another thought, if you do the same engine work i.e. mods to a L20 and a VG20 which will go the best in a 510? ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, November 13, 2001 4:14 PM Subject: Re: V-6 or 4cyl? > The theory behind engine configuration is about balance and packaging > > A 'V' engine (except v12) is fundamentally unbalanced. i.e they shake and vibrate because all the rotating and reciprocating components are not fully balanced. > V engines are compact, this is their advantage. > > An in-line four cylinder also unbalanced - but you can add two balance shafts to compensate > > straight 6 engines are fully balanced for most harmonics, that is why BMW still use them when a v-6 would be lighter, cheaper, and more compact. > > Flat 'boxer' engines are fundamentally balanced and use a very short, and therefore stiff, crankshaft. > This is why Subaru and alfa-sud engines are so smooth and responsive compared with inline fours. > > Straight 8's are fully balanced but the crankshaft is long and not torsionally stiff and you'd need a long engine bay to fit it all in > > PS just because some engines are smoother than others it doesn't mean that they can't go just hard > > Nick > > > > > so can you explain why? > > > > > > Drag cars are v-8's because noone makes straight 8's... > > > > > > If your theory is true why aren't all motors Vees? > > > What about the boxers? > > > > > > > > > > > > -----Original Message----- > > > From: James Marmont [mailto:[EMAIL PROTECTED]] > > > Sent: Tuesday, 13 November 2001 12:08 > > > To: '[EMAIL PROTECTED]' > > > Subject: RE: V-6 or 4cyl? > > > > > > > > > no way!!!!!!
