Possible inconsistent definition of Colombo engine edit

Latest comment: 17 years ago2 comments2 people in discussion

This page is inconsistent: in the intro it says that the colombo engines ranged from 1498cc to 3285cc, further down it mentions 3967cc, 4390cc, 4823cc and 4943cc versions. PerDaniel 21:24, 1 July 2006 (UTC)Reply

That might depend what is called a "Colombo" V12 engine. The original series Colombo V12 featured a 90 mm bore spacing (compare with Lampredi 108 mm), the offset between cylinder banks was 20mm (compare with Lampredi 22 mm) and the engines had shrunk-in wet cylinder liners and detachable heads (Lampredi design used screwed-in wet cylinder barrels and cylinder block/head were a single unit bolted to the crankcase) etc.

So it's my understanding that all those engines up to and including the 250/275 used most of the basic Colombo design including the 90 mm bore spacing.

However it seems that later V12 engines used ideas from both the Colombo and Lampredi series. But, possibly depending which "experts" you talk to, these are still referred to as "Colombo" engines as they are often seen to be considered an enlarged development of the Colombo, with wider bore spacing(?) and other changes, rather than being considered either an updated Lampredi design, or a totally new series of engine. So the inconsistant information might depend on how strict we are about what we call a "Colombo" engine... which is why we should cite sources in articles. --Xagent86 (Talk | contribs) 08:14, 9 March 2007 (UTC)Reply
