The software side doesn't concern me too much, as I intend to fit it to a set of E36 M3 S50 intake runners which have been adapted to mount on a two valve M20 which will be running Bosch purely mechanical fuel injection.....
But the noise and low intake losses interest me greatly, also, my two valver should sound better than the 24 valve cyl head.

The adaptors have been fabricated already before

Nice bit of fabrication there Marquis.

It retails at just over £3000 for the airbox alone (it's approximately 1 metre in length of pure hand-laid carbon fibre)

Ah! Thanks for that! In That case perhaps I should look into making my own! Perhaps when the time comes I could perhaps examine a CSL article as a guide...

Wouldn't the V8 actually be better balanced than the I6? after all the weight is similar and if the V8 is mounted as far back as the I6 then it will probably be shorter (4 cylinders long vs 6, ok that's simplistic but you get the idea).

Could be more weight up higher though with the V config? would probably be best to invert the V for best weight distribution. That would certainly be a different approach...

Would probably screw up the gearbox location though, requiring some tricky transfer case, wonder if they have tried it in F1?

r988, have you ever considered employment within central or local government policy making circles ? I think from your cogitations you may be well qualified

Surely there's more to it than that though

£3000 for a composite plenum

M3 CSL around the ring.

One of the best sounding cars ever...

I think it is great that someone has had the courage to V8 the CSL. It would be great to do a back to back with the modified car and the standard CSL. Oh all right, a CSL with some extra trickery, as the V8 has some add ons. Could the owner let us know what it is like and if the excercise was worth it.

Can`t someone enlighten me about this car. It must be hell of a tool.

The first principle of engineering ?

"Keep it simple"

That way it works...
