I have dyno charts of both the .63 and .82 GT3076R on 100 octane on GST's dyno, I will post them tonight. If you plan on doing autox at all and you want to go rotated I think you will be choosing between the .63 GT3076R and the .82 GT3071R (I don't have a chart for this one).
If you don't want to go rotated I have become a GT52 fanboi, I will post my chart up later as well
