The attached link describes the authors testing of several intercooler pumps individually and running two or three of them in series. (For Shawn: I think you should run your new pump in series after your existing pump)
Lingenfelter also ran some tests comparing different pumps that was also enlightening.
Given the info on the two links and the tests that I have done to improve my IAT/IAT2 temps, I don't know if anyone here is desperate enough to drop $550 for the Stewart-EMP intercooler pump reprogrammed for higher pump output. I wish I had known putting two pumps in series was an acceptable option cause there was absolutely nothing wrong with my Bosch pump that I upgraded to the Meziere 20GPM pump. Given that I now have the Super Chiller this is a mute point for me, but I wanted to share this data with the forum.
The only info I can't seem to find is the pressure data for our motors. I assume given the fittings we use its somewhere between 1-4PSI with the Bosch pump and 1-6PSI with the Meziere and Jabsco pumps. My only tests were with the car idling between Dyno runs and the Meziere pump was twice as efficient as the Bosch one which is consistent with the LPE graph at low pressure.
