XHD Supercharger Torque Converter

Extra heavy duty full race converter with anti-balloon plates should be used to handle the massive torque produced by Negative Pressure Supercharging

The XHD supercharger converter is a full race converter which uses extra heavy duty parts and anti-balloon plates to handle the massive low rpm torque produced by Negative Pressure Supercharging and prevent the converter from ballooning. We developed the XHD converter in conjunction with Autoflite Engineering in Australia because typical performance converters failed after several months. Therefore, the XHD converter should be used with the Negative Supercharging Kits.



Note: XHD supercharger converter is included with the Impulse Crate Engines as standard equipment.

Typical performance converters will gradually balloon and fail with Negative Pressure Supercharging
If full throttle is used several times each week and the vehicle is not used for towing, standard or typical performance converters should survive for several years before they gradually balloon and fail. However, if full throttle is used excessively each day or the vehicle is regularly used for towing, standard or typical performance converters will gradually balloon and fail after several months from the massive low rpm torque produced by Negative Pressure Supercharging. This will also damage the transmission.

Contents and Features of the XHD Supercharger Converte
  • 2000 rpm flash stall*
  • New hardened and ground pump
  • 4 heavy duty torrington bearings
  • Anti-balloon plates
  • Fully furnace brazed turbine
  • Fully furnace brazed impeller
  • New steel turbine hub
  • New springs and rollers
  • New base fibre
  • 4 x 3/8" UNC grade 5 flex plate bolts
  • Fully pressure tested and balanced

* Flash stall is measured by applying full throttle while the vehicle is traveling at 15mph (25kmh) in 3rd gear and holding the brakes until the torque converter stalls at the rpm the rear wheels begin to spin or the vehicle increases in speed.
