Marlin,

The new cars go fast in a different way that's for sure. With all the over drives they can build a motor a little more differently "smaller cubes" so it can efficently work in a smaller power band using gearing to take care of the weaknesses. The stuff sure does last a long time and fly using the modern fuel systems.

I guess what I'm saying in the above thread is that overlap is as big of a component as duration for a rough idle. Ramp speeds will help determine overlap. Sorry for the confussion.
