Talk:Pneumatic valve springs

Pneumatic valve springs

Both "Valve gear" or "Valve systems" are headings that I think obscure the issue, that of pneumatic valve springs, which I think would be a better heading for the section. I edited the section to get rid of hot rod jargon and unnecessary use of the definite article to improve encyclopedic style. If something got lost in the process, I would like to discuss it here. I don't know how many references are made to the present heading but it would make searching (valve springs) easire, since it is bellows type pneumatic springs that are described.

Pneumatic valve control is an advanced technology, but it is impractical because the cost of manufacture is quite high (we lack technology). —Preceding unsigned comment added by 207.138.102.224 (talk) 12:41, 17 September 2008 (UTC)[reply]

Renault engine most powerful in 80s?......Wrong!

The piece of the article that describes the Renault engine as "often said to be the most powerful", this is completely wrong. Everyone knew that BMW M12/13 engine was the most powerful from it winning Nelson Piquet the world championship in 1983, till 1986 when it is often quoted that the BMW engine produced over 1400HP, but there were some degree of uncertainty as engine dyno's at the time could only handle 1200hp. Even the page for BMW M12/13 engine on Wikipedia states it is "the most powerful engine ever used in F1". I find it rather annoying that pages on Wikipedia completely contradict themselves, and it is a little embarrassing. Therefore, I have edited the article to say "one of the most powerful engines", as this is more to the truth. I wish people creating and editing articles would do a little research beforehand...
