What Porting Does — And What It Doesn't
Porting removes casting flash, opens inlet and outlet ports, and smooths the airflow path through the supercharger housing. Less restriction means more air moves per revolution without adding boost pressure or heat.
On a 2.4L Hellcat TVS, the biggest restriction is almost always the inlet — stock castings leave material in the airflow path that serves no structural purpose. On the 2.7L IHI, the discharge side is where most of the gain lives.
What it doesn't do: fix a worn blower, compensate for a bad tune, or replace proper pulley sizing. If your blower is making bearing noise or losing boost, port it after a rebuild — not before.
Reduces inlet restriction
Stock castings leave material with no structural purpose
Smooths airflow through the housing
Less turbulence = more consistent boost delivery
Improves discharge efficiency
Critical on IHI twin-screw platforms (2.7L Demon)
Hand finished and flow-bench verified
Every unit tested before ship-back — no guessing
Does not fix mechanical wear
Rebuild first if the blower has bearing noise or pressure loss
Platform-Specific Work
Porting by Platform
2.4L Hellcat TVS
Charger / Challenger / Trackhawk / Durango Hellcat
The most-ported Hellcat platform in the shop. On built motors running E85 or race fuel, inlet restriction is often the ceiling before you start spending money on bigger hardware.
- ▸Precision inlet port opening and blending
- ▸Rotor housing smoothing
- ▸Snout outlet porting
- ▸Hand finished
- ▸Flow-bench tested before ship-back
Best for: Hellcat builds targeting 700+ rwhp where the blower is the restriction. On pump gas below 700, tune first.
Shop Dominator 2.4L Package →2.7L IHI Twin-Screw
Dodge Demon / Demon 170 / Hellcat Redeye High-Output
The IHI responds to inlet and discharge porting differently than the TVS — the discharge side is where most of the gain lives on this platform. FAS has rebuilt and ported all three generations of this blower.
- ▸Inlet port cleanup and opening
- ▸Discharge channel blending
- ▸Hand finished
- ▸Flow verification post-porting
Rebuilding too? Ask about combining porting with the rebuild — blower is already apart.
LT4 Supercharger
C7 Z06 / Camaro ZL1 / CTS-V / CT5-V Blackwing
LT4 snout porting is a documented mod for Z06 and ZL1 builds chasing 700+ rwhp on the factory blower. FAS applies the same precision approach to the Eaton TVS R1740 that it applies to every platform.
- ▸Snout porting (inlet side)
- ▸Port blending and smoothing
- ▸Hand finished
- ▸Flow verification
Typical gain: 15–30 whp on a well-supported build with more consistent boost curve and lower inlet temps.

How to Ship Your Supercharger to FAS
- 01
Call or email before you ship
Confirm platform, get current lead time, and we'll tell you exactly what to pull. (812) 200-9012 · sales@fasmotorsports.com
- 02
Pull the right parts
Snout porting only? Send the snout. Full inlet and discharge porting? Send the complete blower with rotors.
- 03
Pack it right
Wrap the snout and all port openings. Use original packaging if you have it. Ship to: FAS Motorsports · 6161 Riverside Dr · Punta Gorda, FL 33982.
- 04
We precision port and hand finish it
Every unit is precision ported, hand finished to specification, and flow-bench verified before crating. No shortcuts.
- 05
Back in 3–5 business days
Ready to bolt back on and tune. We'll confirm ship-back date when you book.
Before You Ship — Read This
If your blower has bearing noise, pressure loss, or any mechanical symptoms — call us first. Porting a blower that needs a rebuild doesn't fix the problem. The right sequence is rebuild first, then port.
FAS does both. If you're already pulling the blower for a rebuild, porting is the logical add-on — we're already in there.
IHI Rebuild Service →Why FAS — Not a Generic Machine Shop
Generic machine shops cut metal. FAS ports superchargers — specifically — and validates the result. Three generations of builders, every part worked and verified under one roof since 2002.
Supercharger Porting — Common Questions
Do I send the whole blower or just the snout?▾
Snout porting only? Send the snout. Full inlet and discharge porting? Send the complete blower with rotors. Call before shipping and we'll tell you exactly what to pull for your specific build.
What kind of gains can I expect on a Hellcat?▾
Depends on supporting mods, fuel, and tune. On built motors running E85 where the inlet restriction is the limiter, porting removes that ceiling. On a stock Hellcat below 700 rwhp, spend the money on a tune first — porting's gains stack on top of a proper foundation, not underneath one. Call the shop for a straight answer on your specific setup.
Will this void my factory warranty?▾
Yes. Any internal modification voids OEM warranty. This is for builds, not stock vehicles.
My blower already has some porting from a previous shop — can FAS rework it?▾
Send photos first to sales@fasmotorsports.com. If there is material left to work with, yes. We've corrected rough or oversized previous porting work before — it's case-by-case.
Do you port LSA, LS9, M122, or Audi Eaton blowers?▾
Yes — all of them. The service page above covers Hellcat, IHI, and LT4. Call or email for LSA, LS9, M122, and Eaton platforms. Same process: ship-in, precision ported and hand finished, flow-bench verified, back in 3–5 business days.
How is hellcat supercharger porting different from a full replacement?▾
Porting improves the factory unit — it does not replace it. You keep the factory ECU integration, factory fitment, and proven reliability, while opening the airflow path for better output. A full swap (Whipple, Magnuson) costs significantly more and changes the platform architecture. Porting is the upgrade for builds that want the most from the IHI before making that decision.
