Then there are those with 28k miles on the setup with no problems as well.
The cog belt shouldnt put anymore stress on the crank and blower than the serp belt... What's the resoning behind that statement?
the serpentine belt does allow for slippage when the stresses become too great, the cog setup doesnt; so those stresses are transmitted into the next available piece of the puzzle, be it the crank or the blower snout.
its just like people snapping axles with DR's and those not snapping axles with slicks; the shock of the launch is soaked up with the slick itself wrapping; as opposed to the DR which transmits all that shock to the next available part, which would be the axle/shaft.
$1200? Yikes
are you running the cod setup tractionless?
