Reply to "Dual Disc clutch"

My biggest problem with a dual-disc clutch in a Pantera is the stock car's marginal clutch disengagement distance, and two discs only make this worse. We NEED an absolute minimum of 0.040" clearance space between the flywheel and the clutch disc, as measured by inserting a feeler gauge thru the ventilation hole in the bellhousing. This amount of course means only 0.020" disengagement clearance between BOTH sides of ONE disc, IF the clutch pedal is matted between shifts. Which no one does.

The math is not hard to extrapolate this amount of space for two discs and both sides of a floater plate. Extra clutch drag means extra ZF synchro wear between shifts and a shorter life for this complicated and increasingly expensive repair.

Since the Byars boys & others had no problem with a single disc in their massive torque BBF & BBC Pantera conversions, and IRS cars of all brands make poor drag racers unless very highly modified, I'm left with doughnut-shoppe-bragging-rights as the main value of dual-disc Pantera clutches.
