Kong Supercharger X-Port Package
The stock supercharger on the Camaro ZL1 delivers strong performance out of the box — but for enthusiasts chasing more power, quicker response, and more top end power, the factory LT4 unit eventually becomes a bottleneck. That’s where porting comes in. The Kong Supercharger X-Port Package reworks the internal airflow of your OEM blower to help your setup breathe better and make more power — all while keeping the look and fit of the stock unit. It's not about pushing the blower harder; it's about helping it work smarter.
What Is The Kong Supercharger X-Port Package?
The Kong Supercharger X-Port Package is a precision CNC porting service designed to extract maximum performance from your factory LT4 supercharger. Specifically developed for platforms like the Camaro ZL1, this upgrade reworks the internal geometry of the blower, allowing significantly improved airflow, reduced turbulence, and more efficient boost delivery — without compromising reliability.
At its core, the X-Port isn’t just a port job; it’s a data-driven performance solution built around flow bench testing, real-world dyno tuning, and extensive racing feedback. Whether you're running a bolt-on build or preparing for a high-horsepower setup, this upgrade transforms your OEM supercharger into a true performer — capable of supporting well over 1,000 horsepower when paired with the right components.
We take KONG’s proven performance and bundle it with the necessary upper pulley options, biller lid and larger 103mm TB in our STAGE.2 package in order to provide a one click solution and maximum cost savings!
Why Upgrade Your Camaro ZL1 With The Kong X-Port Supercharger?
If you’re building serious power on your Camaro ZL1, you’ll quickly hit the limits of the stock LT4 blower. That’s where the Kong X-Port Supercharger upgrade steps in — not as an over-the-top replacement, but as a precision-engineered refinement of the supercharger you already have.
One of the biggest reasons to go with the Kong Supercharger X-Port Package is efficiency. The ported design minimizes restrictions in the air path, which reduces heat buildup and parasitic loss — two major issues when you start pushing boost levels. The result? Cooler intake temps, better throttle response, and more horsepower.
For ZL1 owners aiming for that next performance tier, this upgrade works amazing with our Katech 103mm TB, more aggressive cam profiles, and higher boost targets. It's an ideal match for anyone who’s already invested in core camaro zl1 aftermarket parts like headers, fuel system upgrades, or pulley changes.
The best part is, you keep your factory look — but under the hood, it’s a whole different machine.
Inside The Kong X-Port Process: What Makes It Different?
The Kong Supercharger X-Port Package isn’t just about cutting material from the blower — it’s a refined engineering process developed through precise testing and calibration. Each LT4 supercharger sent to Kong goes through a highly specialized porting procedure that maximizes both airflow and performance reliability, specifically for high-output applications like the Camaro ZL1.
CNC Porting With Flow Bench Validation
The porting is done entirely via CNC — not by hand — which means every cut is consistent, accurate, and repeatable. More importantly, every revision of the X-Port design has been validated using flow bench data to ensure real-world improvements, not just theoretical gains.
Attention To Rotor-To-Casing Clearance
Maintaining ideal rotor clearances is critical to blower efficiency. Kong Performance doesn’t just open up the ports — they preserve the critical tolerances that allow the blower to maintain peak boost pressure without unwanted bleed or loss of efficiency.
Designed Specifically For LT4 Geometry
The X-Port design is tailored for the unique inlet and rotor geometry of the LT4 supercharger, as found on the ZL1. This isn't a universal port job — it’s a custom approach to getting the most from the specific blower used in GM’s factory supercharged V8s.
Results You Can Feel On The Street Or Strip
After installation and proper tuning, ZL1 owners report significantly better throttle response, midrange pull, and top-end power. Whether you’re chasing numbers or just want your car to pull harder through every gear, the difference with a kong ported blower is instantly noticeable.
Supporting Mods To Maximize The Kong Ported Blower On A ZL1
Upgrading to the Kong Supercharger X-Port Package unleashes serious airflow potential — but to fully take advantage of that performance, your Camaro ZL1 build needs the right supporting modifications. This is where thoughtful pairing makes all the difference between modest gains and truly transformative results.
