When asking the question, “Why does a person own a truck?” the answer is simple. It’s because we want a vehicle that can do anything and everything. As a truck owner we want to be able to haul friends/family, we want to be able to tow toys around, we may need to throw stuff in the bed, and to top it all off we still want our trucks to be FAST!

So with the diversity of how a truck gets used, doesn’t it make sense that your power adder should be just as versatile? Of course you do, which is why ProCharger invented the award winning i-1 supercharger. With a simple “swipe” of the finger on your touch screen you can not only dial in the boost that best fits what you are doing, but also the boost curve itself!

This 2007-2013 GM Truck/SUV system has two intercooler location options, horizontal and vertical. The horizontal unit is mounted below the truck for those that prefer the “stealth” look, and the vertical unit is mounted behind the grill for those looking to make a statement. For customers wanting to push the HP levels and boost levels up, an even larger vertical intercooler can be purchased.


For those of you with the HD trucks we haven’t forgot about you either. We will be rolling out the i-1 supercharger system for the GM 2500 trucks with the rock solid 6.0L engine platform as well.


The ProCharger i-1 supercharger system not only delivers performance, but simplicity.

- Easy bolt on install

The system comes to your door with everything you need to bolt the system on in your garage. No complicated exhaust work, No cutting or trimming, No fabrication, No hassle. Even the simple air-to-air intercooler is a bolt on item, vs. time consuming air to water intercooler installs. For the i-1 itself, a simple plug-n-play harness is provided to connect the i-1 supercharger to the programmable control box

- Programable Boost Levels

Not only are the boost levels programable, but they are also adjustable on the fly from inside the cab via the touch screen or dial. No pulley changes, No boost controllers, No drama. Imagine you are towing a 7,000lb trailer, and get in an area with bad fuel where running full boost isn’t possible. With the i-1 you can instantly turn down the boost, to make sure your engine is protected even in a situation such as this.

- Programable Boost Curve

The i-1 supercharger not only allows a person to pick the boost level of their choosing, but also the “curve” of how the boost comes in. Having this ability can help you tailor your curve for traction limited conditions or towing.

- Large air-to-air intercooler

For the best cooling of the charge air going into your motor, the i-1 features a large highly effective air-to-air intercooler in the system. These intercoolers easily bolt right in, and are not complicated with no water reservoirs to fill/bleed and no pumps to fail.

- MPG Increases

Thanks to the efficient design of our supercharger and quality ECU tuning, many of our customers report great gains in fuel economy. Not many people purchase a supercharger to save a few $$ at the gas pump. Though its a good peace of mind to know your install is not going to hurt you at the gas station either.



“.. one of the most radical concepts we’ve seen in many years: ProCharger’s i-1 programmable-ratio supercharger. This patented centrifugal unit - unlike any blower before it - allows drivers to dial-in variable boost ratios on the fly.
- 5.0 Mustangs and Super Fords, June 2013


"ProCharger’s new i-1 centrifugal supercharger is a Kansas-born wonder of the technical variety. It was introduced to the world in November of 2012, and earned runner-up honors as one of the best new performance-street products that were unveiled at SEMA." - Muscle Mustangs & Fast Fords, May 2013


"ProCharger is changing the game with their i-1 variable ratio supercharger." –, April 2013




Intelligent Boost:
Bolt on 205-235 HP to Stock 5.0L 4V & LS3 Motors, with 7.5 psi


“This is the most creative new product launch we’ve seen so far at SEMA 2012...[and] you have to check out the video to really understand how cool it is” – Hot Rod Magazine


"ProCharger has a history of innovation, but the revolutionary i-1 is a true pioneer"
- Muscle Mustangs & Fast Fords, May 2013


"Programmable boost means you can literally dial in the boost curve as you desire and can make boost adjustments [via multiple modes] on the fly using the digital touchscreen."
- GM High Tech, April 2013


"Unprecedented technology? It most certainly is! Never before have we seen a bolt-on, intercooled, centrifugal blower with this type of programmable-ratio capability"
- 5.0 Mustangs and Super Fords, June 2013


"ProCharger has stepped up to the plate to create a product that’s undoubtedly one of the most revolutionary designs available in the aftermarket." - LSX TV


"Is this the perfect supercharger?" – Muscle Mustangs & Fast Fords, May 2013


This latest addition to the ProCharger line produces not only the largest power gains, but also the ultimate performance curve. 


With an intelligent control system and an optional touch screen display, drivers can switch between 3 factory supplied performance modes, as well as a custom mode.  Personalized display screens and data logging are also available.


Building on the benefits of centrifugal design, the i-1 delivers higher compressor efficiency than screw blowers, utilizes the most effective intercooling, and avoids the heat transfer associated with engine-top mounting or an exhaust interface.


Air-to-air intercooling is standard, and as experts agree, inherently provides better cooling and reliability than air-to-water intercoolers for street use.


Due to these advantages, i-1 technology delivers the coolest charge air, the most power with greatest repeatability, and best in class fuel economy. Similar to P-1SC-1 and D-1SC supercharger systems, i-1 ProCharger systems produce far more power per psi of boost than air-water-intercooled positive displacement supercharger systems.  Continuing the ProCharger tradition, i-1 supercharger systems also feature a broader operating range than PD blowers, and greater upgradability. The i-1 ProCharger is designed for both stock and modified applications, and supports up to 900 flywheel horsepower.


The patented programmable i-1 design produces immediate response, even at low engine rpm, without any turbo lag or boost falloff at higher engine rpm. To further increase performance, competition mode can be quickly selected, and owners can use the touch screen to lock the supercharger in low ratio mode or select a personalized mode.


Designed and manufactured in the USA, i-1 ProChargers feature exclusive billet impellers and rugged gear cases. Programmable boost is delivered by a highly durable variable ratio transmission design, with a rugged dry hybrid drive. Proven in over 4 years of intensive R&D and rigorous performance testing, the i-1 is available with ProCharger’s optional 3-year supercharger warranty. i-1 supercharger systems are 100% complete, and are backed by ProCharger and its network of dealers.


With an unmatched combination of technology, product options and winning experience, ProCharger is the Ultimate Power Adder.

ProCharger i-1 Testing:

Proven Durability



Proven Performance and Durability

The ProCharger i-1 supercharger has been rigorously tested in the lab, on the dyno, on the street and at the track. Lab testing began in 2010, while dyno and track testing, as well as daily driving of the company’s test fleet, began in 2011. ProCharger i-1 models are available with the same industry-leading warranty coverage as the legendary P-1SC-1 ProCharger, as well as self-contained oiling–a design feature that ProCharger pioneered over a dozen years ago.

Smaller and lighter than both intercooled positive displacement supercharger and twin turbocharger kits, the award-winning i-1 ProCharger is available as a tuner kit or 100% complete system. This proven supercharger has received an extreme amount of praise from across the industry for providing the largest power gains per psi, as well as several industry exclusive features.

The blue Camaro, above, is the third vehicle driven from Kansas City to Florida, for track testing with Super Chevy. On the left is the GM High-Tech Performance project Camaro, which has been run on the road course extensively since the i-1 was installed. Both cars gained 195 RWHP with the i-1, running 7.5 psi on stock LS3’s with stock exhaust and pump gas.
