Very much so. This is the big boy rule pump and 1.5" lines. The lines have an unrestricted path to and from the ice tank. There are no flow issues. I generally see a 10-20* increase in similar sized setups. This is with ice water.
We saw a 75* increase in IAT this weekend on less than 15lbs. Cooler was 51ish on the hit and peaked around 125* Ambient was around 80*
interesting that you were able to cool to 30* BELOW ambient before the pass. Nothing I do can get temps below ambient prior to a pass like that. It will get down to ambient, maybe a couple * less but nothing like what you're seeing.

Yeah I'm not sure why that is. This cooler was ice cold to the touch in the staging lanes. I'm pretty sure inverted is flipping on the pump one minute before his burn out, I cant remember exactly. Maybe he will chime in with his process. Also I drain his tank to damn near empty before the ice goes in. His ice tank will hold about 20lbs of ice.

Perhaps turbo placement, turbo air intake, etc are playing a role here ? And perhaps even sensor type and placement.

Yes we empty the tank with a small amount of water and pack some ice in. I leave the pump off until right before the burnout and it stays on until after the pull..
This previous data was on low boost but ignition issues. Tonight we will be heading back out for more accurate data. no pre cooler temps available yet.
My buddies 2000 hp chiseled a2w gained 10 degree over ambient here at LS fest in Vegas. 100 degrees air 110 intake air temp at the 1/4 24 psi from a s485.
Just a totally side rail thought and I'm rusty on this,, but if you take the pounds of fuel & the BTU per lb, and the lb of water in the system, should be able to make a table of how many seconds of power you have for your ice load.
Any heat exchanger (Intercooler) has a peak efficiency point with a given flow in the media on each side o the exchanger.. at a static flow rate on the water side, if you measure the delta-T (temp) its pure physics after that.. Unfortunately thats kinda hard on a car which is so dynamic.
These guys provide a significant amount of the cooling for all the over the road trucks in the US, there are a couple other brands that are less common that get used as well. But they just have some interesting thoughts on cooling systems. http://www.evanscoolant.com/products...mance-coolant/

Evans does not cool as well as water, it does not transfer heat as well...and as they like it run straight, there would be no means of chilling their fluid easily.
For water/air systems that cannot cool the water via the A/C or other means, then packing it with some form of ice is the best option.
Oh I wasn't saying use it for the intercooler,, sorry ,, I just was pointing out that in their tech stuff there is some interesting things about liquid cooling.
The fact that it doesn't flash to steam, and shrinks instead of expanding when at freezing makes it safer. I use it on my 4x4 so I have no pressure in the system, the Evans runs the same temp as the 50/50 (Thermostat is the same) but I don't see the heat surge after a hill climb.. But that's not the problem here.. I'm just throwing out some thoughts, hope constructive..
/\ Real quick, maybe I missed it, what is your pump and line size setup?

Well Folks, the temps are finally well under control.
In the midst of all the back and forth that had gone on with the old intercooler, Ron Shearer of Shearer Fabrications reached out to me. After several discussions with him, evaluating my data, expressing my concerns to him that I still had a lingering glimmer of a doubt in my mind that my outlet temps and/or combo were indeed the cause of my issues, he assured me that my temps are absolutely normal and he was beyond confident his 1700hp cooler would keep the temps at bay. Having reached a complete and total dead end with 417 I pulled the trigger. It was on the way.
Upon receiving it I was extremely pleased with the quality of the new unit. One thing to note on the installation of the Shearer Fab cooler; it is COMPLETE. No additional $300 water manifolds to add on and additional $80 fittings required to get it plumbed. I took my -16 lines and plugged em in. Fabbed up my new cold pipe and got it fired up.
Unfortunately the next month had no open track rentals available and most everything I would be doing was street cruising. I got the car up to Ocean City hotrod weekend and cruised in the brutal heat we had the first couple days. Just glancing at the deltas between pre-cooler and post cooler temps while driving with ambient temp water I could already tell... This is already performing significantly better... But I am a hard data guy, I gotta get to the track.
(still pulling air from behind the radiator)
Fast forward a few weeks and I was finally able to make it to a local test n tune. This would be tricky due to increased heat soak on the motor and intake manifold itself from sitting in staging lane lines, as well as the fact that it was 11* hotter than when I did the 417 testing. Still gonna send it!
The following datalog comparison is running the EXACT same boost/tune up on both intercoolers. The ONLY difference between the 2 passes is the intercooler. This is the same 5 gallon ice tank, 20lbs of ice, -16 lines and EMP water pump as before. Like I said before, it was considerably hotter outside as we're getting closer to summer now and the 417 runs were done in the very early spring. 71* ambient, 1100da with the 417 unit, and 82* and 2040da with the Shearer Fab.
Enough talk. Data:
Again, this is the exact same tuneup. Dotted Line is the 417 cooler run, Solid line is the Shearer Fab unit. In Red is my pre-cooler sensor, which you see maxes out at virtually the exact same time in the run, and the Green is my post cooler temps.
The car is going through the traps more than 70* cooler in the 1/4 and 60* cooler in the 1/8th, despite running on a hotter day. The rise during the run has been more than CUT IN 1/2!!! That directly = added horsepower throughout the ENTIRE pass.
One last thing as a sidenote that I found interesting in comparison was how the temps are affected in the burnout. Just so happens both burnouts were nearly identical in length, pre-cooler temp and boost, roughly 3psi through the burnout.
As you can see during the burnout:
417: 24* rise
Shearer Fab: 6* DROP.
Take that for what it's worth.
Another thing to take note of is the car on this night was 4140 lbs, just shy of 200lbs heavier than when I had the interior removed while shooting for best ETs early in the spring. The car trapped 148mph with both coolers, despite the added weight when I ran the Shearer... She's gotta be making more power right? This was also confirmed in the datalog with fuel consumption increasing with the new cooler.
Sorry for the long winded post, but I am finally very pleased with the combo and have finally put this to bed. I cannot thank Ron enough for a truly well performing product and stand up customer service when I had questions and concerns. It has been a pleasure doing business with him!!! I also want to thank Sam at Direct Performance Solutions for his ongoing support!
