NXS Billet Aluminum
Racing Converters

5 Axis CNC Machined Body & Fins

Starting At $5600

The NXS Full Billet Racing Converter is the result of over 30 months of converter research and development which has yielded the most significant gains for blower cars in recent history. The NXS features the best of both worlds, it is looser at the hit and tighter after the engine speed comes up. This puts the power to the ground at the launch smoother than any converter or clutch ever has before, and still drive the tire harder at the top of each gear.

This is the converter that has been laying down 60′ times in the .80’s for not one, but multiple PDRA Pro Extreme class cars and holds ALL of the current doorslammer records for supercharged cars. If your car has a Roots or Screw, it’ll likely be faster with the NSX Billet Aluminum Converter. We’ve also have record setting versions out for X275 class cars with Blower and Nitrous Combinations.

What sets the NXS apart from other converter designs is the first of it’s kind split-blade pump impeller. That means there are 35% fewer blades on the low pressure side and 35% more blades on the high pressure side. This gives you more slippage down low to get engine speed up, which makes the motor happy then it brings the driveshaft RPM to the engine RPM downtrack.


  • 5 Axis CNC Machined Body and with unique fin arrangement
  • NCRC Extreme Duty Monster Mechanical Diode

  • Custom 5 Axis CNC Machined Fins increase efficiency.

  • Optional CNC Machined Billet Titanium Options

The full billet design of the NXS converter has many benefits, for starters it’s approximately 12 to 20 lbs lighter than other bolt together converters, and it’s 6 lbs lighter than our aluminum/steel bolt together models. That’s a LOT of rotating weight, and it’s right where it matters hanging off the end of the crankshaft! It also features fully CNC machined fins for outstanding repeatability and consistent fin profiles.

NXS Heavy Hitters

The NXS is a major change in power management for blower cars, in every situation where we’ve had a customer switch to it, they have picked up immediately, with sometimes dramatic ET improvements without major changes. On cars of this caliber, it’s not often you can bolt something in and make a big improvement, but with the NXS many have found it to reward them with impressive results.
