Learned a lot from this, thank you 🙏 especially the part about CPI still not being safe when “used just for cooling” because it affects fuel trims. A lot of people were under the impression that it was safe. I’d like to learn more about the water injection as well in the future. 🤟
This was a dope video, I do track days so I may look into getting a heat exchanger. Got my first track day with the stage 2 tune coming up next weekend so gonna track my temps there and see how it does.
I went on BM3 app and saw mine at 133 on a 81 degree day with bms intake. I’m going to buy the extended turbo heat shield and modify the intake to face into the air box and see where it goes
I hear people are using an "interchiller" kit that uses your ac compressor to lower the water temp to -20 to your intercooler. Making your manifold intercooler extremely cold.
Hi there, i am all the way from Recife in Brazil South America, and I really liked your video, very informative and all, thank you for sharing it with us…
Awesome video! Very informative! I wish you would of touched on some of the max/sport cooling settings in the tuning platforms and how it effects IATs. 👍🏼
Please help i ran high iat like 130 and my car makes negative timing on all cylinders sometimes it does that sometimes no.i have downpipe intake and hpfp stage . I switched plugs with all kinds then coils all sensors checked the pump all fluids good but no hope ((even on stock tune
There are two reservoirs behind the front headlight. The smaller light is for the intercooler. Check out my last video walking you through the coolant bleed process for more information.
@@kern417 dang, I was hoping for a few degrees drop or a faster recovery. BTW, the CAC cooling system is shared with the A/C correct? I know that the engine cooling system is separate, I'm just trying to figure which radiator is the CAC. I'm considering on mounting a mister right in front of it to help reduce the IAT. I plan on doing a endurance race and 1/2 mile runs later this year.
Hi Kern, I’m watching this video once again to troubleshoot my IAT temperature (440i GC 2016 MHD stage 1 98oct Ron) the ambient temperature here in Spain is currently 30degress celsius, but IAT while driving is 45-46 degrees celsius… is that normal? if i let the car idling 5 minutes it raises up to 70 degrees celsius… I think this is not normal… i have selected in MHD sport cooling mode for intercooler but looks like is doing nothing! how can i know that the water pump for the intercooler is not working? apparently when i turn off the car, i still hearing a wining noise during several minutes… is that the water pump for the turbo perhaps? i really appreciate your help, thanks!
@@kern417 really? Oh ok, then nothing to be worried about... i’m just learning about this engine and I thought the IAT should be like 5 degrees above the ambient temperature and not almost the double! 😉👌🏻 thanks for your time to help me!
Hi Kern I am having really high temperature in the intercooler, the system was checked, no leakage, tank is full with the green coolant, pump is working fine. I have DP, intake and TU fuel pump, changed the LPFP as well, and did a custom tune which is very safe, around 400 hp, but still when I do a pull on 4th to test it, the temp goes to 150 degrees celcius (302 Farenheit). Could it be a sensor issue? any recommendation will be appreciated! Thanks!
Heat soaking and high IAT in 70-80 degree weather on a stage 2 MHD X3 M40i. What can I do to lower it without making significant mods? Intake modification?
I thought charged air was after it passed through the intercooler, and boosted air was compressed air from the turbine before it hits the intercooler. Is that incorrect?
Is this with the custom tune? Thinking of getting into a m240x, but not a lot of good times posted. How hard is it to get these 1st gen b58 into the low 10’s high 9’s
@@kern417 what about sport for intercooler only? I disabled sport coolant target on MHD cause it was keeping my car out of operating temp under normal driving and didnt affect IAT. Seeing power loss around 100-110 F IAT on a unmodified X3 M40i with a OTS map.

Possibly your best tutorial so far Kev,
I do hope the 🧤 was under the helmet!

Great video!! BTW, where is the intercooler tank reservoir located??

@@kern417 ok, BTW how did your intercooler mixture go? I'm considering distilled water with a addicive like water wetter by redline
It was a very slight improvement. Not really a game changer

When you're not moving there's no air flow so it's normal for iats to rise. As soon as you start moving again it should drop pretty much immediately.
How can I add ice to my B58?

Same thing same mods have you found the solution?
Hello. I've saw your post on some forum. How much °C did you gain by removing the engine cover?
maybe 1-2
If you upgrade the intercooler do you have to add more coolant
It will increase the coolant system volume, yes.
My car has been feeling MUCH slower on these hotter days. Kinda a let down lol

Charged air temps refers to pre-intercooler
Any draggy times with the new turbo kit?
Current best is 7.2 60-130
Is this with the custom tune? Thinking of getting into a m240x, but not a lot of good times posted. How hard is it to get these 1st gen b58 into the low 10’s high 9’s
Yes it is a custom tune. All you need is a turbo and upgraded Fueling
@@kern417 0-60?
Guruuuu
Im only stage 2 but should i turn on sport cooling on mhd just cause?
I don't recommend it for daily driving
@@kern417 I just had the same question, why do you not recommend it?
@@Dennis0908 Because it drops engine temps below optimal. It should only be used if you're at risk of overwhelming the cooling system.
@@kern417 what about sport for intercooler only? I disabled sport coolant target on MHD cause it was keeping my car out of operating temp under normal driving and didnt affect IAT. Seeing power loss around 100-110 F IAT on a unmodified X3 M40i with a OTS map.
Methanol will extremely help in reducing the IAT and added octane.
You missed all the cons involved with wmi
Did you watch the video? Like at all?
