I hear differing stories on compression. Many state the standard rule of lowering compression and running your boost. Some have bolted a procharger on a 10.5 compression engine and ran VERY well. There is a local guy who did this with a small block demon (10-1 I think). The power impressed/scared him. No long term report good or bad on this plan as far as engine longevity.
