Well here's the results with 9lbs of boost on E85 pump gas. Not fully tuned as we ran out time on the dyno. Got to 27* timing but was still responding with each change and A/F was at 8.0 or 12.0 stoich.http://s949.photobucket.com/albums/ad340/jdspowdercoating/?action=view&current=20110909123253.mp4

Awesome results. Can't wait to see the final results. That seems like a good deal of timing for a boosted motor though...27*:eek2:

Will continue to :lurk: until the final results.

The miracles of E85! Would u mind listing the motor particulars. Head/cam combo etc.. I am about to build a 408 with a procharger.
