    Default Intercooler question / quality of water in parker / lhc

    Would like to have some opinions on inter cooler core selection vs where you do a lot of boating at.

    It seems that the water in Parker and Havasu has more of an alkalie than other bodies of water and I have seen what this does to aluminum heads and an fittings when you don't drain your engine. So would you be better of choosing a cupernickle or an aluminum core, and how durable (longevity/ years) can you expect from each being in fresh mountain water vs Parker or LHC?

    If you have a choice Cooper N is always better for corrosion resistance and heat dissipation. The thing is that Cooper N is heavy and $$$$ and also not available for some common cooler housings. We actually epoxy a ZINK on the Intercooler end caps to prolong the cores from corrosion of any type. Here is a pic of an old twin turbo core that lasted 20 plus years!!👍Click image for larger version.

    Tim, after 110 hours running on Lake Havasu I pulled the motor out of my Datona and the XRP hose ends on my Whipple inter cooler were so corroded they actually broke off when I tried to disconnect them. Concerned that the inter cooler may have been corroded, or flow restricted, I blew air through it and found no signs of any restriction or leaks. I was surprised given the water fittings were practically corroded shut. Based on my experience I would say the cupernickle inter cooler would easily out live the aluminum ones, at least on Lake Havasu.

    Yes, it is amazing what a high Alkaline fresh water can eat up! After a Colorado River Trip, some flushing would help. 👍

    What effects does this alkalinity have on steel ? This might answer some questions of corrosion on my heads.

    I suggest draining the block and heads after every trip out. It is real easy to do and is way better for the motor parts...
