It's probably not a really fair comparison (in general) as the CAI filter tends to be "tiny" wereas the SRI filter can be a whole lot bigger. The airflow itself would not be the same.
However.....(hear ya)
I have a custom system concept similar to this:

Basically it's a heatshield housing around a filter and you drop a snorkel for cold air pickup.
My "system" also has a bit of ram air effect.
What have I noticed?
With the SRI, pull is a little more decent up to say 160 kph (about 100mph), then the car struggles to pull more. Pretty much like stock.
With my SRI+heatshield+cold air+ram air, I get more pull in the first 3 gears right up to redline than with just my SRI. When I hit 4th, I believe the P5 aerodynamics takes over more and drag rears it's ugly head.
But I still get even more throttle response than with my SRI, and a bit more pull in 5th say after 130 kph up to 180 kph (not greased lightning as I have stock internals). I have yet to do a top speed test.
I have to be careful as anything more than 120 kph and my fuel economy gets worse. I was told that with more cold air, our computers compensate by increasing fuel to the engine. Our cars go full rich apparently around 120 kph.
Nothing here is scientific as our weather has been going up and down lately, and I just switched out of my summer tires.
When a track day comes up, I'll be able to tell you more.
