MAP Street Intercooler & now Race Intercooler Torture Tests

[TheLion]

3rd gear pull 3000 rpm to redline MAP Street core is looking pretty good

Looks great, I wouldn't change it unless you start pushing a lot more power through the EB. However, we do have the answer to our question about how this compares to the levels, given they are at the same price point.

Neodark's 3rd gear pull ended at about 85F, looks like yours ended at about 90F and was still on a rising slope. Ambient was at about 65F. Neodarks 3rd gear pull with the levels doesn't give his ambient, however his sig is for Forida, in July, I think his ambients were probably in the 85~90F range, but ended with a flat charge temp slope and at a slightly lower temp of about 85F.

But I would expect the Levels to perform better, it's monstrous compared to stage 1 units. 980 in^3 vs 600 in^3. Unless the flow rate is horribly tuned for the stock trubo, the significant surface area advantage should net a notable gain.

At 6000 RPM your charge temps look to be about 85F. I'm going to assume an 80F ambient for Florida which is probably a bit low just in case it was at night / evening for neodarks.

MAP: 85F-65F = 20F temp rise

Levels Street: 85F-80F = 5F temp rise

There's a notable difference in rise over ambient. This also falls in line with what Nick Levels stated he was seeing from his customers of about only a 5F to 10F rise above ambient on his Street IC's (depending on how modded the engine was).

BTW according to this, the average temp in Melbourne, Florida on the day neodark posted was 92F: http://www.accuweather.com/en/us/melbourne-fl/32901/july-weather/332282

An air to air exchanger cannot drop the temp below ambient, so he must have done the pull in the evening. Low was 75F, so if it was the coolest of that day 85F-75F = 10F temp rise. Still 10F cooler. Higher loads should produce even more of a difference as the added cooling capacity will become more apparent.

Sorry I've been away for a while, life and work have a way of doing that.

First I'd like to thank Adam [MENTION=13414]MAPerformance[/MENTION] for getting me the hook up on a brand spanking new Race IC to test.

The IC arrived extremely well packaged and suffered no damage during it's journey to Germany.

Honestly, Install is even easier than the Street Ic but you absolutely have to remove the front bumper and crash bar (which are no big deal really) I was worried about t when I installed my street IC but it tuned out to be really simple and straightforward.



There is a reason that all of the hard parts on my car come from MAP, Sure they may be a bit more expensive than some of the competition but all of their stuff is top notch quality fabbed by them in house, on both intercoolers, the quality of welds and end tanks are second to none. The race IC mounts directly to the rails on the front of the car making installation child's play once the old one and air diverters are out of the way.

The street core is dwarfed in height and thickness, the outlet of the Race core is sized the same as the throttle body meaning you cant use the OEM hose like you can for the street but MAP includes a shiny new Hard pipe and t-bolt clamps for everything. It looks nicer and performs better but is getting me a bit further from the "I'm Stock" look I was going for. I will be powdercoating that pipe black as well.

While I had the car in the air I changed the engine and transmission oil to Royal purple HPS 10w40 for the engine and synchromax for the gearbox.
When using Mobil 1 full synthetic, my catch can looked like this every 600 odd miles

8000 hard miles on Royal purple later, this is all I got.

Looked and felt good enough to put back in, As I've noticed, the blowby on these ecoboosts smell like they have alot of fuel in it. That maybe a harmless byproduct of direct injection as the oil that came out of the pan was clean and did not smell of fuel at all, alleviating any concerns I had.

I was a bit rushed on the installation as the shop was near closing time ant though I assured them I would finish in time the were not happy to see me stopping to take pictures. so I stopped.

Data logs and impressions next

 

[Glenn G]

So Here is a 3-4 pull I did on the Stock Intake, Map street IC, Flat foot shifting
Ambient was 63.7 F, intake temps started at 66.4F dropping to Ambient during the run.
Charge Air temps Started at 81.9F dropping to a low of 77.5F before climbing to a max of 86.7, 23F above ambient. Max vehicle speed was 95.6 mph Max Boost was 24.6psi tapering down to 21.5 at redline.

Map Street for the wifes I believe is still the current lead pony. Whenever that day comes.

