A.T.I Prochargers twisting crank nose's off?
Has anyone seen a A.T.I procharger snap the nose off a crank?? I was only running eight pounds of boost the first time and 12lbs the second. Ati says they have never seen this (yea right). My machine shop says the cranks i was using are strong enough just they were defestive and replaced the second one. Please help
