Fiesta ST Intercooler Info Thread

I say just get an ATP fmic and call it a day. great core and decently priced.

I don't think they are much larger than the FiST FMIC.

I am pretty sure the FoST IC is larger, but I can't find FiST dimensions to compare. FoST IC info pulled from FocusST.org.

Stock FoST IC
Core Dimensions:
26" x 6.25" x 2.5"
Core Volume:
406.25 in?

Compared to the Cobb unit-
Cobb
Core Dimensions:
27.5" x 6" x 3"
Core Volume:
495 in?

Mathematically based off of Cobb's statements, I'm assuming the FiST IC is somewhere around 315-325 in? and would place the FoST IC in-between the two. Considering the fact that it's only ~$100 brand-new from Ford and can probably be had used for less from the FoST community, it would be an inexpensive alternative for someone that doesn't need 'maximum' cooling and had no intention of going big-turbo.

Of course, my math could be totally wrong based on my assumption of the FiST's stock IC measurements, and that could make the FoST IC either a better or worse deal for the cost.

If its free... It worth it, lol

Well, just by counting cooling rows, the FoST one is larger. 10 rows to FiST's 8.

I'll go measure my OEM FiST fmic at some point today, it's just sitting in the garage.

Cool thanks, now I don't have to walk out to my garage.

We should sticky this stuff somewhere.

Hmm... But what about the mounting points? I'm sure the silicone pipes won't mind the 1/2" move but mounting might be the problem.

If its free... It worth it, lol

If you're measurements are correct then it's still a huge value even if bought new from Ford.

Focus ST intercooler part number
CV6Z-6K775-A
MSRP $138.63
Tasca has it for $91.50

That's awesome

Ok I just went out and measured my OEM FiST intercooler.

Core is 27.5 x 5.25 x 2
Top mounting points are 32" apart
Widest point, being the outlets are 40" apart

So your measurements where a little off.

The FoST mounting points are very different so that might make an install slightly more difficult. Also the extra .25 in height over the cobb unit might make it a very tight fit. I know my AIRTEC makes use of pretty much all vertical space and it's a tight fit. I wish I measured my AIRTEC before I installed it.

I was just fixing to post they were not down to the MM, lol. Measured it quick on the car, next to a 26x15x4.5 I have around the house.

So using dyn085's format:


Stock FiST IC
Core Dimensions:
27.5" x 5.25" x 2"
Core Volume:
288.75 in

Stock FoST IC
Core Dimensions:
26" x 6.25" x 2.5"
Core Volume:
406.25 in
33.8129% difference over OEM FiST IC

Cobb IC
Core Dimensions:
27.5" x 6" x 3"
Core Volume:
495 in
52.6316% difference over OEM FiST IC
19.6949% difference over OEM FoST IC
5.6075% difference over ATP IC

ATP IC
Core Dimensions:
24" x 6.5" x 3"
Core Volume:
468 in
47.3736% difference over OEM FiST IC
14.1264% difference over OEM FoST IC

 

[Sourskittle]

So 30% increase in volume for free to $100? Wow... That is pretty good for a stock turbo car... Plus.. Dealership would prob never realize it = warranty

I started another thread in this section and will be adding all the tech info of different IC's.

So far the Mishimoto J-Line is the king

[rodmoe]

And I think I sticky that one without reding this one LOL

 

[HaveBlue83]

it's all about core design and flow. I'm set on the ATP.

 

[Kip2MyLou]

Is it worth getting the charge pipes from cobb? Are they really necessary immediately if an intercooler is in the immediate future? Or is it okay to run the intercooler with stock pipes? I'm asking because I would save that cash and invest in their intake when it comes out.

 

[rodmoe]

On the stock turbo the factory charge pipes will be just fine ..

 

[Kip2MyLou]

Sweet. Thanks man. You just saved me some cash to put toward my intake and downpipe.
