Granatelli Motor Sports releases Monster 108mm Throttle body for the Hellcat

 

Granatelli Motor Sports Launches Massive 108mm Throttle Body for Hellcat

Granatelli Motor Sports said 105mm wasn’t big enough—so they took it to the next level. Introducing the all-new Granatelli 108mm Hellcat Throttle Body, engineered for those who demand more airflow, more power, and zero compromises.

This isn’t just an upgrade—it’s a statement. Designed specifically for Dodge Hellcat, Redeye, Demon, and Trackhawk applications, this throttle body sets a new benchmark for performance in high-horsepower HEMI builds.

Why 108mm? The Bigger the Bore, the Bigger the Power

When you’re pushing boost and fuel into your Hellcat at record volumes, your engine needs to breathe—and breathe big. The factory throttle body simply isn’t enough. Even 105mm aftermarket options have their limits. That’s where Granatelli steps in.

  • Massive 108mm Opening: More airflow means more horsepower and torque, especially at wide open throttle.
  • Fully CNC-Machined Housing: Precision cut from billet aluminum for flawless fit and finish.
  • Drive-By-Wire Compatible: Plug-and-play with factory electronics—no tuning required (though tuning will maximize gains).
  • Built for Boost: Perfect for supercharged and turbocharged Hellcat engines running high PSI.

Designed for Real-World Power and Street Dominance

Whether you’re building a 1,000+ HP street monster or dominating at the drag strip, the 108mm throttle body gives you the edge. Tested on high-performance builds under real-world conditions, this throttle body doesn’t just flow—it delivers.

Paired with a cold air intake, ported blower, or upgraded supercharger, the 108mm throttle body becomes the missing piece in your airflow equation. It’s designed to support serious gains and help your HEMI perform the way it was born to.

Installation Made Easy

The Granatelli 108mm Throttle Body is designed to bolt directly onto most Hellcat-based platforms with no cutting, grinding, or fab work. It retains full OEM functionality and throttle response, while delivering upgraded performance right out of the box.

Applications include:

  • Dodge Challenger Hellcat / Redeye
  • Dodge Charger Hellcat / Redeye
  • Dodge Demon
  • Jeep Grand Cherokee Trackhawk
  • Durango SRT Hellcat
