Lethal Performance is proud to offer our own line of performance packs for the 07-08 Shelby GT500.. Custom tuning along with the industry's highest quality parts is what we've got for you. All of our custom tuned Xcal 2's, 3's and Livewires come with performance enhanced tune files from Justin Starkey at VMP Custom Tuning. Not only is Justin one of the most well known SCT tuners in the industry but also a GT500 owner himself. This has allowed him to do extensive dyno testing with many different combinations to come up with the special recipe for awesome power and excellent driveability.

JLT Carbon Fiber Intake:
JLT's all new Shelby GT500 induction kits are made from real carbon fiber and high grade billet aluminum.

The upper intake body is made from hand laid carbon fiber for strength, weight and looks. It’s able to retain the stock strut tower brace and out flow the stock pipe by a mile.

JLT took the carbon fiber one step further and professionally prep and clear the bodies for a super gloss shine. They just pop!

This is mated to the throttle body and MAF housing with high quality silicon hose couplers and stainless clamps.

The custom JLT MAF is CNC milled from high grade aluminum to the perfect size for max power, whether your only doing a intake and tune or going all out with a pulley swap, exhaust, intake and tune. We then anodize them in a black hard coat for a clean stealth look

The JLT MAF is connected to an S&B Powerstack air filter and supported by a stainless support bracket.

Metco 2007+ Shelby GT500 Interchangeable Supercharger Pulley

Metco Motorsports Interchangeable Supercharger pulleys for your all new GT500..How it works is the smaller diameter of this pulley allows the supercharger's rpm's to increase. This in turn allows the supercharger to flow more air and create more boost pressure which makes power. The Metco pulley design uses a hub and ring style setup. This means you press the hub onto the superchargers shaft and then bolt the pulley ring to it with allen bolts. The hub and ring design allows for quicker pulley changes which can be done in less than 5 minutes.

The Metco GT500 Supercharger Pulleys are offered in a 2.60" and 2.80" size to add more boost and simply gain more HP and TQ across the board..

Typical Boost gains:
2.60" adds 4lbs of boost
2.80" adds 2lbs of boost

In stock and ready to ship.

NOTE: When using either the 2.60" or the 2.80" pulley you can use your stock belt by using the Metco Auxiliary Idler Kit

Metco Motorsports 07+ Shelby GT500 Auxiliary Idler Kit

Lethal Performance is proud to offer the Metco Auxiliary Idler Assembly. The Auxiliary Idler kit is designed to provide maximum belt contact of the supercharger pulley, thereby decreasing the amount of belt slippage in high boost situations.

FEATURES:

CNC machined from 6061 T-6 Aluminum for Accuracy and Detail

"Hard Coat" Anodized Idler Pulley for superior belt wear protection and bearing bore hardness

Top Notch OEM Quality Sealed for life bearing

A must when using a smaller supercharger pulley on your Shelby

Works with 2.8 and 2.6 Supercharger Pulleys

Comes complete with easy to follow instructions and hardware

Fits perfect with no modification necessary

NGK TR6 Spark Plugs- These are a must when upping the boost with a smaller supercharger pulley. The more boost you make the hotter the intake temperatures get. The TR6 spark plug is 1 heat range colder than the GT500 spark plug. This helps to cool the intake charge in the combustion chamber which helps to prevent detonation. The ideal spark plug gap for the GT500 running either the 2.60" or the 2.80" pulley is .035.
