Supercharger installation rules from TorqStorm

By Alfie Bilk:

Basic forced-induction guidelines (6-10psi boost range) for carbureted systems

  1. Forged pistons preferred for all boosted applications
  2. Cast or Hypereutectic pistons may be used below 500hp and low boost applications
  3. Compression ratios of 9:1 to 9:5.1 ideal for boost levels of 6-8 psi on 91-93 octane pump gas
  4. Lobe separation of 112 to 116 degrees, split pattern works best
  5. Fuel pump requirements for carbureted systems must be capable of supplying proper amount of fuel at maximum operating pressure. To obtain maximum fuel pressure required under boost, add idle fuel pressure to maximum boost pressure. (If your idle setting is 8psi and your maximum boost is 8psi your maximum fuel pressure required is 16psi)
  6. Use a blow-through carburetor. TorqStorm offers Holley Mighty Demon carburetors specifically prepared by the factory for blow-through purposes. Available in the following cfm ratings:

650 CFM Part number 5282020BT
750 CFM Part number 5402020BT
850 CFM Part number 5563020BT

  1. Must use carbureted boost-reference fuel pressure regulator with a 1:1 rise ratio
  2. Headers recommended for maximum performance
  3. Will work with single or dual-plane intake manifolds, (more torque generated by dual-plane design)
  4. Ignition control recommended with adjustable boost-timing retard to prevent detonation. (MSD BTM part number 6462)
