America has had many a proprietor in the muscle car world, but the Mopar guys have always gone a little above and beyond. There's no mistaking a Dodge Challenger for any other Detroit pony car. Since 1970, they've always been a little bigger, a little louder, and a little crazier than anything else offered. Taking that into account, Holley knows that for Mopar owners, "more" is just enough. That's where we come in.

Wet nitrous systems are the most popular option since they provide the extra fuel to support the added nitous, and don't require any modifications to the fuel injection system (no custom programming of the computer to add fuel when the nitrous is activated). Dry nitrous systems are generally used in racing applications in combination w/ the HP or Dominator ECU w/ custom calibration to add the extra fuel using the fuel injectors (in an EFI application).
