So I sold my upgraded 14row intercooler and just put a stock on for time being until I buy my new intercooler..
so , on 90' days I'd see avg intake temps of 120-130'F IF I was pushing the car and staying in boost alot. If driven normal it would be 115-120s only..
soooooo this stock intercooler, today temps are crisp 72'F with almost no humidity and just NORMAL DRIVING I was seeing iat's of like 140-150'F . If I did a 0-60 pull only and looked at the temps I SAW 210'F IAT !!!!!!! WOOOOOOOW . YEA , it went back down to 140s pretty soon but that's absolutely TERRIBLE temps. I did how ever see an extra 2lb of boost so I was max boosting now at 22psi I was seeing..
but who started this b.s myth that this stock intercooler is better than most aftermarket intercoolers ??? Lol it wasn't even close to as efficient an ebay oversized intercooler. Sure the boost drop can be debated but if your adding such a larger intercooler that little bit of boost loss for such drastically better cooling COMPLETELY out weighs it..I could feel the power loss too once it got heat soaked...
MYTH MYTH MYTH , STOCK IC IS ABSOLUTELY TRASH !!!!
I can't wait to get that other ic and get it installed, my poor mini 😢 😭 😞 . I know it despises stock , I must do better for it...lol

I was wondering how you got to 22psi? The more psi the more heat right?

absolutely!!!! I'm running a heavily modified engine..
Tpr2 head , ns1 cam , sprintex sc with 60mm pulley and 2% crank , meth and every bolton pretty much possible..
for a stock engine sure stock ic is fins but if your upping to anything over an 11% pulley , just as mini designed the gp intercooler for the higher boost gp , you should absolutely upgrade the intercooler along with a pulley upgrade..
I mean I know I'm cramming alotta extra air through it but for it to give me such higher iat's makes me wonder how many are out there running stock ic with higher boost engines..
anyone running stock ic abd like 17% pulley with the stock SC, could you chime in about your iat's ??? I wonder if mine run hotter because of my sprintex I have spinning to its max..
Lower IATs & less boost - I don't see the advantage since boost equals HP. Are you claiming cooler, denser air more than offsets the loss of boost (2 lbs.)? The S/C, after all, pushes a finite amount of air regardless of the size of the IC. Hence the reason for larger S/Cs and Turbos. And, this is all conjecture unless it's been measured. Butt dynos aren't very reliable. That said, I'm curious and happy to be proved wrong.

wouldn't the increased boost the stock makes be because its smaller and more of a restriction? Soon , very soon I'm going to be doing on track testing..unfortunately it's not a dyno but I can record my data during the pull and see the cars 60ft 0-60mph 1/8mile and 1/4mile tines and compare them..
stock intercooler will be one of the things tested. Also going to testtny dinan throttlebody vs ported stock vs bmw v12 2.5in throttlebody..
I don't think there's any loss of power with a larger ic making 2lb less IF its flowing more air vs the stock..
I see how each has its advantages but on a higher boost engine i can't see a stock ic being nearly as efficient..
I guess track time will tell more because I too don't like to say ones better than the other just because butt dyno and a few generic numbers say so..
the gp intercooler I know if far different than the ebay oversized intercoolers but they made it to function the same way , more surface are for more cooling.. so I think if they went through all the testing they did they found it to be useful enough to put into production...and as time goes on companies have more time to perfect designs and stuff and make things better. Not ALWAYS the case as sometimes they make it just to reproduce and resell but we're discussing performance related nor stock replacement..
I drove it again today with my meth system off and it was high 80s today and within 10min and no hard pulls just normal driving I was seeing 160'F iats and when I had on my oversized I'd only see those temps for seconds after a very long hard pull..
I guess should look at the timing data and see if the car starts pulling timing and how much and at what temps..because your absolutely correct , if it runs the same timing at 100' as it does at 160-200' , though I believe I read somewhere it begins pulling timing once iats reach 100'F but who knows.
but I wonder if an m45 with 17% and full free flow exhaust and big valve head. I wonder if that sc runs cooler or similar temps to what my Sprintex is running it as hard as I am.

