ESS Mustang S550 GT G2 Supercharger Tuner Kit

The intercooled ESS Tuning S550 GT 5.0 supercharger system is the culmination of over 25 years of forced induction experience. The G2 supercharger has a max capacity of 1300CFM, and is ideal for the Coyote application in power ranges of 575-800WHP. Featuring the patented, highly efficient, extremely durable and light weight ESS G2 supercharger unit. This system delivers quick boost, a very strong mid range and considerably less mechanical noise vs competing systems. It is also extremely light with the entire system weighing in at 35lbs total weight, so it is ideal for racing applications where weight balance is a major concern.

The system utilizes a 27mm thick structurally engineered high pressure die cast main bracket assembly for zero flex, a 6rib belt drive system with billet idler pulleys and premium quality SKF idler bearings for extended service life, a 3" front mount intercooler (FMIC) that is designed to fit without modification to the OEM front bumper and it features an integrated high capacity 50mm off valve. The S550 G2 supercharger system is a complete system with everything you need for correct installation besides injectors and software. For heavy duty applications we recommend adding a quality PCV catch can setup as well.

Power delivery is 100% smooth and of OEM standard when correctly calibrated. The system comes standard with high precision straight cut gears which have a cool, although modest whine to them. Even more quiet synchro gears are available as an option.

And like all ESS supercharger systems, the S550 Coyote kits are extensively tested and guaranteed for 1 year against any hardware malfunction or defect regardless of mileage. We offer a full spare part and upgrade part web shop for this system as well under our parts and maintenance section. Support is only offered on the supercharger hardware side, we refer to your tuner for any operational guidance as far as powertrain integration/calibration goes.

This system is for clients that have the skill set to install and arrange the calibration on their own, and it is not meant as a complete package with full operational support for people with no experience in powertrain modifications. Quality throughout the kit is absolute top notch as is the system capacity and efficiency. This is a fantastic option for the enthusiast who is looking for a rock solid foundation to build his dream setup from.

The kit can easily be upgraded to G3 spec by simply swapping the impeller and SC volute and by adding the larger G3 spec intercooler. All other components between the systems are the same.

The optional 10PK drive system upgrade is available for both G2, G3 and G3R systems as a direct bolt on upgrade. The standard bracket and idler system is already prepared for 10PK operation, but it is only recommended for extreme racing conditions or when power output approaches 1000HP.

Standard kit colors are satin intercooler (black available on request at $50 extra cost) and satin bracket system/supercharger. Black supercharger available as an option.

We can provide the MAF transfer table developed for this kit at no cost for custom tuning applications.

For normal lead time estimate please check terms and conditions page.

Recommended pulley size :

Gen.2 Coyote 120mm/115mm for 91AKI/93AKI. E85 down to 105mm.
Gen.3 Coyote 125mm/120mm for 91AKI/93AKI. E85 down to 100mm.

Boost vs pulley size is rated at 7200RPM using a G2 supercharger at sea level/68F, if you run higher RPM limit than this, or a larger head unit then boost will also be higher than rated so keep this in mind when selecting pulley size. Elevation and warmer air than rated will bring peak pressure down.

Kit options: choose your pulley/boost level and finish above. Extra ESS factory upgrades (injectors, fuel system, impeller, quiet gear and more) are listed in the add-ons box on this page at ESS's with-kit prices. The standard 50mm blow-off valve is included.

This is a tuner kit: calibration is not included and must be arranged with a qualified tuner. ESS builds kits to order; most ship within 2–4 weeks.
