HPA installed a 5.5L washer-bottle to use for water/methanol storage. It also uses the blend as washer-fluid! Brilliant, however it is kind of a waste so I usually carry "Invisible Glass" wipes in the trunk.

We use a pump/controller setup provided by Labonte Motorsports to inject this into the motor's intake -- providing additional cooling for the air/air intercoolers (twin SMIC's, we are injecting vertically into each cooler to mix with the air flowing in the reverse direction), and a lower intake air-temperature while also raising the fuel's octane to well over 100ron. Special thanks to USRT usrallyteam.com for being HPA's consult on the Water/Meth project!
