Drift-Office : CoBB AP Installed & Tuning in Progress!

[Drift-Office]

Ello All :

Just figured I chime in quickly and briefly about my CoBB experience; it's been pretty good so far and I wanted to show some of the stuff we've been working on and seeing! Let's start off with the basics. Before we go any further, note that all dyno charts are posted in the SAE corrected format, since that seems to be the norm in the domestic markets. (Some others might post up STD ones, but that's just another correction factor that us import guys use, usually yields slightly higher numbers.) That said, here's our baseline of the car when we got it mid December last year...

Car is a stock 6MT.

When we got the AccessPort V3 a couple of weeks ago with the software and reviewing what CoBB had said here about making sure the OARs* were learned, the results were pretty good for an off-the-shelf (OTS) map. This can be done either by driving around and getting into boost or in our case, a couple of pulls on the dyno.

Since we only have 92 Octane here in WA state, I elected to use the Stage 1 Map for 91 as the 93 map would be too aggressive.

^^^ Notice that while the peak HP only reflects about 10WHP (and almost 100#s of TQ) and you'll get a much broader torque and power band globally! To that end, that's not a bad result for not needing to get a "Pro-Tune." The initial flash took about 22 minutes, and each subsequent map (depending on size and changes) took an average of about 3 minutes - so certainly long enough for a bathroom break but not for a cup of coffee!

Having access to the tuning software, we took it a step further and these were the results after about a week on the dyno...

Nice. 309 WHP / 408#s of TQ! Again, peak HP would indicate a 30WHP gain but as you can see in the dyno charts, some parts of the powerband were up 60WHP. And the torque, a staggering 145#s more. OEM boost was about 10PSI, and lit it up and gave it 23-ish PSI. Pretty substantial I'd say! I was pretty eager when I took it off the dyno and drove it around for a couple of days, it felt great having all that additional bottom end...

On a side note, for those of you having seen FI (Force Inducted) dyno charts before, it's pretty clear how the OEM turbo has run out of breath. With it's efficiency maxed out and heat being an issue, an intercooler should be one of the first mods one would consider in the upgrade path, even before an intake. Given what we know, I reckon I'll back down the boost a tad to about 20 - 21 PSI for preservation in our optimized calibration. We'll probably end up a tad below what is represented here but wanted to show you all what the stock setup is certainly capable of.

Note the logs from two back to back runs...

(Charge Air Temp : Yellow Highlighted Line) The first run was @ 155 degrees at the top of redline, while the next run was @ 185 with less than 2 minutes between runs.

But I digress! If there was any question before about CoBB and the EB Mustang - let it be known that it works and works very well at that! Their Mustang AP prices are certainly cheaper than their Subaru ones too!

Regards!

Thank you for the in depth review. It is amazing to see some of the gains from just a tune.

Nice post, I was interested to see how much power could be made on the stock turbo, I wonder how much PSI a stock engine will be able to support reliably.

Where do you feel that the stock turbo begins to fall out of it's efficiency range at, above 20-21 PSI?

This is the big question in my mind too. All these tunes have been making so much additional power, it almost seems too good to be true. Only time will tell if these tuned cars last for 100k+ miles. I know the EB motor has some pretty strong internals but these huge jumps in power still make me nervous a bit.

If you modify any car I wouldn't expect it to last 100K+ miles. Could it? Sure, but if it doesn't you only have one person to blame. Main thing is to take care of your car and don't beat on it all the time if you want it to last, stock or not.

You nailed it. I know a modified car could last 100K+ miles, but you hit on a key point...taking care of it and treating it properly. If you get out and flog a car day in and day out, nothing is going to last very long. However, if you drive it like a sane person with the occasional spirited driving and stay on top of good maintenance practices, then it'll last. I've had cars that lasted well over 100K+ with mods.

This is true to a point, but if a car is tuned too aggressively it won't last regardless of how much you baby it. I guess what I meant was I know cars with Cobb tunes can last a long time. I've seen Subarus with Cobb stage 2 tunes run for over 150k miles, original clutch and everything, before they needed a turbo or clutch replaced (which is about the lifespan for these Subaru components even if they were stock). But those tunes only increased the power by about half as much as these EB tunes do. I trust that Cobb and the other big names wouldn't make an off-the-shelf map that would cause the car to blow up after 50k miles, but with a brand new engine and car, nobody really knows 100% what failures may or may not arise in the next few years as people rack up miles on tuned cars. I know it's a "pay to play" type of situation, maybe I'm just overly cautious. Not trying to derail the thread by the way, I'm really impressed by the gains that Drift-Office has made even over the already impressive Cobb tune.

It's probably already out of it's efficiency range past 18psi. The turbocharger used is tiny, and was designed specifically for high response and a fantastic early torque hit. Not so much for peak hp numbers.

Are you planning anything for the ecoboost? I like your work on the frs.

 

[AVOturboworld]

Definitely!

 

[EcoSnake]

Definitely!

Good news. Glad to see companies that thoroughly track test and abuse their products before selling them on here. Cant wait to see what you come up with for the ecoboost.

Sorry didn't mean to thread jack. Nice work with the protuning. Can't wait until my parts start showing up.

This dinky turbo was built for response, not so much top end. I think for a reliable, long term use - 18 PSI would be I think, beyond it's ideal characteristics. But everyone usually is fascinated by high peak values so people like us tend to push them more than we should. Then again, that's the job of us aftermarkets.

I know the EB motor has some pretty strong internals but these huge jumps in power still make me nervous a bit.

How much boost an engine would take and how much it can hold on a daily basis are two different things. Glory runs in a perfect world environment dyno cell is different from real world. The consensus is that the more power over stock that it makes, the greater the wear and tear. That's an exponential component, and something we can't really quantify as of yet since we're still in the infancy of tuning and the hardware hasn't really even rolled out for the EB platform.

Now if you manage some of the factors in the equation that affect reliability, then you would in theory, mitigate some of the wear and tear. Cooling for one, would be a big plus. I believe CoBB has a pretty cool looking one on the horizon (there's yer plug!) and with all the necessary support mods, we should be able to enjoy our rides for years to come at the very least.

Good news. Glad to see companies that thoroughly track test and abuse their products before selling them on here. Cant wait to see what you come up with for the ecoboost.

Like we did with our other vehicles, we tend to perform all this R&D on our own vehicles before attempting any 'experiments' on our customers' rides. This is how at least for us, have managed not to blow anything up.

Time will tell if they will last for 10k miles at these levels, let alone 100k. The rods look very insufficient if you ask me.

However, excellent results with the tuning. Very impressive.

I think the rods will hold the power we're all around right now, but it'll be interesting to see how far they can be pushed with a big turbo. I'd be more worried about the pistons myself. The Focus ST guys are over 400+ whp on those engines and they're holding together well, so I'd guess the 2.3 would too.
