Are you running more E85 or making more power than your stock fuel system can support?
We have developed a port injection kit and LPFP upgrade (Low Pressure Fuel Pump) for your S55 that will provide you with the additional fueling capacity that you need to be able to run up to 100% E85 on stock or upgraded turbos.
What is port injection?
Port injection is a kit that is installed between your intake manifold and the cylinder head that runs off the low pressure fuel supply to provide you with more fueling than your stock system is capable of. It's a relatively easy system to install and does not require any permanent modification to your car.
What is the Stage 4 LPFP upgrade?
This upgrade is an E85 compatible dual pump system that doubles the factory capacity and is required when looking to make more than 600whp on E85.
Stage 4 kit includes:
Compatible with the following:
*Port Injection Controller install guides can be found here...
*These kits are available for off-road use only
*All port injection kits are built to order so please allow 5-7 business days for shipping.
*Ethanol Sensors don't actually read the ethanol content, the readings are based on the absence of gasoline, so if your fuel is contaminated, your ethanol readings may be artificially elevated.
