The coolers I looked at were for Drag cars in the 1000-1500 horse range. So surely a 125 horse load with a constant supply of cold water would work. The core was about a foot square plus the ends with several layers of cooling fins ( like a radiator) inside. Look on ebay for "air to water intercooler" to see what I mean. They had about a 3/4" fitting for water in and out and either 3" or 3. 5" hose ends for air.
