Trying to figure a few guys out on here.I have purchased from most major vendors,Spent several thousand with Jack among others and have had no problems as of yet.This discussion got me thinking so I asked my engine builder about my intercooler(The Jack)with a new stage motor I dont want any problems.He laughed and said dont believe everything you read.So I dont.I just hope you dont ruin a guys business for what seems like a witch hunt.
