only had two engine manufacturers

And those days were when?

**Adam43** · 14 Aug 2005, 19:03 (Ref:1382097)

I'm not saying either way, but I guess k-b is generally referring to most of the '70s. The DFV days. It was only really Ford and Ferrari.

Even in the 1970's Formula 1 had at least three engine manufactors. But I don't really consider the 1970's as special. The teams were still semi-amateurish and the sport was unsafe.

Personally, I consider the 1980's and early 1990's as the best era of Formula 1. And I think most fans agree with me.

**Adam43** · 14 Aug 2005, 19:24 (Ref:1382108)

I'd say mid to late '80s.

and there were tonnes of engine manufacturers! Although there are still potential for good races even if there are only a couple.

Kicking-back · 14 Aug 2005, 19:28 (Ref:1382116)

Still the potential for good races even if there's only one!
