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.  Read condensed details below.

 

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 6-8psi on 91-93 octane pump fuel

4. Use lobe separation angle 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 custom billet blow-through carburetors sized per application. Contact TorqStorm direct for carburetor specs and pricing.

7. Must use carbureted boost-reference fuel pressure regulator with a 1:1 rise ratio

8. Headers recommended for maximum performance

9. Will work with single or dual-plane intake manifolds (more torque generated by dual-plane designs)

10. Ignition control recommended with adjustable boost-timing retard to prevent detonation. (MSD BTM part number 6462)
