So I have been reading a lot about inetrcoolers on the forums and have a question. What would I (the car actually) see performance wise by installing a larger intercooler? Not an intercooler and a tune, or catback. or anything else? Just a larger intercooler?

You'll primarily see lower charge temps and less heatsoak if you run the car hard on the track, especially on a hot day.

I did exactly that. I had purchased an after market intercooler for my 15 Ecoboost but the car was totaled before i could install it. Do the first mod to my 17 was to install the intercooler. I realized a noticeable increase in power over 5500 rpm.

i know the feeling...i can say from the layman's pov. i became convinced the aftermarket Street-size IC would benefit me and made the purchase...when i saw the stock IC next to new CVF street on the front lawn, i felt a little embarrassed for Ford...and i just knew, inherently, that i did the right thing, even tho i still didn't fully understand or couldn't explain why.

So 0-5500 RPM was unchanged with a larger IC?

It shouldn’t increase power, Itl keep the power always there. A stock pull will feel same as a aftermarket pull,

but if they do another pull immediately, the stock will start to gimp power.
The aftermarket should pull, pull and pull again.

I could see a benefit though power wise in hot climates for DD. Lower charge temps all around, while stock would be cooked just driving not even being aspirated

I have Cpe fmic and I am glad I did. All the pulls always feel lively, vs one nice pull then instant slug

That is what i always thought but any intercooler upgrade i have done in the past was always with a tune until my 17.

My 17 was the first time i installed an aftermarket intercooler on an otherwise bone stock car. Whether it was more favorable charge temps or increased flow it definitely had increased power on the first pull and every one after that in the upper rpm range.

It’s possible due to your climate your car was already close to heat soaking just from regular driving.

simeone in a hotenvironment would notice the largest increase

Yes, this is exactly why I installed a much larger aftermarket intercooler on my otherwise stock engine. I do HPDE events with the car, and the engine was losing power at about 5200 RPM. With the larger intercooler, it pulls strong to around 6000. I don't believe I'm making any more horsepower than stock, but now I have all the stock horsepower available for the entire lap, for the entire 30 min session.

On a related note, revving the engine consistently to 6K during HPDE events has caused engine oil temp issues. I'll be installing the Mishimoto oil cooler this week. Hopefully that will resolve it.
