The BoostWorx fuel module control system has everything needed to provide a stand alone, manifold referenced, OE-type returnless fuel system for all generations of the Ford Control Pack for Coyote engines.
When used with the low-cost GM, Ford, and many other OEM returnless PWM controlled fuel modules, the system will provide any base pressure with a 1:1 manifold referenced fuel pressure change for up to 25psi of boost. It will act just like a mechanical fuel pressure regulator would with the ECM tuned in the same manner. The fuel injector does not know if the fuel supplied is pumped by a return or returnless system.
The key to making this system simple to use is the stand-alone manifold pressure sensor that tells the BoostWorx controller how to adjust the fuel pressure.
Just like a manifold referenced mechanical fuel pressure regulator, simply connect the hose from the pressure sensor mount to the intake manifold, set the fuel pressure according to the need, and you’re done. Base fuel pressures at idle are typically between 42-60psi, but the VaporWorx controller has much greater range if needed.
The as-delivered fuel pressure will be approximately 43psi at idle, but turning the pressure adjustment screw two turns CW will rough set a 60psi pressure.
The BoostWorx controller can also be used with any engine that needs to have a separate MAP sensor for manifold referenced fuel pressure. The system as normally supplied will work with the GM truck and car, CTS-V2, Gen5/6 Camaro, and Ford fuel pump modules used in chassis that have a factory Fuel Pump Driver Module/FPDM.
The fuel requirements for all versions of the Ford Controls Pack for the Coyote crate engine can be met with the BoostWorx controller. When combined with the Gen5 Camaro ZL1 fuel module, a 750hp naturally aspirated / 650hp supercharged fuel pumping system is easily obtained.
This setup has been used in hundreds of retro-swaps with good success.
This kit can also be used in constant pressure mode. Just remove the vacuum line or MAP sensor wiring, and the controller will provide a constant pressure. The controller can also be sent in to VaporWorx to be tuned to a specific MAP sensor.
It is strongly suggested to NOT use an inline filter with with OEM fuel modules except Gen3 Coyote GT500. Final filtering is built in. Some aftermarket fuel filters have a built-in check valve which will cause a heat-soak related overpressure condition that will lock up port type fuel injectors.
The BoostWorx Controller includes these standard features:
- Everything needed electrically to drive the fuel pump module. No relays, external regulators, or return lines needed.
- Unmatched low fuel level capability when used with an OEM style fuel module.
- A minimum 50% reduction in power to the fuel pump during idle and cruise vs traditional systems.
- 40A minimum continuous power rating in a compact controller package. Total size 4”L x 2.1”W x 1-5/8”H.
- Over-temperature shutdown with automatic reset.
- Short circuit protection that will operate indefinitely without damage.
- OEM Delphi/Aptiv connections for terminals, seals, and connector bodies.
- All cross-linked polyethylene wiring.
- UL94 rated components used throughout.
- Integrates into the OE ECM to allow all safety systems to remain functional.
- 10-22v operating capacity. Can be used with voltage boosters. The preferred booster is the JMS FuelMax. Lower than 10v applied to the turn on circuit will cause controller shutdown to protect from an AFR lean condition.
UPDATE! All BoostWorx kits now feature the billet aluminum VaporWorx MAP sensor bracket and 3bar pressure sensor!
