Default retsell's HUGE radix heat exchanger

Here are some pics of my massive heat exchanger, keep in mind it goes all the way to the bottom of the bumper.




I will find the ones with the grill on the truck tomorrow.

The other day when driving in 70 degree weather they were 85 (normal driving) under hard acceleration up to 130 mph they got up to 128.

CDT???

I did not replace the pump, it moves enough although I am sure it could be better...

Compressor Discharge Temp, i.e. (after the S/C rotors/intercooler).

The IAT sensor is after the rotors. Part of the radix kit comes with an IAT sensor in the lower tub after the intercooler. You cut the wires for the IAT in the MAF and hook them to the new sensor.

Autotap, that's where I got the MPH from since the speedo only goes to 110

Autotap is god.

also it would be cool to have an IAT sensor prior to the intake/blower and compare the temps.

Yeah, I wonder if I could hook that up to something else... or rather, put a button inside that would kick a relay that would momentarily switch back to the MAF sensor reading so you could get an idea. That may throw off the computer though.