I'm running a 17% pulley and a stock intercooler. My IAT's are typically 10-15 degrees F over ambient in summer. I haven't looked at them lately, but that's what they've been in the past. They will climb into the 130's-140's when I'm idling at a drive through or something like that, but they come down withing 5 mins of running in good air flow again.
anyone got dyno overlays instead of butt dyno? I'd be curious about torque delivery and throttle response. Throttle is laggy enough as it is due to dbw.
I made 318 whp on a stock intercooler with 24psi and a rmw head with a aquamist setup on a 90 degree day at sand ridge dyno. max temp was 95 again with m1

checked my temps today running on the highway. For reference it was 113 degrees ambient today… cruising in the highway my iat was 124, max after sitting in traffic and doing a couple of hard pulls was 142.

Thx for the info !!! Those iats were much better than mine..I bet it's my Sprintex that's generating the extra heat being spun on a 60mm pulley and 2% crank. I guess so long as the iat's are within 20' of ambient I consider that very acceptable and with them only spiking to 130s isn't bad at all..
what was your max boost btw ???

What app screen images are those from? Looks very comprehensive while driving with more data at a glance, which appeals vs my OBDLink MX+ app dashboard (2 examples of those PIDs displayed from my Android Nexus 7 tablet)...
^^^ I looked at and considered that app when deciding on an OBD2 dongle. Didn't realize Palmer Performance's DashCommand was that customizable with display configs. It'll work with my dongle (fun word, funnier connotations), so I'll give it a try at some point...
Sooooo major ISSUES running stock ic...
I went on a 14hr round trip , pretty much strait through driving and heres my issue..buuut good news is the car did avg 25.7 mpg..
the stock ic ran usually about 100'-110' degrees warmer than my set speed. So if I was doing 30mph it sat around 130' and at cruising at say 80 it would sit at 180'..
sooo after about 2hr of cruising 75-80mph and still not keeping up with flow of traffic i grabbed my vape out my cup holder.. IT WAS ALL STICKY and leaked it fluid everywhere AND WAS HOT AF ! My whole shifter assemble on the bottom was HOT as well as my cup holders in front and the tunnel when I pressed my hand on it or leg was HOT. It heated up my vape SO much it boiled out the fluid , granted it's a low boil point but this has NEVER happened before in any condition ever !
My oversized ic would NEVER run above 130' cruising at ANY SPEED , EVEN IF I WAS DOING 100MPH SUSTAINED. If I was going up a big hill / coulee or moraine and it was see aaaaaaany boost , like even 2-5lb of boost it would heat up to almost 200' and BS these stocks recovers faster , once back off the hill back just cruising and even coasting IN NUETRAL down the big decent the stock ic took atleast 5min to return back to the 170-180' temps.
I literally could feel the exhaust tunnel radiating heat off of it and it had me so SO SCARED it was going to get so hot it might have burst into flame.. im SO GLAD i fixed and added some extra heat shielding when i installed the coolerworx shifter.. omg omg OMG , absolutely totally not going to be doing any more trips like that until i get another upgraded ic..
I cannot belive you guys run your cars at those temps..I know alot has got to do with my Sprintex and if it's making as much heat as it is , if your running a sprintex YOU NEED to upgrade your ic , they just can't handle it.. atleast how fast I'm spinning mine it can't..
that journey told me everything I need to know now about the stock ic and how it functions on a setup like mine. IT ABSOLUTELY NEEDS TO BE TAKEN OFF, THROWN FAAAAAAR AWAY...
Now , these were temps with bright sun and 80'F outside temperature. At night once it cooled down to 65-70' intake temps only dropped by avg of 10-15' only
lol ,here's my front end once I got back home..

So what’s the best bang for buck intercooler you would say to get ? Once you upgrade to a bigger intercooler don’t you lose the ability to mount the cover back on right ?
fwiw if you dont have the under hood and the divertor on the intercooler it will do this. No idea if you had both on but I have over heated a bone stock car by not having one or the other on

It's almost as if it was engineered to direct air flow properly. I've seen my share of people without those over the years... If you don't like the stock diverter, DDM and others makes replacement ones.

roflmao yeah who would have thunk it But honestly yeah I see lots of people run without and it will cause exact what Adam is describing. I dont bother anymore really. All you can do is put the info out there and let people discern it how they want.
