Looking to add a .3 nozzle in the location provided by Vortech on the volute and spray prior to the cooler. The path is about 7.5 inches and I will run 75% meth. There is an aluminum core inside the cooler and I am concerned the meth may slowely eat at the aluminum. Should I worry or not ? I am guessing the temp at the Volute is in the 200deg F range.
