I have seen a few in operation , When I wanted to install 2 SUPER COOLERS on my boat 2 years ago I went looking for some kits and the only ones I could find were used ones that had inter cooler core issues , so I would have had to make new custom cores built rework my fuel lines and throttle cables. I ended up building custom cores to fit the carb boxes that I was already using .

You are right, my one kit had a inner leak in the core, funny it was used on a fresh water lake . Im having a spare made and I had pu another. A core is 500.00 then labor to remove the tanks and re-weld them. Did you run upgraded mech pump or 12v?

I converted mine to run aeromotive marine a100 electric pumps and I added two stage water pumps to feed the intercooler

I'm building a procharged 383 now . actually motor is done just figuring out all pulleys and still need to rig and make oil lines .I just came across threads of the rtech cooler and looks awesome .any of these still around ?

Tom stopped making the super cooler about 12 years ago but when i was looking for some kits 2 years ago all the ones I found had inter cooler core problems

if cores can be replaced i know an awesome welder at Cobb in Texas .i will try to do some searching
