Direct Port Meth Injection HSF-4
Extracting maximum power from our Stage 2 Supercharger with 11:0 compression requires serious detonation resistance that 93 octane pump gas simply can’t provide on its own. As a result, we did a direct methanol injection system that has one nozzle on each intake runner on the lower intake manifold plus a seventh nozzle in the intercooler inlet. By injecting water/methanol directly at the ports, the intake ports and valves are kept cooler, thereby transferring less heat to the incoming air as it is ingested. Not only is the intake air charge as cool as possible, but the water/methanol injection’s octane boosting properties gives this setup the detonation resistance it needs to make monster torque and solid power reliably and consistently.
