Breakage of all sorts has been our nemesis at Street Car Super Nationals, usually in the first round of qualifying. (We lost T-top Coupe’s engine on the first hit in 2009, and a 4.10 ring gear in our New Edge project Pony the following year.) It appeared we could be on the same path at the 2011 event when the blower belt snapped just beyond the 60-foot mark (1.54 e.t.) and ended the run. For the record, yes, it is difficult to simply break a cog belt. Further investigation found a loose bolt in the head unit, which caused the breakage.
