Thinking about changing stock intercooler, but not sure if it really makes sense.
Could not find any valuable comparison of products available on market with OEM.

So I did some research about options available on market for bk2 and made some comparison:

Stock
Dimension: 600mm x 170mm x 100mm
Frontal area: 10.2 dm^2 | 100%
Volume: 10.2 dm^3 | 100%
HP: 330 | 100.00% - I've read several times that stock is good up to 300whp, so lets say it is 330hp
CFM: 420 | 100% - don't remember where I've got this number

845 Motorsports - largest volume, highest declared HP, the largest one that fits stock place
Dimensions: 710mm x 200mm x 100mm
Frontal area: 14.2 dm^2 | 139% of stock
Volume: 14.2 dm^3 | 139% of stock
HP: 600 | 181% of stock
CFM: unknown

Tredstone / TR8 - highest declared CFM, the most closest in size to stock and at the same time declares up to 500HP
Dimensions: 560mm x 200mm x 90mm
Frontal area: 11.2 dm^2 | 110% of stock
Volume: 10.1 dm^3 | 99% of stock
HP: 500 | 151% of stock
CFM: 750 | 178% of stock

CP-E / HYCK00002B - requires crash bar modification
Dimensions: 610mm x 241mm x 83mm
Frontal area: 14.7 dm^2 | 144% of stock
Volume: 12.2 dm^3 | 120% of stock
HP: unknown
CFM: unknown

turboXS - largest frontal area, requires crash bar modification
Dimensions: 597mm x 254mm x 89mm
Frontal area: 15.2 dm^2 | 149% of stock
Volume: 13.5 dm^3 | 132% of stock
HP: unknown
CFM: unknown

as for me it looks like either stock intercooler is underrated or some manufacturers provides wrong numbers like HP

Intercoolers don't "add" power, it increases the potential for the engine to make power.

How does it do this? By cooling air coming from the turbo (turbos get hot)

So what you want to look for is volume, cooling efficiency, duration of efficiency (will explain), how much pressure has it been tested for, and flow restriction.


Volume of air the heat exchanger portion can contain. Larger contributes to turbo lag.

Efficiency - With ambient air temps and outside air flow as a constant; at X temp of input air, how much has the temp dropped coming out of the other end.

Duration of efficiency - How long can it maintain that efficiency until it degrade (until it heat soaks). Guess construction can go into this as bar and plate type are less likely to heat soak, but when they do, take longer for it to cool down. Tube and fin have the opposite issue.

Well, i know how intercooler works in general.
I just wonder how the hell Tredstone TR8 which is nearby the same in size to stock, declares up to 50% more potential HP.
I believe that all intercoolers are made by the same (or nearby) technology which should provide (nearby) the same numbers in potential HP for example.

It's marketing and nobody bothers to test it.

As I said before, intercoolers don't add power.
If it did, then window home AC units would have 1 hp coming from a half hp motor; and your car would have 350 hp because it has 5 heat exchangers running on the same principle (radiator, condenser, evaporator, intercooler, heater core)

It's the same marketing crap that they do with air filters. If an air filter is advertised to "give" 5 hp, then theoretically, running no filter will give you more.... It doesn't work like that.

What he said^^^^^. T kits.com's Fmic is specifically jigged, dyno tested, flow tested. For their kit and turbo assortments. That is how it should be.

The horsepower/tune begets the need for a larger , blah blah fmic. Not the other way around.
