My engine rebuild starts soon . Arias pistons,Pauter rods,Nismo cams,heavy duty springs`, I would like to know how much boost can be safely ran [ with a Vortech SC ] on 92 octane ? And how much timing retard is needed ? I think with my smallest pulley [2.87 serp pulley ] I can make 11 to 12lb's of boost at 7,000rpm .
