Did a data log and my IATs were killing me in the quarter. After 3 runs on a hot day I was 140 deg to start and ending at 160+ degrees. Once my inter-cooler water was hot, it stayed there. I added a fan to my heat exchanger and can leave my pump on with the fan to cool the inter-cooler water. In about 3 minutes I can get my IATs down to 109 degrees to start and end up about 125ish. This is was on a 90+ degree day.
Now I need to get back to the track and see if I can get into the 12s.

How much timing are you losing with the intake temps being so high? I know on my stock tune on my 4.8 it was pulling 11 degrees at 122 degrees IAT. I can only imagine what you are losing.....
I second the Ice bath, that is probably the best thing with WTA intercoolers, 50 degree intake temps while it's 90 degrees outside, just awesome....

Broke into the 12's
Ran a couple of weeks ago and hit the 12's.
Ran 12.955 @ 105.06. DA was 4751 and Relative Density was 86.82%.
Still running 10 lbs of boost with the stock cam.
Today I ordered some of the parts for the DOD delete in preparation for a cam swap. Still need head gaskets and head bolts. I think I am going with Cometic and ARP. Unless someone has a better idea.

New track time
One year later one second faster. Who knows maybe next year a 10.9.
11.95 @ 113.75
1.78 60'
6000 DA at RMR in SLC
I'll upload a pic and a video later if it turns out.
