you want the intercooler that reads 150 psi,,,these coolers are alot thicker so they wont rot out as fast and may last alot longer..i have a ? do you have a pressure relief valve? you may have too much water pressure and may be blowing holes in the coolers

Check out Rtech,

When installed on a boat in exchange of the stock intercooler they were getting more HP. When I put one on my boat with a m4 procharger the FAST ecm & O2 sensors required 15% more fuel, due to the cooler intake charge and increased air flow. Do not know how much HP increase I got but with using 15% more fuel had to be a pretty good increases with only changing the intercooler.

Find tomcat here on the forum or his company R Tech. Hopefully he's still in business, he's got all the intercooler stuff figured out.

I'm getting quotes on finned cupronickel tubing. It's a straightforward job of cutting open the Procharger coolers and fabbing up a CuNi zigzag cooler circuit in them. The finned tubing is expensive, and the box to tube seal is tricky but otherwise no magic.
