Jacking around w/ the latest dyno #s, old dyno #s, old track results, and the other stuff that's changed... I THINK the MoPig "should" be capable of squeaking into the 10.1s at 129+ MPH. But reality has a funny way of changing hopeful expectations...
Now that I've put it out there publically, the laughter may begin.
No laughter here, just waiting with GREAT anticipation for you getting the car running & at the track
