Have you ever measured the air temp behind the evap cores?  That's what I'm primarily interested in.
 
Thanks,

OK Rusty, just for you (well maybe I'm a little curious too), I found a pocket size data logger, with 7 temp probes. I'll put them before and after both evap cores, oil cooler and intercooler. I just have to find the software and instructions for this thing. Oh yeah, and straighten out all my cooler fins so I can get some airflow.
