Errrr . . . No. The block WAS externally identical, but the 2.5 version had a larger bore and longer stroke. Think original Chevy V8s - 265 and 283. Externally identical blocks, but different internally, where it counts. Countless other examples are available.xpensive wrote:Conceptual wrote:Sure thing, it those heads somehow changed the bore, stroke or both.I know that my first car had a 2.2 turbo (Dodge Daytona) and later their minivans ran with a 2.5 turbo.

So in that case, there catually IS a .3L increase simply due to the head design.
Yes, it’s the swept volume by the piston(s) from TDC to TDB that people usually refer to as volume or capacity.xpensive wrote:Gentlemen,
The last time I checked, the cylinder volume of a piston-engine is defined by cylinder area times length of stroke, hence "volume".
Empty volume at piston's TDC can decide the compression ratio, but not the cylinder volume, unless I missed something fundamental at university.
I think this happens because the process of designing a new matrix/casting dies for a block is complex and expensive. Maybe they only change internal sandbox.donskar wrote:Errrr . . .

Agreed, VW or Hyundai could purchase Cosworth for around 60mil and rebadge the engines as VW-Cosworth or Hyundai-Cosworth as Ford did in the 90's.WhiteBlue wrote:Now I wait to see who currently owns Cosworth. I would not put it past some of F1's sharks to silently aquire a controlling interest in the standard engine supplier. Both Briatore and Mateschitz would be good for such a move in my view.
It as been known since months that Renault would support the standard engine move. Renault has all but shut down their F1 engine department and to have it to revive could be the straw that brakes the camels neck for Goshn.
Except that badging isn't allowed according to the tender. But as a first step to an assault in some years when cost have settled down it would be a terrific investment by any new automotive company.Shaddock wrote:Agreed, VW or Hyundai could purchase Cosworth for around 60mil and rebadge the engines as VW-Cosworth or Hyundai-Cosworth as Ford did in the 90's....WhiteBlue wrote:Now I wait to see who currently owns Cosworth.
