Lethal Performance 07-08 GT500 Ultimate Pack with JLT Carbon Fiber Intake
The Lethal Ultimate Pack is the most complete and most efficient package on the market for the GT500. While others offer similar power packages with intakes and tuners no one but Lethal Performance offers the most important part of upgrading your Shelby.

COOLING When adding all this power by upping the boost and flowing more air it's most important to keep things cool. The most common culprit of power loss it heat soak. Heat soak causes you to continually lose power as your car warms. The IAT temps rise and the cold air needed to make power goes bye bye. Another thing that happens after several hard runs on the car is the computer senses the higher temperatures and pulls timing. Obviously it does this to prevent overheating and dangerous lean conditions as well as detonation.

Whats the solution? Cooling Mods Lethal Performance is the exclusive distributors for the all new AFCO Pro-Series Heat Exchanger and PFAB Intercooler Reservoirs. Both of these combined offers just what your car needs in the cooling department.

Adding more coolant to the intercooler system will help dissipate heat. In addition to the added volume of fluid you'll be cooling that fluid with a much larger surface area of cooling fins. How many rows of fins? 19... That's right 19 rows of cooling fins in addition to the fluid passing through the AFCO's Double Pass design. No other heat exchanger on the market is as large or efficient as the AFCO Pro-Series Heat Exchanger.

In addition to adding the AFCO Pro-Series Heat Exchanger we've also included the PFAB Intercooler Reservoir. The PFAB Intercooler Reservoir is tig welded out of the highest quality aluminum available. Precision welds and an amazing design allows this tank to replace your stock plastic reservoir with a much nicer looking and functional piece. The PFAB tank holds just under 1 gallon of fluid. This is a major increase over the stock tank and the increased fluid will help every bit in keeping the rest of the system cooler. You're also able to fill this tank with ice between runs at the track to help cooling and lower intake temperatures which has been dyno tested and proven to add horsepower. Best of all the PFAB Intercooler Reservoir is a direct replacement which is very easy to install.

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

Allows for use of the stock belt when upgrading to a Smaller Supercharger Pulley

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.

AFCO 2007+ GT500 Pro-Series Dual Pass Heat Exchanger

OFFERED EXCLUSIVELY THROUGH LETHAL PERFORMANCE!!

All new from AFCO is the Pro-Series Heat Exchanger for the 2007+ Shelby GT500. If you didn't already know AFCO currently makes the best selling and best performing heat exchanger for the 2003-2004 Mustang Cobra. Well they're going to do just the same for the GT500 by offering the same technology and quality with their Pro-Series H/E.

When dealing with Roots or Twin Screw Superchargers there's always the issue of intake temps. When running the car hard and spinning the blower fast you create heat. Heat equals a loss in power as well as the possibility of damage to the engine. One way to help reduce these intake temps and the risk of damage is to add more fluid into the intercooler system which in turn helps lower intake temps by dissapating heat.

Whether it be on the street or at the track the warmer the car runs the more timing gets pulled. In addition to that an excessive amount of heat known as heat soak starts to take place. This keeps the car down on power and running less efficient. This again can be helped by adding more fluid into the cooling system. The temperature of the intercooler fluid will lower and cool down faster in between runs.

Here is a rundown of AFCO Pro-Series heat exchanger vs. Stock:

Core Size
AFCO core is 9" tall x 22.44" wide x 2" thick.
Stock is 6" tall x 23" wide x 1.25" thick.

Cooler intake temperatures mean more power. It is just that simple. However, providing your engine with cool air to breathe becomes even more difficult when forced induction is involved.

Ford's potent supercharged V8 is no exception. This is why Ford designed a separate intercooling system for the supercharger on their popular F150 Lightning, Shelby GT500 and 03-04 Mustang Cobra.

The Ford system utilizes a heat exchanger mounted low in the front grill, which is very similar to a small radiator. Coolant flows separately from the main engine cooling system and circulates internally through the intercooler beneath the supercharger.

While the factory supercharger cooling system is adequate in stock configuration, it struggles to keep up with the multitude of popular modifications that not only deliver more power, but also increase the stress and strain on the engine.

To combat the power loss by excessive heat build up in the supercharger and intake system, AFCO focused on upgrading the weakest component in this cooling system: THE HEAT EXCHANGER.

AFCO Heat Exchangers are considerably larger than their stock counterparts. This provides a greater surface area and more capacity. AFCO Heat Exchangers reduce supercharger coolant temperatures by more than 40 degrees.

True Bolt-In Installation No Cutting • No Drilling • No Welding • No Headaches
AFCO Heat Exchanger installation only requires simple hand tools and approximately 30 minutes. All needed hardware (except replacement fluid) is included, along with detailed instructions.

Easy Bolt-In Installation
AFCO Heat Exchangers mount in factory locations with no drilling, cutting or fabrication of any kind – a TRUE BOLT-IN.

Regains Lost Power
By more effectively cooling intake temperatures, AFCO Heat Exchangers keep the air entering the combustion chamber cooler and more dense, even in high-demand situations.

Allows for More Consistency
After hard acceleration, especially in drag racing applications, AFCO Heat Exchangers allow the supercharger to cool faster and remain at a constant temperature, which means power delivery is more consistent.

Optimized Design
Using years of experience, advanced design, and thorough testing, AFCO Heat Exchangers are designed to promote optimal air flow and cooling by utilizing appropriate fin count, tube size, core thickness, and fin serration for each particular application.

Quality Construction
Of course, as an AFCO product, quality is second to none. AFCO Heat Exchangers are TIG welded and feature furnace brazed cores with no epoxy. Each unit is pressure-tested before it is shipped.
