XSIVPWR Posted July 16, 2013 Report Share Posted July 16, 2013 Yes my the engine is stock, OP's is 60 over. That would be a cool chart to pin if somebody could find it. I'm sure it would be for stock engines but it would be a good guide. Quote Link to comment Share on other sites More sharing options...
