intercooler question and advice
Need some advice here. I just finished building an airboat with a 5.3 and Vortech supercharger. I am running 10lbs of boost and spraying meth. Now for the question.
My rpms at cruise are about 3000. I pretty much am running in vacuum unless I am running dry ground etc. I did some data logging the past couple of nights and my IAT's at cruise are between 115 and 125 with ambient temps at 85 degrees. When I get into boost and the meth starts spraying temps drop to 115. Ocassionally if increase my cruise rpms to say 4000 or 4500 with out getting into boost my IAT's will get into the 135 to 140 range and then come back down to the 120's when i go back to 3000 rpms. I am thinking those IAT's are a little too high.
I was thinking about taking an air to air intercooler and mounting it on top of engine. Fabricating brackets etc would be no issue. And having it on top of my motor would make a very short run of piping. Do you guys think a standard air to air would get enough airflow on top of motor since obviously it wouldnt be inside an engine compartment etc.
I was looking at this one from Frozen boost.

Open for suggestions and here is a pic of what I have to work with.

Thats what I was thinking. I would leave space underneath it also so you could get air flow through it. I could even fab up a scoop facing forward to force air down through it. Truthfully, we arent talking about a whole lot of money to do this but I needed some reassurance on my thinking. I appreciate everyones imput!
