[13 FOCUS ST2]

Glad i got the CP-e

My street/comp steeda which I got or 450.00 usually does better then seven degree rise 3rd gear 1900 rpm towards 6400 rpm, 74 degrees out.

How about a negative degree rise. What beats this FMIC deal for performance vs. price value?

Newbie question.

I see that the ambient temperature for the CXR intercooler is higher then the OEM one. Now....correct me if I'm wrong but lower means better right? So does that mean that the CXR core is not even as efficient as the stock one but I'm guessing it matters how the weather was that day as well right?

Ya, ambient temperature depends on the outdoor temperature.

CXr is best bang for the buck IMO

Thanks!

So I guess in many ways stating the ambient temperature is useless since each owner comes from a region or even if they were from the same region the temperature varies from day to day. So the only stats that really matter on that graph is the rise in temperature, weight, and price - right?

Yup pretty much. Well there's pressure drop too due to too big of an IC but...tough to measure

Rule of thumb for intercoolers: bigger is not always better and lower temps don't always equal more power.

Too big of an IC will cause a drop in pressure thus overworking the turbo beyond its efficiency range. You might be seeing lower CAT's but you are losing flow and efficiency.

Most ST owners will never need a core larger than the CXR core because anything beyond that will pretty much be a waste.

But a bigger IC than our current stock IC is still better, but only up to a certain point. I've read through this entire thread last night, gotta say, very informative stuff. From my understanding, the ideal setup for us is a larger FMIC that minimizes loss in pressure while maximizing reductions in CAT's.

I'll always remember what my friend told me years ago that it's not about the length of width of the core itself - it's all about the thickness of the core. Even if a person get's the same size core as our OEM intercooler as long as the aftermarket one is thicker and made better that's all that matters. I don't know if that's true or not but to me it makes sense.

U want more surface are to fresh air and less thickness for best heat dissipation