Throttle Body And Intake Upgrades
Ported blowers benefit immediately from a larger throttle body. Consider pairing your Kong X-Port with a 103mm throttle body to remove restrictions at the front of the system. A high-flow intake also complements the added airflow capacity, helping the engine breathe more freely at higher RPMs.
Pulley Combinations And Belt Alignment
To build boost efficiently, the right pulley setup is essential. A smaller upper pulley or larger lower pulley increases blower speed, taking full advantage of the smoother, higher-flow design of the kong x-port supercharger. Just make sure your belt alignment and tension are adjusted to handle the new configuration. For cars making 750rwhp and up, we always recommend a proper 10-rib belt system with LT5 tensioner to keep all that torque to the tires where it belongs.
Fueling And Cooling
More air means more fuel — and more heat. Upgrading your high-pressure fuel pump and injectors is not only easy when the blower is off the car being ported, but it ensures your are able to feed that hungry LT4 under load for maximum power outputs. Equally important is keeping intake temps under control, and that’s where ZL1 cooling mods come in. Better cooling supports consistency, especially during long pulls or hot weather. That is why most of our Stage.2 Kong XPORT clients also package along with our Stage.2 Supercharger Cooling package at the same time.
Monitoring What Matters
High-performance builds require accurate data. We always recommend integrating ZL1 gauge to monitor critical parameters like boost, IATs, AFR, and fuel pressure. These tools keep you informed — and your engine protected. That is why most of our Stage.2 Kong XPORT clients also package along with our Banks iDash + AEM wideband gauge package at the same time.

Is The Kong Supercharger Upgrade Right For Your Build?
Not every ZL1 needs a ported blower, and a ported blower may not be enough for your high HP build. But if you’re pushing beyond bolt-ons and aiming for 700-900rwhp, then a factory ported Kong Supercharger X-Port Package is a proven way to elevate your setup without replacing the entire supercharger. The key is understanding where you are in your build journey, and where you want to go next.
You Want To Keep The Factory Blower
Swapping to an aftermarket blower is a big investment — not just in parts, but in supporting changes. With the kong performance package, you get many of the same benefits while retaining stock fitment, aesthetics, and serviceability.
You Plan To Grow The Build Over Time
Whether you’re planning to add a cam, meth injection, or build the bottom end down the road, a kong ported blower gives you the airflow you’ll need — and lets you scale power as your build evolves up to about 900rwhp. Although many cars have seen 1,000rwhp and above with the stock ported blower, we typically recommend going to a 2650 if your goals are 950-1,000rwhp or more.
You're Focused On Performance You Can Use
This isn't just about dyno numbers. The X-Port blower improves throttle response, midrange torque, and high-RPM power — right where you feel it on the street or at the strip.
Real-World Performance: What ZL1 Owners Can Expect With A Kong Ported Blower
Upgrading to the Kong Supercharger X-Port Package isn’t just about dyno sheets. It transforms how your ZL1 behaves in real-world driving conditions. Here’s what owners typically notice after the upgrade:
Noticeably Stronger top end pull - The increased airflow efficiency kicks in right where the little 1.7L needs it most, after 5k rpm, right where the OEM blower starts to run out of steam. On the street, this results in the car feeling faster everywhere. The 1.7L blower already makes gobs of torque, which can make launching the car or rolling stabs tricky to gain traction. Although our XPORT did not reduce torque, it did move our peak torque up approx 1,000rpm which makes the car easier to launch.
Higher Peak Horsepower Without Raising Boost Levels - Thanks to the ported geometry, the blower can move more air at the same pressure, which reduces heat and parasitic drag. Many setups gain 40 to 60+ RWHP without spinning the blower faster or placing additional stress on the engine.
Improved Tuning Characteristics - With smoother and more consistent airflow across the RPM range, your tuner has a more stable platform to work with. This allows for tighter control of timing, fuel delivery, and torque management, resulting in better drivability and overall performance.
Better Throttle Response And Part-Throttle Performance - The blower responds more quickly to input and delivers power with greater precision. The car feels sharper and more responsive, even during regular daily driving.
Maintains Street-Friendly Behavior - Despite the added performance, the ZL1 keeps its stock-like idle, cruising ability, and low-speed manners. It’s a performance upgrade that doesn’t force you to sacrifice comfort or daily usability.
