Why Hellcat Owners Come to FAS
The Hellcat platform has been FCA's performance flagship for over a decade — Charger, Challenger, Durango, and everything in between. The 2.4L twin-screw supercharger is one of the most capable factory blowers ever put in a production car. It's also one of the most modified. Whether you're shopping for a ported unit or a complete hellcat supercharger for sale, FAS has seen every failure mode, every limit, and every path through it.
The factory snout is the weak link on 707 builds. The factory bearings weren't spec'd for sustained high-boost use. Redeye owners pushing beyond 800 whp run into the same inlet restriction that limits every twin-screw at elevated output. FAS solves all three — billet snout replacement, bearing upgrades, and precision porting — as standalone services or as a complete platform package.

2.4L Billet Supercharger Snout
from $1,899.99The factory cast snout is the first thing to go on a serious Hellcat build. FAS machines a billet replacement that eliminates the flex and bearing wear the stock casting allows under high-boost conditions. Direct bolt-on. No adapter required.
Shop Billet Snout →Snout Bearing Upgrade
from $199.99Factory bearings in the Hellcat snout are rated for stock boost. Push past that and you're borrowing time. FAS replaces them with upgraded spec bearings as a standalone service or included in any full build package.
Shop Bearing Upgrade →Dominator 2.4L Supercharger Package
from $2,175Race porting performed on your own 2.4L IHI core — a ship-in service, not a replacement blower. Base package covers the 108mm ported and polished snout, ported bearing plate with billet air foil, upgraded bearings, pin bushings and new oil. RACE ELITE and the 130mm billet snout are paid upgrades.
Shop Dominator 2.4L →Dominator 2.7L Supercharger Package
from $2,175The same race porting work spec'd for the larger 2.7L IHI in Redeye, Demon and Super Stock builds. Your 2.7L core is required. Pulleys and calibration are not included, and core purchases are non-refundable.
Shop Dominator 2.7L →Supercharger Porting
from $699Inlet and outlet porting on the factory 2.4L or 2.7L for owners who want more from the stock blower without a full swap. Improves airflow efficiency across the RPM band, reduces inlet temps, extends the power curve.
View Porting Service →Predator Lower Pulley
from $899.99The FAS Predator lower pulley is a no-tune-required slip-on upgrade designed for improved belt traction and longevity. Billet, hard-anodized, available in 8-rib and 10-rib configurations. Compatible with standard Hellcat 2.4L builds.
Shop Predator Pulley →Hellcat vs. Redeye: What's Different
The standard Hellcat (707 hp) runs the 2.4L IHI-sourced twin-screw at 11.6 psi. The Redeye (797 hp) runs the same basic architecture but with a ported throttle body, a different bypass valve, and higher factory boost — closer to 14.5 psi.
Important — parts differ by trim
The snout design is different between the two. The Redeye snout is not interchangeable with the standard Hellcat unit. FAS stocks billet snout options for both. Specify your exact trim — Hellcat, Redeye, Super Stock, or Jailbreak — at checkout or when booking.
For porting work, both units respond well. Redeye builds typically have less headroom on the stock blower (it's already closer to its limit from the factory), so Dominator packages are more common on Redeye builds targeting 900+ whp.
| Spec | Hellcat 707 | Redeye 797 | FAS Dominator |
|---|---|---|---|
| Factory boost | 11.6 psi | 14.5 psi | Calibrated to build |
| Snout design | Standard | Redeye-specific | 108mm ported and polished (your own snout) |
| Snout interchangeable | — | No | — |
| Max whp (ported stock) | 850 | 820 | Specified to support 1,100+ whp with the correct supporting build (paid RACE ELITE upgrade) |
| Package gain over stock | — | — | 75–135+ whp |
| Billet snout | Sold separately | Sold separately | Paid upgrade — not in the base package |
Technical Detail
The 6.2L Hellcat HEMI is a strong foundation. The rotating assembly is robust, the cylinder heads flow well, and there's real headroom in the block. The supercharger is where most builds hit their ceiling.
The 2.4L twin-screw design is a positive-displacement blower — linear boost curve, low heat at moderate output, excellent response. The problem is the factory inlet port and bypass valve geometry, which restrict airflow above 850 whp and cause inlet temperature rise that pulls timing.
The snout bearing failure mode is separate: the stock bearings tolerate sustained high-boost poorly, and bearing wear shows up as noise, then vibration, then catastrophic failure if ignored.
FAS addresses these in order: bearings first on any build where we're increasing boost, snout replacement on builds where stock casting geometry is limiting output, full precision porting for owners pushing the stock blower to its limit before upgrading. Every build gets a documented spec sheet.
Frequently Asked Questions
What hellcat supercharger upgrades does FAS offer?
FAS offers the full spectrum of Hellcat IHI supercharger upgrades: precision snout porting (2.4L and 2.7L), the FAS Dominator 2.4L and 2.7L ported supercharger packages, billet snout replacements, upgraded snout bearings, and the Predator lower pulley kit. Every service is performed in-house at our Punta Gorda, FL shop. Parts ship nationwide.
How much does a hellcat supercharger upgrade cost?
Starting prices: Snout Porting from $699 · Billet Snout from $1,899 · Dominator 2.4L Package from $2,175 · Predator Pulley Kit available separately. Full installed build packages start higher depending on supporting mods. Contact FAS at (941) 740-1699 for a build-specific quote.
What whp can I make on a ported hellcat supercharger?
A properly ported stock 2.4L on a dialed tune typically supports 800–850 whp on a Hellcat. The Redeye has less headroom on the stock blower because it is already factory-boosted higher, so DOMINATOR packages are common on Redeye builds. The DOMINATOR product record supports a 75–135+ whp gain over stock on the same supporting setup; the paid RACE ELITE upgrade is specified to support 1,100+ whp with the correct supporting build. Final vehicle output depends on pulleys, fuel and calibration, which the package does not include.
Do I need a tune for the Predator Pulley?
The FAS Predator lower pulley is designed as a no-tune-required drop-in on stock-calibration vehicles. It improves belt traction and longevity without requiring an ECU calibration change. If combined with additional mods (throttle body, port work, injectors), a calibration update is recommended.
Can I ship my hellcat supercharger to FAS?
Yes. FAS accepts core-out supercharger assemblies for rebuild, porting, and snout replacement nationwide. Remove the blower from your vehicle, pack it securely, and ship it to our Punta Gorda, FL shop. We rebuild, port, or replace the snout and ship it back.
How long does hellcat supercharger porting take?
Snout-porting lead time varies with current shop workload and part condition. Full DOMINATOR package builds may take longer depending on parts availability and build complexity. Contact FAS for the current lead time before shipping your part.
Does FAS service Redeye, Demon, and Trackhawk superchargers?
Yes. FAS services all IHI-platform superchargers: the 2.4L in the standard Hellcat, Durango SRT, RAM 1500 TRX, and Jeep Trackhawk — and the 2.7L in the Redeye, Super Stock, Demon, and Demon 170. Note that snout parts differ by displacement; specify your exact trim when ordering.
What is the Dominator package vs. snout porting?
Both are performed on the supercharger you already own. Snout porting reworks the inlet section only. The DOMINATOR package is the fuller race porting job on the same core: a 108mm ported and polished snout, a ported bearing plate with billet air foil, upgraded snout and bearing-plate bearings, new pin bushings and new oil. It is a ship-in service — you send the blower in and FAS returns it built. The billet snout, the RACE ELITE specification, pulleys and calibration are priced separately.
