[QUOTE="04sleeper, post: 16983409, member: 34911"] EcoBoost is a smaller engine with variable cam timing and knock sensors that actually work. Along with having factory widebands onboard and running in open loop to be able to make corrections quickly. With the variable timing, they also use HDFX with multiple timing tables based on different cam positions that switch based on conditions. This is what allows them to run more CR. You really have to calculate static compression to determine boost level safely. This would take into account piston CR, along with cam timing and overlap. Then you could calculate how much boost you could potentially run on 93. Higher CR works well on a lot of applications so you don't have to spin the blower as hard (ie, more heat) yet still yield the same static CR. The more CR, the less boost you need to achieve the same static CR. Hope this helps. [/QUOTE]
