"COLD" air intakes??????

I guess I should have said that boost is more linear in most supercharger applications. Typically you don't see max boost at low(er) rpm like a turbo (no donkey kick, which is in itself a byproduct of lag). This is especially true for centrifugal superchargers. Boost increases at or near the same rate as rpm. There are exceptions though, depending on the type of supercharger. I've seen dual supercharger and turbo/supercharger combinations that work on even different principles.

So to get back on topic, the question is.... why am I seeing the same charge temps between an open element (FSWERKs) and isolated (Cobb) intake systems?

I did notice that my IATs dropped when I pulled the fire resistant pad off the hood. It probably helps with airflow over the engine.

Because the charge temp is read after the air passes through the intercooler and apparently your intercooler is doing its job good enough to keep the charge temps at that temp range. Also, if you are on a hwy when taking those measurements and not stopped, the air inside the engine bay isn't much different than the outside air.

Just going to throw this here and run.

I should note they showed a cold air did absolutely nothing for a GTR. Ultimately, it's down to the platform, I think. Plus, as many have already said, the FMIC is going to be a bigger impact on a turbo than any cone filter.

Not highway driving. Just around town... even in light traffic.

It's definitely dependent on the platform. NA engines are a lot more susceptible to intake changes, whether positive or negative when compared to OEM, due to the reliance on atmospheric pressure and a lack of intercooling ability. It's part of why they lose so much performance with altitude compared to FI.

Oddly though, FiST members keep bringing up their DA when they're not happy with their numbers...

Tl;dr-Not apples to apples for the sake of this discussion.
