i hate to be that guy that derails a thread (ok actually i don't), but there's better physics and math being applied by EE about this whole black intercooler thing. Basically do it if you want the aesthetics of black, but don't assume you're getting better performance because in real terms, you aren't.

But what if you plasti dip it!? Plasti dip fixes everything! That's gotta be more efficient with the rubberized coating help to contain coolness and help cool ther intercooler.
But seriously, more discussion should be had about end tank internal design and flow than the color of an ic.

I agree, I should have stated that the "cooling benefit" they find is not that relevant.
I like my black intercooler, you cannot see it behind my grills.

I bought my intercooler black from the factory. That is all.

Ever race hwy100
Im going tonite as long as it dont rain
Yeah dude are you gonna be down on HWY?
-
I've heard my fair share of HWY 100 stories, but have never been down there. Maybe later this summer... it's not on the top of my to-do list.
Wouldn't mind throwing a few bucks down on roll races though.

Hell yeah BRO!!!

Speed limit is 35, not going to work for your 60 roll haha.
For real though, don't bother coming down to hwy 100. You're not missing anything.

Lol, good to know.

Meth, not even once.
If I ever get a new intercooler I will definitely be applying high emissivity coatings to it. Something to consider if you need to bring temps down without meth/changing the entire intake setup. Some folks have never heard of it before so I thought i'd mention it
Just dont be one of those "paint your intercooler" black dudes
High emissivity coatings? I'd be one of the folks who have never heard of it before. Please explain...
So busy trolling that I missed this.
Emissivity is an objects ability to give off radiant energy (blackbody radiation/heat). The coatings allow greater heat transfer. When used on gas stove burners it is quoted that fuel savings are 5-10% due to the greater thermal efficiency
So its a simple way to improve an intercoolers efficiency
I have my current intercooler painted black but only for aesthetics. I sprayed at an angle to avoid getting paint inside the fins

I was joking about HWY 100. Its not a cool place to be.

Roughly how much power is this thing making now? and how much does it weigh?
I have a dyno appointment scheduled for April 22nd.
Right now, I'd guess 475whp/525wtq and 3300lbs.

Have figured out what your boost target and taper will be?

peak power on this thing is going to be sick. I haven't followed N54 quite as closely in the past 2 years but when I was running an N54, people were capping at like 450 whp on e85 and meth. Now you have upgraded inlet pipes which didn't exist back then, so considering you aren't on meth, but balancing it out with the increase flow from the bigger inlets....yea, I think 475/525 give or take is a pretty realistic number to hit.
like bk335 I am also curious to see the chart. I wonder if the stock turbos hold their breath a bit longer now with the larger inlets ?

Not yet. If this stupid Wisconsin weather would cooperate, I'd be able to get it on the road.

There are a few N54 cars above 500whp now on stock turbos. With inlets and good, non-rattling turbos, they're able to peak at 26psi. Obviously this isn't good for the turbos but those tiny suckers are able to hit it with inlets. I would never daily that much boost through them.
I installed the 3.5 BAR TMAP sensor and plan on targeting around 20psi, but we'll see if my 110k mile turbos will obey commands. I already had problems hitting targets over 18psi last year because my wastegate flappers won't stay shut, lol. Hopefully the inlets, all new vacuum lines, and two new boost solenoids with the 3.5 BAR TMAP will help.
Inlets definetly allow the turbos to hold boost longer, it's one of the main benefits. Everyone says the continued pull past 5500 RPMs is what makes them feel so good.
