Bell Engineering / Cartech Adjustable boost dependent fuel pressure regulator. This Original is the FOURTH generation design in the 25 years they’ve built these regulators. It is, by far, THE BEST.
PURPOSE OF THE RISING RATE FUEL REGULATOR (FMU)
The B.E.G.I. regulators (formerly known as the Cartech Regualtor) are designed specifically to add fuel to EFI engines modified with turbos, superchargers, and normally aspirated. This is accomplished by using the manifold vac/pressure to drive the fuel pressure up as the boost rises, or with the N/A engines, as the vacuum goes toward atmospheric.
If they already build the best FPR’s (often called FMU’s), what’s the sanity of making another? The answer is to keep the copy’ers way behind. Their original FMU, introduced in 1975, has been copied six times and still used by four companies. The copies still have yet proven to work properly. The 2020 series regulator, introduced to you here, is the fourth generation design to come from B.E.G.I., and every new design has been better than the previous. Imagine how vastly better these new designs are than that 25 year old relic the other guys are still producing and using!
WHY IS IT BETTER?
Billet manufacture, improved valving, and fewer parts with the integrated accessory design. Further, they’ve increased the span of adjustment for broader rates of gain. Rates now go from 1.1:1 up to almost 10:1. Even the onset of gain is adjustable! No other regulator on the markert has the onset adjustment.
