Watching the gauges for charge air temp, ambient, and IAT seem to point to an adequately sized intercooler. I hope this holds up as the weather gets warmer, too. FWIW, we've had a couple days around 80 deg F, and there isn't any evidence of heat soaking the IC. This might be the first stock turbo car I've ever owned that enjoys this!

If you watch the various dyno videos, you'll see very consistent runs. The guys at Edmund's also pointed this out. Almost every car faces a heat issue on the dyno, so this is very encouraging. It bodes well for track days in the summer!

That aside, I could see a bigger intercooler, but it's not a priority for me now. For those that have it, do you have instrumented changes for before and after?

While I'm happy with the stock intercooler, that isn't to say there isn't room for improvement!

I don't expect to jam a significantly bigger IC, but I would like a more efficient unit (less pressure drop)!

Mountune makes just the unit and this is something I'd like to test in the near future.

Just borrow Daves (D1JL) when he is not looking . I thought he put one on a while ago..

Right! At our upcoming track day!

On a serious note, I know these units are good. I have some data logged reference points, and would like to do a back-to-back comparison. I have no doubts this is a meaningful upgrade.

Don't you think I might notice?

Let's see how fast you are without an IC! No, I won't plug it -- "run" with a massive leak!

Cobb Surgeline is 5 miles from my house. When I get some time I'm going to schedule some dyno pulls and post them up!
McRib-I wasn't saying we wouldn't benefit from a bigger intercooler, I was just noticing how the Fist has much better flow to it than the FoST.

Right on, we're on the same page. I expect a nominal gain under normal use, but better "resistance to loss" under severe loads. We'll see.

Mountune offers this in black powdercoat, and I decided it would go nicely with my car's black theme!

Since this has to be OE quality for warranty purposes, they powdercoat all of them. Here in CA, it doesn't matter very much!

I took some comparison shots -- the core is modestly bigger and the construction is of obviously superior quality.

Early on, I'm seeing a pretty big difference in intake temperatures! It's almost always a few degrees over ambient and cools faster under airflow.

Hopefully this means I won't have heatsoak issues under any condition!

Once you get the front fascia off, it's a pretty easy job. If you're being careful, it will take a couple hours to install. I'm very happy with it and recommend it wholeheartedly!

Edit: fixed typo

So am I missing something?
Did you buy this?

Oh, right, yep and installed!

 

[McRib 1s Back]

The real question is, would you notice? Is there enough performance difference that you'd be able to easily tell?

Since I drive around with my AP always on, the numbers are actually quite different. I've done some before and after datalogging and will do more today. The weather conditions are the same. Conservatively it's consistently several degrees cooler. It takes a lot to bring it meaningfully higher than ambient -- even then it cools right off.

Your point remains valid -- you won't feel it until the heat gets to a point where it affects power. That takes a lot on this little car!

It could my imagination but seeing the cooler intake temps makes me feel like it used to feel when driving in the cooler evenings.

Nice
In for numbers

Okay, here's one sample:

Ambient 72 deg F, 15 minutes of spirited driving, stock OE intercooler would allow intake temp to spike to 91 deg F.

Same cycle and conditions with Mountune IC peaked at 82 deg F, it took longer to get there, and was around 78 for the most part. It also cooled back to 75 once out of boost and moving at 30MPH.

Both running the 91 Cobb map on the same 91 octane fuel. Repeatable runs in my local industrial park loop.

Knock count was zero for both and -1 OAR-L. No apparent loss of power on either.

Maybe the photos don't show it well, but they look so close in size that I don't understand how the Mountune unit can perform any better. What am I missing?

Much less drop in pressure! Also I'd say around10% bigger core.

 

[McRib 1s Back]

Was there any drifting involved?

Dave

Yes! Jam in, drop throttle, slide, get pointed the right way and stand on the accelerator. Rinse, repeat.

Also...I'm experimenting with lower air pressure to gain better mechanical grip from the tires.

"Before shot" while getting the FiST aligned over at WestEnd Alignment, note the visible IC:

"After shot" with new stealthier IC!

So did you map out the spot for the two hook while you had the nose off your car?

Dave

Eh, kinda...

I want a clean setup and have some ideas. Stay tuned!
