2007 Shelby Mustang GT500 Engine Failures?

This was shown to be a failure on an early engine, not the one about to
be put into production. Check The Mustang Source 2005 forums for a post
by one of the regular contributing sales people. He is a knowledgeable
and factual provider of information.

The sources are alleging that the GT500 crankshaft breakage can be attributed to two complimentary issues. According to our reliable sources, Ford designed a crankshaft damper specifically for the GT500, but the damper weighs in at a hefty 26 pounds.

>The weight of the GT500's damper, combined with the stress of the SuperCharger pulling on the crankshaft may be placing too much stress on the crankshaft's snout, which is causing the failures. By comparison, the balancer on the SVT Lightning's 5.4L SuperCharged engine weighs less than 1/2 of the GT500s. The GT500's balancer is similar to the Ford GTs, however is totally different from the SVT Lightning. Unlike the GT500, the SVT Lightning uses a stand alone pulley bracket support system, which threads into the damper itself.

>Should the GT500 crankshaft allegations prove to be true and the launch of the GT500 is delayed, it could have a potentially devastating affect, not only on the GT500, but it could throw off the timing of other SVT products like the 2008 GT500. Moreover, consumers' feathers are already ruffled over the GT500 due to a variety of issues. Even though order banks opened weeks ago, Ford has failed to provide exterior color examples. They have also failed to provide consumers with absolute horsepower/torque ratings, MSRP pricing and keep in good communication with their PowerLease customers.
