This thread is a good one bc we can re-validate current technology against older tech
discussed in previous threads and determine if something new or better is out for our use
Trends change and so does automotive technology

Telling people to search is for the super simple questions where nothing new will be learned.
In Hulk's defense he was just talking smack bc I poked the bear on newbs inability to search... I take full responsibility

I noticed the meth knocked about 30F off of my IAT's but the biggest difference was the car felt like it was holding more timing driving daily...
I am running Snow performance, Safe Injection combined with VC-25 to control boost injection starting at 5psi and full injection at 10psi. I am using the washer tank as a reservoir and normal behind the fender pump location. With about 90% water / 10 % meth through a DO3 pre-charger / post intercooler (flat pad with a 90* DO nozzle holder) DO7 I was able to drop temps considerably.
Old No meth setup 2-3-4 to 5500rpms = 180* or more IATs / 65-70* outside / 75-80* starting IAT
New with meth 2-3-4 to 5500rpms =135-140* about IATs / 68-72* outside / 86-90* starting IAT
I also gained between 1PSI-1.5PSI of boost with the DO3 Pre-SC
I used to see 12.5-13.X PSI pre-meth install with 185mm/LTH combo... but the DO3 pre-SC I now see over 14PSI in 3rd-4th before the belt slips some
I am stepping up to a DO10 next time the charger comes off and will be adding the thermal gaskets I have as well to isolate the SC/IC from metal on metal contact with the motor.
Everyone saying they are taking a few degrees of less cabin cooling with their killer chiller is what will keep from doing it
Anything over 85-90* outside in the Carolina humidity and the AC just starts to not work and takes a while to cool the car down. :-/
Meth is damn amazing on these cars, if you can do it.... do it!

Nothing new to learn, unless someone has updated the intercoolers in this car that I am not aware of. Feel free to trial and error what has already been solved. As they say, "A smart person learns from his mistakes, a wise person learns from others'."

0-180mph with ambient temps @ 87-ish degrees.
Iced 2.5 gallon tank started @ 64 degree IAT'S. Finished with 104 degree IAT'S passed the 1 mile mark. This is done with Meth/Water injection and with "updated intercoolers". lol
The magic is in that box. (new version) I also changed the meth/water injection to a new set up that stops my IAT'S from climbing and even dropping IAT's during WOT after above recorded data log was done. Not a bullsh*t 1/4 mile run, mind you......a mile. Something to think about? I can run a total of 28 gph of nozzles without soaking/fooling IAT sensor. Keep drinking the cool-aid, folks. Nothing to see here.
Screw it. This is my updated version. The trick is what is inside the tubes, though. (Laminar Flow) If you decide to grow some ***** and build it? PM me and I will show you the rest once you show proof of your progress and at least $250 donation to American Veterans/Battered Families/Local Children's Fund
I mean EVERYTHING. From meth/water injection to what and how to cut pieces. Also show you what to use and where to buy. Ball is in your court now...

I call dibs on your old set!
Bad @$$ trendsetter yes you are!
Congrats on the tire roasting setup
is that over or under 15gph worth of meth nozzles Erebus?
***re-read it.... holy gonzo 28gph ehhhh ****
Now I am not scared about stepping up to a DO10 post IC from a DO7 with my 185mm CP. The DO3 pre SC is just sealing the rotors some. I am in the small pad post factory IC so I think there is enough distance between the nozzle and the temp sensor to fully mist and not soak it

Be sure to get some *concrete* numbers before and after. I have the parts to split my system but frankly I'm not convinced it will matter. I'll probably do it and run a before/after test. If you could do the same we can corroborate/contradict each other.
Let's agree on some sort of a test routine.
I don't exactly have a 0-150mph facility available to me...

At this point I doubt I'll split the system. The KC is keeping IATs in the mid-50's, even when the outside temp is in the mid-80's. I'll have more numbers this weekend at the track when I use the drag valve to route 100% of the refrigerant to the KC.
However, for the sake of being scientific, here are my thoughts on doing a proper before/after test of a split cooling system:
You will need to plan a route that you can drive consistently. Ideally a country backroad that has some uphill parts, some downhill, and a lot of flat terrain, without having to get stuck behind traffic. I would set cruise control to a certain MPH and let the car take care of the acceleration. Add in a couple spots where you can floor it and have a few seconds of boost. Run the route once before splitting the system, then run it again the same day (or at least on a day at the same temp) after you split the system. Make sure to run a logger the whole time, capturing IAT and Boost at a minimum.
That should produce two graphs that can be compared apples-to-apples.
The outside is, I guess? Frozen Boost doesn't make them, though. Let China make it for you for $68 and swap out the core with an efficient intercooler core. The difference? 6 degrees cooler while cruising (summer temps + heat soak) and a 8 second delay in IAT rise during WOT. Is it worth it? Depends, I guess. If everyday driving involves an occasional run against a Prius? Go for China. Spending $210 on parts and $100 on labor for better twin intercooler cores is still cheaper than drinks with friends at a sports bar. (AA is for quiters)
Did you try flipping the surge tanks from left to right? It would remove the straight pipe sections and make more room.
Can't do it. Why?
1) hood clearance with taller part of surge tanks (if reversed?)
2) laminar flow (restriction to larger volume is not good...if reversed?)
3) air flow is a stange thing (like women, it needs a moment to collect itself)

Your test isn't very correct and having people think there iat drop so much.I wanna see no meth and do the same pulls
My test? Very correct? Thats a data log from a mile event race, sugarplum. A data log that shows a system set-up that can control IAT climb better than any snake oil product that companies attempt to sell for our M113K.

Having people thinking what? With the statement that I now use even more meth/water to drop my iat's below ambient? I'm not selling anything, mr slow 55. Nor do I give a rat's a** on your take from my post. Just sharing information on something that I promised I would from over a year ago.

What? Pound sand, brah. Shove your request where the sun doesn't shine. Keep doing whatever you feel is best. lol.

I agree. Would be interesting to see a pull with and without the meth spraying to see how much of a gain the intercoolers are doing on their own.
When i spray it drops temps to ambient but around the 4550rpm mark it starts to rise. So I'm going to go up a nozzle and have another crack. Also mounting in a second IAT probe into the surge tank, for my ndash to see if i am 'tricking' my sensor or not.
