Well for all the Dinan lovers and haters here is a link on youtube from M5board talking about a future stroker V8 for the M3 that is basically the M5/M6 stroker V10 with 2 cylinders knocked off.
Dam impressive.
As another tidbit, check out the vids from M5board and the development of the CAI for the V10, an impressive amount of effort and true "design" work to make it breathe better. A lot of effort for 20 hp but it shows what work it takes to develop a product like this. Performance without sacrifice.
Enjoy.
