Tech Tips:
- Supports up to 1200 EFI or 1450 Carb HP (@ 60 PSI at 13.5 Volts / 17 AMP Draw). Many variables will affect the end performance. Estimates are based on gasoline. Individual systems will vary based on fuel system design, regulator type, fuel cell location, etc.
- Both EFI and carbureted systems will need a bypass design regulator. We recommend the HL12879 or FPR15 Bypass Regulators for these installations. They can be used for both carbureted and EFI systems.
