Corvette LS9 Power Package for C6 ZR1
You may think it would be hard to improve on the very potent ZR1 Corvette since it comes from GM with 638 hp, but it is possible. The Corvette engineers did a fantastic job of bringing us an awesome car, but they also gave us something capable of more. The Zip Corvette ZR1 Corvette LS9 Power Package brings together our exclusive set of Kooks R-Series stepped headers and high flow stainless steel converters backed by a Corsa Sport exhaust system to give the ZR1 Corvette some authority out on the road. Along with a supercharger pulley upgrade kit, Mamba fresh air scoop, Zip performance shielded spark plug wires to keep the heat off, and some calibration changes in the PCM; this performance package will turn your ZR1 Corvette into a 700 horsepower beast. You will also notice quicker acceleration thanks to an additional 5lbs. of boost and free breathing on the exhaust side.
Check out each performance Corvette Part included in our ZR1 Corvette LS9 Power Package:
 Mamba Fresh Air Scoop |
The Mamba Fresh Air Scoop allows the ZR1 Corvette air intake to achieve it’s full potential by ramping fresh air from the front of your ZR1 Corvette directly into the opening of the intake. The Mamba Fresh Air Scoop is mounted to your ZR1 Corvette’s radiator shroud with 3M double sided tape. |
 ZR1 Corvette SuperchargerUpgrade Kit |
The Lingenfelter ZR1 Supercharger Pulley Upgrade Kit is designed to enhance the LS9 Corvette ZR1 supercharged engine. This upgrade kit produces excellent horsepower and torque improvements over the factory 638 horsepower and 604 lbs. ft of torque while maintaining a safe level of boost and supercharger RPM. |
 Performance Corvette Spark Plug Wires |
These Hi-Performance spark plug wires are built to Zip’s standards, built specifically for Corvettes with headers. We start out using a Delco Mag wire and then heat shield it with some of the best products the aftermarket has to offer. This will be the last set of wires you will ever have to replace from getting burned by a header or just plain wearing out. These C6 Corvette spark plug wires are the perfect compliment to the Kooks Stepped Headers also included in this LS9 power package. |
 ZR1 Corvette PCM Programming |
To go with all of the upgrades to your LS9 Corvette engine, we will also upgrade your ZR1 Corvette’s PCM. With custom PCM programming using HP Tuners scanning and diagnostic tools we can modify just about any setting available within your ZR1 Corvette’s computer system. |
 Kooks ZR1 Corvette Stepped Headers |
If you really want to step up your Corvette’s exhaust system then consider a set of Kooks Custom Headers from Zip Corvette. Kooks Stepped Header design, which is included in this power package melds the particular advantages of specific tube diameters: low end torque from 1 3/4″ primaries at the flange, then opening up to 2″ tubes for unrestricted top end. Built by Kooks Custom Headers, manufactured from mandrel bent 304 stainless steel with 3/8″ flanges and 3″ collectors. Stepped headers include O2 sensor bungs, gaskets and sensor extensions. |
 Kooks ZR1 Corvette Mid-Section |
This mid-section is designed to complete installation of Zip/Kooks R-series “stepped” headers on LS9 equipped Corvettes. The mid-pipe bolts directly to the 3″ collectors and allows you to utilize the ZR1 exhaust system of your choice; in this case the ZR1 Corsa Sport. The 304 stainless steel center section includes a crossover pipe and hi-flow stainless steel converters for a completely street legal performance exhaust system. |
 Corsa Sport ZR1 Corvette Exhaust System |
Also included in the LS9 ZR1 Corvette Power Package is the clean-sheet engineered C6 ZR1 Corvette Corsa Sport Exhaust System. Corsa’s famous sport system includes a race car like sound at full throttle yet a calm sound great for cruising speeds, military grade 321L stainless steel, and an increase in horsepower and airflow over the stock application. The quad 4″ exhaust tips finished with the Corsa logo adds the finishing touches to this near perfect Corvette exhaust. |
ZR1 Corvette W/LS9 Power Package
Take a look at a couple of our before and after dyno runs of a customers ZR1 Corvette with our LS9 power package installed. As you can see in the graph the ZR1 Corvette was producing 429 rear wheel horsepower and 410 ft-lbs. of torque at 5500 rpm (red). After installation of our ZR1 Corvette Power Package the ZR1 produced 534 rear wheel horsepower and 510 ft-lbs. of torque at the same 5500 rpm (blue). That’s an improvement of over 100 horsepower and 100 ft-lbs. of torque on a stock ZR1 Corvette. Not only did this ZR1 produce greater numbers but it sounded like a pure race car with the C6 Corsa Exhaust System, Kooks Headers, and Kooks Mid Section. So if you thought adding to your ZR1 Corvette was impossible you may want to think again. Our power package will make any stock ZR1 accelerate faster and produce approximately100 more horsepower to the rear wheels.
