Keeping IATs low with inlets with heat reflecting blanket and air scoop - N54Tech.com

seroga1986

I got this idea from a 335 owner that tracks his car and he said it helped alot. This is my own custom 2.5" inlets with a heat reflecting blanket and a cheap air duct/scoop (temp for now). Well after adding this the IATs are about 3 to 8° hotter than ambient on the highway at 60mph. After back to back pulls the temps fall back to the 3 to 8° range real quick. On track last year i had no problems keeping IATs about 15-25° cooler than when i had DCIs with very simular ambient temps. Excuse my temporary cheap air duct/scoop but it sure does help (combined with afe grill scoops) as there is a bunch of bugs/dust/tiny rocks in the filters after a few hundred miles. I am going to make a nicer air duct when im done with my oil cooler project here soon. Hope this help someone and or gives ideas to people.

Apparently the 335D air scoop will route air to that side and should just bolt in!

Super cool dude! I have been thinking in a similar manner! Check out the gold foil heat reflector wrap that is what I wanna use, my under hood is gonna look like a space ship

If it isn't too much trouble do you mind explaining what you used to make inlets and where you sourced k
It? For the price it just seems like a good idea to buy the damn kit...

chatz86 · 03-24-2016, 08:09 PM

Or it could be an older 330d. I think the guys were using a hack saw for the perfect angle. Hope this helps

all youd need in addition are some ram air scoops like the AFE ones

I made my kit right after MMP made their kit so non other kits were out except that and trueform technology. This is a heat reflective blanket not heat wrap or exhaust manifold wrap. They say it works just as well as gold tape but looks better. Remember shiny side down to reflect the heat.

Yeah just buy one of the kits now - it will probably be cheaper but if you are interested i can send you the blueprint of my setup.

Ok thanks and I like the raw look over pretty any day if it work! I'm sure I will become a junior thermodynamicis once I decide to dive into heat management lol

Saw you post this on in one of the Facebook BMW groups.

Love the idea. Can you send me a link to the heat blanket stuff?

Also, for the guy who recommended the 335d air duct... it doesn't fit the 135i. I already tried. I'm sure with some hacking and modification, it would work. But the two scoops don't line up.

You don't want to scoop air in, you want to vent hot air out.

Spend more time in making your FMIC more efficient. No point cooling air that's going to get compressed and heated

neroneuman · 03-25-2016, 11:35 AM

Can you please show how you secured the heat reflective blanket and the routing? Im planning to do this with the 335d air intake

? what about the heat you entrap underneath the blanket? wouldn't that be something to think about

spain4065 · 03-25-2016, 05:26 PM

Just wrap your DP's and wrap your outlets with that gold tape stuff. That would be more efficient and would be beneficial.

I think the thought process with this is if the air sucked in is cooler (with this blanket stuff vs without) from the start... it will either not get as hot or not get as hot as quick (as without it) when the air is "heated and compressed". goal being the intercooler would decrease temps at the same if not a faster rate(again compared to a slightly higher temp w/o these items).

I'm not sure if that's accurate but in simple terms that's how i understood it and make sense to me. I believe this is one of those things where you are looking/hoping to get any little bit of a benefit that you can. Can't hurt right?

neroneuman · 03-25-2016, 09:18 PM

That's right. The cooling capacity of the FMIC is constant even after you upgrade it. But IAT is variable and cooler it is , better it is for the engine.

would this fit the N54 ?

Did it fit?

Beemin · 08-28-2016, 11:20 AM

Yes but you have to shave it down a bit because it's slightly too wide. Easily done and self explanatory when you go to install it. I just used a metal file.

Bmwfixerguy · 08-28-2016, 01:47 PM

I snagged one off a customers car and test fitted it on mine and it worked fine with no mods..
I only used the top part though
My intake air temps at cruising speed where always 12 to 13 over ambient.. When I tested with just the top part of the diesel duct they were 6 to 7 Deg above ambient..
I never logged any pulls back to back but I can assume they would be bettet

Oryx · 08-28-2016, 02:25 PM

I'd be pissed if i took my car into a shop and I found out you were pulling parts off my car to test on your car (assuming you didn't ask permission).
Just sayin'.....

U got a link to the blanket?

seroga1986 · 09-19-2017, 08:10 AM

It was something like this but bigger in size. I dont remember where i ordered mine but i remember it was pricy.

This part isn't available in US. 325/330d never made it here

What car did you take it off?
