GFB have re-designed their WRX lightweight pulley to provide even more benefits. It is now shaped to look exactly like the factory Subaru pulley, so it goes unnoticed in your engine bay - it even uses the factory belts! A significant amount of weight has been removed from around the rim for even better throttle response. The pulley weighs in at 578g (previously 790g), compared to the factory 2180g on the WRX and 2575g on the STI. This pulley will improve throttle response (particularly off-boost response) and allow the engine to rev more freely in the upper rev range.

It suits all Subaru EJ-series engines, and does not require additional belts

What's your ethanol percentage?
The ethanol content of E85 fuel can vary from 60% to 92% ethanol. A fill up with E85 can drastically change the mix of fuel in your vehicle.  For performance drivers determining actual ethanol content of E85 is essential to maximizing an engine tune and horsepower.

Why know your ethanol percentage?
E85 has the equivalent octane rating of 105 or higher octane fuel.  Higher octane fuel is more resistant to knock allowing for more aggressive ignition timing, higher compression and increased engine power over gasoline itself. 

The Zeitronix Ethanol Content Analyser helps you get the most out of your engine and fuel.

• Two 0-5 V analog outputs: Ethanol % and Fuel Temperature for use with ECUs, data logging and engine management systems.
• Connecting harness to Zeitronix Flow Through FLEX Fuel Sensor is included. Harness length is 8 ft (2.4m)
• Optional real time E% Ethanol Content Gauge.
  The E%  gauge is only 3/4" (19mm) thick. The back of the gauge is completely flat with cable hidden in a cavity and can besurface mounted almost anywhere inside the car cabin using a piece of Velcro or double sided tape. The E% Gauge base allows the gauge to be mounted in a standard 2” 1/16 (52mm) gauge pod. For additional mounting options the package includes 2 set screws and 2 nuts (4-40 screw size). Check out the gallery for gauge installation pictures.
  The E% Gauge plugs into the ECA-2 GAUGE port. Power and serial data is supplied directly through the single connection - there are no additional +12V or ground wires. The E% Gauge cable length is 5 ft (1.5m).
  ECA-2 is required for E% Gauge operation.
• A flex fuel sensor is required.  The ECA-2 is compatible with some OEM sensors used in GM vehicles with the flex fuel insignia or which run on E85. However GM offers a large number of different sensors with different specs.

What are the sizes of the flex fuel sensor inflow and outflow lines?
Zeitronix Flow Through Flex Fuel Sensor both tubes are 0.37" and 0.5" at the flange.

The usual mounting location for the sensor is the return fuel line.  Make sure the sensor is filled completely with fuel.
A professional installation by a shop familiar with your vehicle and it's fuel system is required. Always check for fuel leaks!