 

[Glenn G]

This Run with The Race IC was done Under similar conditions except it was almost 4 deg warmer, (67.3 degrees) and My MAP CAI was back from the Powdercoaters so I put it back on.
Intake temps Started at 72.6 dropping to Ambient over the run, Charge air temps started at a toasty 92.8 from city driving quickly dropping to a low of 83.4 before climbing to a max of 87.8F or only 20.5 above ambient. Boost max was 24.54 psi dropping to 20.74 at redline.
You can see I started to lift to shift before I remembered I have FFS. That has to be one of my favorite things about the Cobb AP.

As I suspected, the race core heats up much faster than the Race core in traffic, though it drops quickly while moving, The street core Drops temps only slightly slower.

The Race core does gain temp slower while in boost and keeps the temps lower longer, I believe peak temp would be 10 or less degrees lower than the street core.

There is a very slight amount of extra lag added by the volume of the core, noticeable to me but not too bad. These are not knocks against the Race core, it just shows how good the street core actually is.

The MAP street core is a stout little guy huh?

 

[Glenn G]

I decide to beat on it like I stole it

71 rising to 74 degrees Ambient, the MAP CAI drops to 2 degrees below ambient which is awesome, the heat rejecting powdercoat having some to do with it I imagine.
I get up to 145mph before I let off to compare nicely with the run I did on the fist page of this thread.

The race intercooler definitely rose a bit slower than the street and peaked 2 degrees below it. On the top end I really didn't notice much difference and the data seems to concur.

My Verdict is that the MAP race or other similar sized intercoolers are only really going to shine with a turbo upgrade, on the stock turbo, the benefits are there but small. I believe that it would hold up better to long track sessions but my Autobahn blasts have shown that for a street car it does not make a huge difference. If I had to do again I would stick with the street IC because of the stock nature of it's mounting keeping the car far more OEM looking.

MAP did such a good Job with the Street core, they just didn't leave alot of room for improvement.

Certainly at Autobahn speeds and continuous airflow being directed over the core I would expect the overall results to be somewhat similar as you've pointed out.

I think where the larger IC will show its true merit is in stop and go traffic, and like you mentioned racing conditions. The thermal properties of the larger IC would allow it to shed the heat in the CAT's quicker in those extreme environments. Thanks for your review!

How's your CP-E unit performing compared to the map street?

How's your CP-E unit performing compared to the map street?

I've only had the CP-E Delta Core and stock core. There's no comparison between the two. Hands down the CP-E out performs the stock unit. The CP-E will experience an initial temperature drop when it becomes fully pressurized and then will very slowly start to increase in temps during the course of a run. It recovers very quickly and allows multiple back too back runs without experiencing heat soak. It only heat soaks on the hottest days with a lot of stop and go driving, but I've never seen it get over about 135F. It normally sits at about 10-12 degrees above ambient temps.

The factory unit does not have the initial temperature drop as it only rapidly increases charge temps and it takes a considerable amount of steady state driving at 70+ mph to get it to cool back down. It normally stays about 15-20 above ambient during normal drive conditions.

Sorry to go off topic Glenn. Carry on.

no You are good, It is on topic and my data shows exactly the same thing, the temperature drop on the race core as it pressurises is more pronounced than it is on the street core but it exists for all cores. The temperature climb is slower and recovery is also faster like you said.
Honestly what caught me by surprise was that temperature stability for both cores was within 2 degrees and I was expecting ~ 5-10.

I think we will find this with all the larger cores the advantage will be in long term endurance, not in anything you will see on the street or even the autobahn

 

[gtmorgan23]

So are you staying with the street or the race?

 

[PRG3k]

Pretty much what I expected from MAP. The MAP street performs very similarly to the $900 FFTEC/Garrett core I just put on. In my opinion it's one of the finest pieces of aftermarket stuff available for the Ecoboost. I'll actually be sad when it's sold. I kind of like looking at it.

Thanks for this comparison, Glenn

Where's the sales ad?

 

[PRG3k]

Haven't yet. Putting my screen name on a piece of paper and taking another picture is a step that I have not come to LOL
