The Unblown kits are designed to mount to the balancer. Includes 5/8" shaft mandrel, pump bracket, two drive pulleys, drive belt and mounting hardware.
Enderle's Blown Belt Drive kits feature a beefier 1.00" shaft drive on a billet aluminum mandrel. Does not include engine bracket due to the fact that most blower cars require a custom fabricated bracket. Belt drive components are available separately.
