10.2 : 1 compression 360 at sea level. Options?

Imathinkin' that the idling engine just ain't gonna fill the cylinders the same; the cylinder filling with a closed throttle is always just a tiny fraction of at WOT. And things are happening at a lot faster rate than when cranking; the cylinder filling just has to be less with the shorter time periods involved..... the mixture has to be accelerated from a dead stop each time, and the shorter the actual valve open time, the less will get in.

Bottom line is that we do the cranking pressures at one speed (and WOT) and this is is at a speed 3-4 times higher with a closed throttle, so for the pressures to be different should not be a surprise.

I really don't see the fuel washing as a problem as the fuel should stay pretty well suspended.

But, hey, that is just the way the 'visible v-8' model in my wee brain works LOL
