Anyone know if the Lightning Whipples use the same pulleys as the Whipple Cobras?
Specifically I found a 4" upper pulley from a 2.9L Whipple Lightning and I am looking for a 4" for my 03 Cobra 3.4L
Bumping an old thread. Anyone know what o ring size is for this kit? Ive tried the factory one off my stock cross over and ordered a set of new ones for the factory cross over tube. Both of them tore going in.
