How much power can you put through these on a daily driver? Or would this be variable pending waterflow?

 

Yes, its variable pending waterflow and water temp

 

Well assuming the stock aftercooler with a small heat exchanger in the front and a small tank somewhere, probably 400ish for normal use. With a bigger heat exchanger and larger tank or even iced water you can run a lot of power through it. I dont have a pic i can link now but a friend built a custom ice chiller for his Vortech that uses a fuel chiller from Moroso and runs the liquid through the lines made for fuel which passes through a coil submerged in ice/water. It works extremely well...
