I was in a track event at Nashville Superspeedway with my old engine (just over 400 rwhp) and they got me on radar on the front straight at 147 passing a Porsche. I went to 5th gear as I went around him and about the time I pulled back in front of him all hell broke loose!! Concrete track, 9 quarts of
oil, Racing slicks and the rest is priceless!!
