HOW IT WORKS
Once the AEM Water/Methanol Kit is installed, a boost-dependent, variable-flow progressive controller allows the user to determine the amount of water/methanol mixture (up to 50%) to feed into the inlet stream from the fluid reservoir. The controller commands a high-pressure, recirculation-style 150-PSI pump that delivers the mixture. Overall flow adjustments at the inlet are made via one of three different-sized jets (included) that are designed to match most engine power requirements.
RECIRCULATION-STYLE PUMP
AEM's recirculation-style pump offers improved performance, reliability and a much smoother, quieter operation when compared to older switched-style pumps. With the use of a new internal bypass design, AEM's upgraded pump eliminates erratic on and off switching/pulsing and ensures consistent fluid delivery for optimum performance. With durability and reliability in mind, AEM has designed the pump with a Santoprene diaphragm and EPDM seals to withstand the harshest of alcohol mixes.
Just wish I didn't have to spend $7K on a Supercharger to add this to my Camaro. Friggin Sweet!!!
