Redpants HIGHLY recommends an upgraded clutch be used with these supercharger kits. The factory single-plate clutch won’t last long with all the extra torque!

This product is designed for off-road use only.


Professional installation is required. Expect it to take approximately 2-3 days from start to finish.

A handheld module is provided with the supercharger kit. It is used to plug into your car and download the current tuning files. These need to then be transferred to a PC and emailed to GMR. GMR will evaluate the files and then create a new file specifically tailored for the supercharger kit, which will be emailed back to you. You can then take that file and upload it to your car and you’re ready to roll!

GMR’s cats are required for this product. Use of non-GMR cats will void any and all warranty.


Is the supercharger kit safe and reliable?

Yes. GMR have put years of testing and development into their products. Their own development car has been supercharged for 115,000 miles and counting. The tuning was done with safety and engine longevity as a key requirement.

Does the supercharger kit include an intercooler? How is the intake charge cooled?

No, this kit does not use an intercooler. Rather, it uses water injection to cool the intake charge. An added benefit of water injection is that it helps keep the engine’s internals clean. You’ll need to fill up the water tank occasionally, but there are filters in the system so normal tap water will be fine for it.

What happens if the water tank runs dry?

There’s a level sensor inside the water tank. If it gets too low, an indicator light will warn the driver. When the water tank is empty, the supercharger will disengage and the engine will act as a naturally aspirated engine so you can carry on driving. Once the water tank is refilled, the supercharger will reengage.

Will the supercharger kit change the way my car sounds?

No. The supercharger is part of the intake system, so it has no effect on the sound of the exhaust. The “whine” that many superchargers have is not found in this one, so the intake sound is not changed, either. GMR’s high-flow cats are required for this system and included with it. They may make your exhaust a little louder if your car currently has the OEM cats in place.

Are these supercharger kits CARB compliant?

The two primary concerns of CARB testing are exhaust emissions and fuel economy. MOT* testing has shown a drastic reduction in emissions, and real-world testing shows greatly-improved fuel economy (in general, a 20% increase in MPGs). Although I’d expect GMR’s supercharger kits to pass CARB testing with flying colors, that is an expensive and time-consuming process. We aren’t ruling out having it done in the future, but we do not have any immediately plans for CARB certification.

*MOT is the Ministry of Transportation, the British version of the US’s Department of Transportation (DOT).

I already have high-flow cats on my car, do I have to replace them with GMR’s own cats?

Yes. GMR did test cats from other companies and found that they had a very high failure rate due to being unable to cope with the supercharged exhaust flow. It doesn’t matter if you have OEM or high-flow cats on your car, you’ll need to replace them with GMR’s cats (included in the supercharger kit).

Do I need an upgraded clutch?

Technically, no. That said, your original clutch won’t last long with the massive increase in torque, so you might as well bite the bullet and upgrade at the same time so you can enjoy your supercharged Vantage stress-free. I’d recommend the clutch package from VelocityAP.

Aside from an upgraded clutch, is there anything else I need?


The big question: Why get this instead of trading up to a V12 Vantage S?

A supercharged V8 Vantage has more horsepower, more torque, less weight, better weight balance, better fuel economy, lower emissions, and easier maintenance than a V12. Plus, you can easily get a V8 Vantage with a manual transmission – the V12 Vantage S is very hard to find with a manual and far more expensive, too.
