Nuke Performance Deatschwerks VB40a Voltage Booster
Deatschwerks VB40aX1 Single Fuel Pump 40 Amp Voltage Booster.
The DeatschWerks VB40a brings fuel pump voltage boosting to an entirely new level. The industry's first pump booster with digital programming, password protection, and a special brushless pump mode allows voltage output of up to 26 volts.
- Single / Dual fuel pump booster (X1 / X2)
- Standard mode up to 20 volts
- Brushless mode up to 26 volts
- Programming via roller wheel and digital screen
- OLED Screen
-
User-defined passcode protection
The VB40a is universally compatible with all makes and models and is available in both single-pump (VB40aX1) and dual-pump (VB40aX2) versions. The Deatschwerks VB40a voltage booster is limited to 40amps. Increased flow results will stop when the total pump(s) amperage hits 40amps.
