The air temps all depend on boost, outside temp, IC, and flow.... IF there is a ton of restictions then the temps go up... Now I do not know the self ignite point of gasoline but 275 should be getting damm close, that engine should have had all kinds of detenation going on..

Please advise.

I'm looking for a good reliable kit to use w/ my Radix.

More info please! Pics etc. Are you using the truck's AC system?

My system uses an insulated 2.5 gallon water tank. I fabricated the tank from 1/8" aluminum - to fit nicely above my rear crossmember and under the bottom of the cab. Other than the two 3/4" hose nipples on the tank - there is no access (or need for any). I use a SHURflo 2.8 gallon per minute water pump. My pump is mounted on top of my transmission crossmember, so it also fits under the cab.
I fabricated the intercooler to work with this chilled water system. It's basically 12 rows of finned tubing that's been boxed to make the charge air run over/thru it. On either side is a very basic "box" that water is plumbed to and from. In this system the inlet side"box" pressurizes all 12 tubes equally, so each tube is filled with water that's only allowed a single pass thru the tubes before it's chilled again. The box on the other side collects the used water.
Another use for this chilled water is cooling my fuel rails. The chilled fuel allows me to run extra timing even while in boost and also balances the fuel temperatures between cylinders/injectors. I tested the chilled fuel rail system before going to the turbo system and it made an astonishing 14 rwhp and 24 rwtq difference even then! Now it's even more critical. My guess would be that the additional cooling of the fuel and the allowed additional timing would be in the 40 to 50 rwhp range.
The intercooler fluid route is: 2.5 gallon tank to water pump to heater core to air/water intercooler to the fuel rails and back to tank. With the additional radiator in the ice chest - I can chill the entire system down to about 40° in about 5 minutes worth of circulating. Since the tank is insulated, it stays nice and cold while I wait for my turn in the staging lanes. Since the system can be cooled down so quickly it makes it perfect for those rare instances when I manage to go rounds while bracket racing.

Instead of using engine heated water to heat the air, we're using A/C cooled air to chill the water. I leave the pump on continuously so I'm making COLD water the entire time I'm driving it. I live in AZ so I run my A/C system year around.

Dude, that setup kicks *** man! Good job! What kind of truck is that BTW? I know on NBS trucks the AC clutch disengauges under WOT, does yours?
Next time I go to phoenix I want to see this thing.
I'd like to know how you cool the rails too? Also does this make the AC blow hotter in the cab? What are the coldest IAT's you've see, and with how much boost?
