I lol'd when he said step-function doesn't apply to Intercoolers. Killed his entire argument.

I doubt that is the case.
From the EQT website about the Vortex "You can also see that the Intake Air Temperature barely moves through the entire pull. This shows how efficient the turbo is at these boost/power levels."

This is what happens when one purposefully tries to sound smarter than he actually is.

Different situation, EQT Vortex isn't a modified housing. It's designed after an IS38, but doesn't just re-use the housing and stuff in better internals. And that's also balancing the internals size to housing... instead of just sticking in the biggest chra that fits.
Also from the EQT website: "The housings are modeled after the OEM IS20/IS38 turbochargers for proper fitment, but they are all brand new and original castings made and machined for the specific wheels we use. "
It doesn't seem that the EQT housing is substantially different, other than EQT machining their replica of the IS20/38 housing.
Kind of getting off track with that, so what you're saying is that the high temperature from hybrids doesn't apply to EQT? Are there certain hybrids that have been identified as causing high temps?

They are dimensionally different. Set them side by side with an oem turbo.

Not saying it wouldn't apply to a vortex, pushed beyond a certain point any turbo will get hot and cause runaway temps. But it's a very well balanced turbo that has proven potential of ~550+ while outspooling similar "hybrids" w/o drawbacks. The EQT isn't a cast replica of an IS38, it's a completely different turbo... that's why the EQT site says "modeled" after. Like @Diggs24 said if you put them side by side, there are noticeable physical differences, especially with a Vortex XL. I'm pretty sure Ed would've put a bigger wheel in there if he could've without drawbacks.

Yup, the reference eqt is using about it being modeled after the factory housing Is in respects to it bolting up to the head vs a true full frame option needing a custom adapter/manifold.

horsepower and motorsports is for sure non linear also. just think about rpm as one example, rev a stock motor car to 7,500rpm and probably would be fine, rev it to 8,000rpm and you probably blow it up. there is some small incremental point at which the motor is fine and then more than that is catastrophic. I'm sure heat soak with intercoolers has a slower but similar dynamic where at a certain point stuffing more heat into it just overwhelms its ability to absorb and shed heat and it starts getting hot very quickly, you see this issue with pikes peak cars a lot since the air is so thin and less dense that cooling issues become immediately very severe, and your brakes can light on fire and you can dive off a cliff into a ball of flaming ruin

I spend 2 hours on the internet googling it. Let me make a blog about my expertise.

HIS DATA DOESN'T LIE, BUY STONKS NOW
Yeah it's kinda pointless. A bigger turbo setup running more boost will have higher temps and a greater air mass flow-- both of which put greater strain on the intercooler and you'd expect higher IATs. Intercooler performance has so many variables it's hard to get real accurate data or comparisons. The best we can probably realistically do amongst ourselves is maybe compare 60-130 runs, IAT rise for a given setup etc.
