Hellcat Supercharger
Upgrades
Built and installed at FAS Motorsports — ported supercharger packages, pulley kits, and full-system power builds for Dodge Challenger & Charger SRT Hellcat 6.2L.
Why Upgrade the Hellcat Supercharger?
The factory 2.4L IHI supercharger is a solid piece of engineering, but it leaves significant power on the table. The rotor pack, inlet, and throttle body are all restricting flow well before the engine runs out of capability. On a 717 hp Hellcat, a properly ported supercharger with a pulley change and matching throttle body can push output to 800–900+ WHP on pump gas — without touching the bottom end.
FAS Motorsports has built Hellcats at every power level from bolt-on street builds to full E85 1,000 WHP race builds. Every package is verified on our in-house AWD dyno in Punta Gorda, FL before the car leaves the shop.

Signature Package
The FAS Dominator Supercharger Package
The FAS Dominator is our in-house hellcat supercharger upgrade package — built around a race-ported supercharger rotor pack with a port-matched inlet, paired with our billet snout, aggressive pulley combination, and a full custom dyno tune on the AWD dyno in our Punta Gorda shop.
- ▸ Race-ported supercharger rotor pack with port-matched inlet
- ▸ FAS billet snout & lower pulley kit
- ▸ 108mm throttle body (removes factory restriction)
- ▸ Pulley package calibrated for target power level
- ▸ Full custom AWD dyno tune — pump gas + E85 maps
- ▸ Professional installation — Punta Gorda, FL
What makes it different
Unlike bolt-on kits from Whipple or Magnuson that replace the supercharger entirely, the FAS Dominator upgrades and ports the factory unit. This retains OEM reliability while dramatically improving airflow — and costs significantly less than a full supercharger replacement at comparable power levels.
Also available
- ▸ Whipple Gen 5/6 installation (3.0L, 3.8L)
- ▸ Magnuson TVS2650 installation
- ▸ Hybrid builds — FAS billet + aftermarket supercharger
- ▸ 2.7L Dominator package for max ported output
Platforms We Build
Hellcat Supercharger — Common Questions
What supercharger does the Hellcat have from the factory? ▾
The factory Hellcat uses a 2.4L IHI twin-screw supercharger producing 6–7 psi of boost, rated at 717 hp on the standard Hellcat and 797 hp on the Redeye. The supercharger is mounted on top of the 6.2L HEMI V8 and is an integral part of the engine assembly.
What is the best Hellcat supercharger upgrade? ▾
The most popular upgrade path is a ported or replaced supercharger combined with a pulley change, 108mm throttle body, and supporting fuel system work. FAS Motorsports offers the FAS Dominator package — an in-house ported supercharger rotor pack with port-matched inlet, upgraded throttle body, and custom dyno tuning, built specifically for the Hellcat 6.2L platform.
How much power can a Hellcat supercharger upgrade make? ▾
On a stock bottom end with porting, pulley work, and an E85 tune, a Hellcat can reliably make 800–950 WHP. With a full fuel system upgrade and supporting mods, 1,000+ WHP is achievable. FAS Motorsports documents power numbers on an in-house AWD dyno for every package build.
Will a Hellcat supercharger fit a 5.7 HEMI? ▾
Not directly — the factory Hellcat 2.4L supercharger is designed for the 6.2L HEMI and requires the matching intake manifold, fuel system, and engine management system. Fitting it to a 5.7L requires significant fabrication and ECM work. FAS Motorsports can discuss swap feasibility on a per-project basis.
How much does a Hellcat supercharger upgrade cost? ▾
A bolt-on supercharger upgrade with pulley, throttle body, and tune starts around $3,500–$6,000 installed. Full-system builds targeting 900–1,000+ WHP range from $10,000–$18,000 depending on parts and labor. Contact FAS Motorsports at (812) 200-9012 for a build-specific quote.
Does FAS Motorsports install Whipple or Magnuson superchargers on Hellcats? ▾
Yes — in addition to our proprietary Dominator ported supercharger package, we can source and install aftermarket supercharger kits including Whipple Gen 5/6 and Magnuson TVS units. We also offer hybrid builds that combine aftermarket superchargers with FAS billet components and custom tuning.
