ESS Tuning S65 G1+ Intercooled Supercharger System

The intercooled S65 G1+ Supercharger System produces a massive 180-220whp gain from stock depending on exhaust system and methanol injection used. It is supplied with both 93AKI/98RON and 93AKI/98RON + methanol injection pulleys as standard. It is very important to understand the risks when running the high boost pulley as the engine can be damaged from lack of proper methanol flow or if it is not in 100% condition internally. This is pushing the limits of the stock S65, so everything must be spot-on.

This kit is designed for 93AKI/98RON fuel or above exclusively, in order to use the included high boost supercharger pulley a methanol injection system must be installed. We recommend the Snow Performance Stage 2 system using the #5 nozzle set to 3PSI start and 7PSI full gain. Torqo or VP methanol is recommended. We do not sell or support the methanol side of the system, so please ensure you find a competent supplier/technician with experience on these injection systems. No operational support is offered on the G1+ kit besides hardware support directly related to the ESS supplied parts.

This kit is based on the S65 G1 supercharger system and contains all of the same components with the exception of :

ESS S65 G1+ specific 7rib beltdrive system with all billet pulleys and idlers. 128mm crank pulley.

ESS G1+ spec fuel injectors

Perfectly optimized, dyno tweaked MSS60 ECU software with removed top speed governor, calibrated for G1+ spec injectors

7PK S65/98mm (93AKI/98RON) and 7PK S65/94mm (93AKI/98RON + methanol) supercharger pulleys are included. 92, 90 and 88mm pulleys available on request for custom use.
