W/r/t "big cam bleeding off cylinder pressure"
It does reduce CCP... all the way up to 3,000 RPM (more or less, depending on too many variables to list, but stops well before the torque peak).
After that, it increases cylinder pressure - that what it's for.
It doesn't always need 5 seconds to "build heat", the piston damage can occur in 1 second.
Dead on.
I've driven high compression motors on the street using not enough octane, with the plan being to stay out of the throttle. The question is do you have enough a self-discipline when an impromptu challenge arises? I don't.
It's like being alone in a motel room with a lingerie clad super model and agreeing not to look at her.
