Stage 2 Intercooled System with P-1SC-1 (satin, dedicated 6-rib drive system)

Corvette C6 Stage 2 Systems, Bring on the POWER!



Over the years the power levels of Corvette C6’s with ProCharger superchargers have been pushed from 550rwhp to a mind-blowing 1,491rwhp!

A little while back we released our new “Race” air-to-air intercooler, which has already been destroying the dyno rollers to the tune of 1,457rwhp!

With these big power cars becoming the norm nowadays, ProCharger has added a Stage II C6 Corvette system to the product lineup. Read on to find out the differences between the Stage II system and the HO system.


With big power comes the need for big airflow to the blower. The Stage II Corvette system will come with a 4.00″ inlet tube combined with a high-flowing, reusable air filter.



The #1 enemy of any high HP supercharger system is belt slip. The longer the drive belt is, the more it will grow as power is applied to it. To keep the ProCharger drive belt short, we have incorporated a direct drive as an option into the Stage II system. By adding a direct drive belt system to the ProCharger, we are able to decrease the overall length of the belt by over 40%, creating an ultra-strong grip.


Note: The Stage II and the race kit both are the direct drive.  The Stage II is a 6 rib std. with the factory balancer, the 8 rib is optional but will need to purchase an ATI damper.

8 rib upgrade is required when opting for the F series head unit upgrade.

ATI Performance Products 917345 harmonic balancer is required for standard LS3 Corvettes.

ATI Performance Products 918620 harmonic balancer is required for Grand Sport models.

Direct Drive 2009-13 models require ProCharger water pump pn#AIG02I-030.


ProCharger also made sure that the accessories were given a strong OEM spring loaded tensioner. Using a spring loaded tensioner ensures that the accessories will have the proper belt pressure applied to them as the belt wears and grows over time.


To make installation of the accessory belt easy, we have also included an extra “boss” built into the bracket to allow for better leverage to release the tensioner. Once tension is off the belt, the belt can be easily slipped over the alternator pulley.

Yes, even the race intercooler that we launched in 2014 can be purchased as an upgrade to existing kits, or as an option when purchasing a new system.





Industry Leading Power
With ProCharger technology, reliably adding big horsepower to your engine is a lot easier than you may think. Intercooled ProCharger systems utilize exclusive features and proven technology to deliver reliable 50-85% gains in horsepower and torque with stock motors running pump gas. ProCharger technology is proven to produce the industry's largest power gains and coolest charge air temperatures, and ATI is also the only company that guarantees the best performance gains. Nothing else even comes close! For modified street applications, ProCharger technology delivers 10-second ET's with the least amount of engine modifications - and with the supercharger still under warranty. For highly modified applications, ProCharger is the undisputed leader, and is over 800 horsepower ahead of the competition. Superior products yield superior results.

Advanced Design
The patented SC design eliminates the need for oil lines and punching a hole in the oil pan. Additionally, instead of being forced to utilize heated engine oil or the grease in sealed bearings, SC ProChargers are lubricated with an extremely high quality synthetic oil which is specifically engineered for high speed use, and produces the least frictional heat and parasitic load. The self-contained design not only eliminates the heat that is transferred to a supercharger by engine oil in oil-fed applications, it also avoids the risk of clogged supercharger oil lines, oil drainage problems, or engine oil leakage. By combining an advanced multi-patented supercharger transmission design with the highest quality oil, SC ProChargers produce a larger net power gain because they run cooler and consume less power than comparable oil-fed designs. Both street and strip ProCharger models are also the most durable superchargers available, and are backed by the industry's best warranty coverage.


Fuel mileage

A supercharger will decrease the fuel economy of your vehicle, right? WRONG!!

Although roots superchargers have significant parasitic load and do dramatically decrease fuel economy, centrifugal superchargers (like ProCharger) will yield approximately the same fuel economy as normally aspirated engines under normal throttle conditions. This means that after the installation of a ProCharger intercooled supercharger system, if you drive your vehicle in the same manner as you did before the installation, you should see no drop in fuel economy and in some cases customers with heavier vehicles have actually increased their fuel economy because of less frequent downshifts! However, the purpose of the supercharger is to get more air into the engine…and when you add air you must add fuel. So when you stand on the throttle and that impeller starts force-feeding your motor the air it deserves, your fuel system will allow more fuel in to create gobs of Grandma scaring horsepower. It is during those moments when supercharged vehicles see a drop in fuel economy.

To explain further, a supercharged engine operates at a much higher power and efficiency level than a naturally aspirated engine. So why, under normal operating conditions, would making an engine more efficient decrease fuel economy?

ProCharger has a large and ever changing fleet of test vehicles running the streets and race tracks every year. We use these vehicles to test everything you would expect from a company like ProCharger…durability, aesthetics, noise, drivability, power. What you may not expect is that we also collect fuel mileage data on these test mules. A small snapshot of some of our data is below.

  • 2005 Mustang V6
    • Intercooled ProCharger P-1SC
    • Automatic Transmission
    • Factory Mileage Claim: 19 City/25 Hwy
    • ProCharged Fuel Mileage: 22.55 mpg
  • 2004 Corvette Z06
    • Intercooled ProCharger P-1SC-1
    • Manual Transmission
    • Factory Mileage Claim: 19 City/28 Hwy
    • ProCharged Fuel Mileage: 21.00 mpg
  • 2007 Mustang GT
    • Intercooled ProCharger P-1SC-1
    • Automatic Transmission
    • Factory Mileage Claim: 18 City/23 Hwy
    • ProCharged Fuel Mileage: 19.59 mpg
  • 2006 Dodge Charger 5.7L HEMI
    • Intercooled ProCharger P-1SC-1
    • Automatic Transmission
    • Factory Mileage Claim: 17 City/25 Hwy
    • ProCharged Fuel Mileage: 21.00 mpg

The majority of the above data was taken during mostly highway driving on the 2007 Hot Rod Power Tour. As you can imagine, fuel mileage was not the main concern of our drivers when cruising along side the amazing cars that grace the Power Tour. The Dodge Charger fuel mileage was recorded on a recent roundtrip from Kansas City to Tampa, FL. Also, keep in mind that the above vehicles are all stock with the exception of the intercooled ProCharger system. Your fuel mileage may vary depending on your vehicle combination and driving habits.

2001 Chevrolet Silverado customer testimonial after the installation of a P-1SC-1 Intercooled ProCharger system.

“My gas mileage has increased nearly 1 mpg on my annual trip from Michigan to Alabama, from 16.19 mpg naturally aspirated to 17.06 mpg with the ProCharger. Considering these trips are taken during Christmas in the winter with periods of idle time and speeds with the flow of traffic the ProCharger actually helps gas mileage. Add the extra on demand power and the smiles per gallon, the truck makes the trips fun!”

2006 Hemi Ram customer testimonial after the installation of a P-1SC-1 Intercooled ProCharger system.

“I’ve got 34K miles on the supercharger system in the past 9 months, and it’s great. I pass other trucks on hills all the time while towing Bobcats and other heavy loads. And my fuel economy is about the same as it was before, but with a lot more power.”
