You are missing the point and I don't have the paitence to type out 6 paragraphs to make it clear.So again, I ask the question, if lowering the compression and increasing the air charge is indeed the magical solution, then why not just lower the compression to 1:1 and have a giant compressor slamming 25 bar of pressure into the motor?
If it is a turbo car then yes, I would want as much compression as the motor will tolerate out of boost then live with the reduced ign timing under boost. The reason is turbo cars only make boost under load and most street driving is out of boost.In the end, I'dd personally rather make 1000 rear on 17 lbs of boost at 12:1 than 25 lbs of boost at 9.5:1.
On the street with a PD blower I would want to run lower static compression and more boost for the peak pressure reasons engineer mike pointed out.
And I'll have a 100,000 mile engineThat's just me. You guys do what you want.
