Hellephant Killer Snout: The Ultimate Hellcat Supercharger Upgrade

If you're chasing serious horsepower, airflow matters — and no component is more overlooked than the factory supercharger snout. At SDG Motorsports, we weren’t satisfied with just porting OEM snouts. So we built something better: the Hellephant Killer Snout — a true performance upgrade for IHI 2.4L, 2.7L, and 3.0L superchargers used in Hellcat, Demon, Redeye, Trackhawk, TRX, Super Stock, and even Hellephant platforms.
Why the Stock Hellcat Snout Is Holding You Back
Porting the OEM snout sounds good — until you realize:
Castings vary between years and platforms
CNC porting often leads to dangerously thin walls
108mm claims? They’re false. Most top out between 100–103mm
Welded reinforcements? Those often crack
“I had seven different CNC programs just to keep up with OEM variations,” says Jesse Kloth, founder of SDG. “Eventually I hit a wall — literally. That’s when we decided to design the Hellephant Killer from scratch.”
Built from the Ground Up for Airflow and Strength
The Hellephant Killer Snout isn’t a rework — it’s a reengineering.
True 108mm inlet (machined to 109mm for casting tolerance)
Thicker walls eliminate cracking risk under boost
Material added in key stress zones
OEM fitment maintained for sensors, bolts, brackets
No modifications required for install
It pairs perfectly with the Nick Williams 108mm throttle body, and unlike other "ported" snouts, this one is the real deal — designed for airflow, not just appearance.
Real-World Horsepower Gains
What can you expect when switching from an OEM snout?
Every 1 KPa drop = 5–7 HP when tuned correctly
30–40+ whp gains when paired with a 108mm throttle body
Better throttle response and lower IATs in high-power builds
“It’s not just dyno gains. You can feel it in the seat,” says Jesse. “No more choking the blower with a cast-limited inlet.”
Designed to Handle Boost, Track Abuse, and Street Miles
Many SDG customers are daily driving or racing with our snouts for 50,000+ miles — with zero failures.
No cracks
No bolt-on compatibility issues
No tuning headaches (just re-tune for airflow)
Whether you’re pushing 15 psi or 25+, the structural integrity of the Hellephant Killer Snout stays rock-solid.
Made in the USA with Tight Tolerances and Tight QC
Every SDG snout is manufactured in the USA, held to tolerances within 5 microns, and documented for quality every 10 parts.
“We don’t ship anything we wouldn’t run ourselves. That’s the SDG difference.”
Conclusion: Don’t Port It — Replace It
The SDG Hellephant Killer Snout is the final answer to your supercharger’s airflow problem. It's not a gimmick. It's not a ported OEM compromise. It’s a clean-sheet design, optimized for flow, strength, and reliability.
Upgrade your Hellcat, Redeye, Demon, Trackhawk, TRX, or Hellephant with confidence — and finally unlock the power your IHI supercharger is capable of.
