CSL engine - advice sought! - Page 2

Hi,

NZ_M3-

The Mader development was carried over into
the Renault F1 Lump, although strictly speaking
its not a S62 Cast block as such.

All the development work that Mader carried
out on the S62 V8 Block project which they more or less
got for free when BMW dumped the project,
evolved into much of what Renault now run in F1.

No, it was not so much a cost consideration by
BMW, but the firing order of a Flat Plane Crank
V8 is different to a Cross Plane, and as such it
creates much more vibration which would have
to be dampened out for a Road based Car.

BMW missed a trick there, they should have released
a BMW M3 V8 but with a Flat Plane Crank, a
Transaxle, as they now run in the ALMS, and called
it a CSL, and at 130k plus, they would have been
queing up to buy, for sure.

Ferrari V8 to a point, get away with Flat Plane Crank
as the engine is in the rear, but on the Maserati V8,
basically same engine, except they revert back to a
Cross plane Crank, as the engine sits up front.

Listen to a proper M3 GTR just hitting the sweet spot
and there is no mistaking a Flat Plane Crank V8.

This is how to drive one-

Compare that to our GTR with the S62:

p.s. this was a test day a couple of years ago with very worn rear tyres!

Mr Gorilla

I don't know, still not convinced that there's a correlation between the BMW S62 (or P60 rendition) with the 2010 Renault F1 lump. That's about as credible as calling the M8 S70 V12 a dumbed down version of the McLaren F1 S70/2 V12 when Rosche himself have said they are completely different motors.

There's probably more commonalities between the S62, P60, S65 and P65 than a Renault F1 engine. To call lineage to it seem a little over fetched to me (you could then almost call all internal combustion engines having the same original lineage in that case). The fact of the matter is the 2010 engine is Renault design and Mecachrome assembled - it's not and never was an evolution of the BMW S62 (at least I can't find anything to back such a claim up). The GP2 motor was S62 derived and it is clearly well known.

I am aware of the issue and engineering differences between a flat plane crank V8 and cross plane crank V8 - I said it was a cost issue because BMW preferred a smoother road motor without added counter weights and engineering needed to balance out the secondary vibrations in the flat plane (which Ferrari have done quite successfully).

But yes you are correct, would have been superb if when they made the CSL they stuck the P62 in there with the flat plane crank

Great video comparison though!!
