CR = boost
CR = boost What compression ratio to run what amount of boost? A chart would be nice. Something like. CR 10.5 IC 7lbs non-IC 5lbs
Mostly want to know what CR is needed to run D1SC at 12lbs on lt1 on pump gas no meth at full timing.

I found this.
Correct Compression Ratio = FCR minus [(altitude/1000) x 0.2]
Compression Boost (in pounds per square inch)
