Was I insulting? I didn't think so.

The C-STR930 is the regulation cam for the Miglia boys. How cams work and what influences their best performance envelope is way to difficult to get in to here. There's something on my site about it. But the main reason the Miglias achieve such rapid acceleration is because they are on 3.9 final drives and taller first gear ratios than you get in road boxes, 10" wheels and very sticky slicks. They run their engines to in excess of 8,000rpm. Not something you want to be doing with your 1430. Race engines work in very different performance envelopes to road engines.

just to second what Keith says: Maintaining traction in first gear with a powerful Mini race engine is a real challenge on anything but super wide, super sticky racing slicks. The increased power and low final drive definitely contribute to impressive 0-60 times, but it would all be quite impossible without these grippy tires.
