Its the extra torque i want, its amazing what 2psi can do.... Fr8 where does the 7psi pully start to build boost in the rev range!??!??
P.s the vortech unit ess use is imo simply fabulous.....far better than the hks units aa use which need expensive unit changes for increased power. V3si can flow 775bhp @ 25psi!! Really a nice unit!
