Alright..I know that lower comp. motors are boost friendly. How about us guys with higher compression? I found a chart on this link:
http://www.holley.com/HiOctn/TechServ/TechInfo/SCTech.html
If you scroll down it shows a chart that shows what effective compression you will have given your static compression with a given amount of boost. What I want to know is that if you have a motor which has a static compression of 8.5 and you run a blower with 12 pounds of boost you will get a effective compression of 15.4:1....according to the chart. Well, if I have a motor with 11:1 static compression and throw 6#'s of boost at it, the chart shows that my effective compression would be 15.5:1...basically the same effective compression.
Am I way off base by trying to look at a chart and figure if 6#'s of boost would work with my motor?? I know that my motor isnt "boost friendly" but does that mean it wouldnt work?? I have a Powerdyne possibly on it's way here pretty soon....
