If you are looking to maximize the airflow through your LT4 supercharger, Kong Performance has you covered. Our supercharger port designs are based on years of hand porting experience. All of our latest ports were designed, created, tested, and programmed on our 5 axis CNC in house using highly advanced porting software! 40-80rwhp proven gains!!! (+40-60rwhp additional with “Stage X” Upgrade)
NEW “Stage X” Port Upgrade
- Our new “Stage X” LT4 Port Upgrade is available now! This is an add on to our already outstanding CNC Supercharger porting service for the LT4. The “Stage X” is designed for those who are looking to get as much power as they can from the factory supercharger. In addition to our normal CNC porting, the “Stage X” includes additional CNC machining that has been flow simulated, chassis dyno tested, and track proven. On capable engines with supporting mods and fuel, the Kong “Stage X” LT4 can make upwards of 1000rwhp. The days of needing to jump straight to a bigger supercharger on this platform are a thing of the past. The “Stage X” turns the stock 1.7L LT4 into a BEAST!
FAST TURN AROUND! We typically operate at a 3-5 business day turn around time on porting so we can get your supercharger back to you as quickly as possible!
The process is simple!
- Once you checkout, print out your emailed receipt and put that in a box with your supercharger. Make sure the supercharger is padded well on all sides. (Do not use packing peanuts)
- Be sure to remove all sensors and gaskets please!
- We prefer UPS, Fedex, or DHL for shipping to us.
