2.95" serp side jackshaft, 3.2" SC side on
JS, 3.0" on SC
I should clarify on that 687whp number on the V3-Si. Z1 is the only one who displayed a number like that. Is this daily driven? Did it leave the dyno at that power? Was it straight 93? Im not sure.
I know that Dynosty holds the record for the ACE kit but of course that took E85 and they made 685whp.
