Default FTRA or similar question

Has anyone noticed if their car runs any hotter with one of the ram air kits that use a box that goes under the lid? Reason I ask is because it looks like half of the radiator is blocked from airflow. Thanks.

They do block a good portion of the radiator and that's one of the main reasons why I'm not a big fan of those types of ram air set ups, though I highly doubt it causes that much more heat.
I have the free ram air (FRA) mod and I feel it does nearly as good a job (same?) performance wise yet does not block the radiator.

I had this same concern about the SLP CAI (and saw
it raise my IATs over the stock SS hood) so I hacked
it up and made something I think is better.

Down in Florida I need all the airflow I can get, to make
my "160" 'stat stay satisfied. Under load the rolling airflow
is not really enough to cool both the radiator and the A/C
condenser. Let alone with any serious obstruction. On my
rig I already had the tranny cooler mounted and the CAI
wanted to sit right over it, pretty much blocking the center
1/2 - 2/3 of the radiator in the direction of flow.

I hacked off all but the last 2" or so before the plate,
and cobbled on my own ducting. This draws air from
above, rather than below the plastic divider panel
that ducts the chin spoiler air to the radiator. The
nose space of the car is fairly open. I also relieved
the foam behind the "nostrils" on my SS so that there
is easy airflow through them, into this nose space.
So it's not entirely ducted, but it is well fed with
cool outside air and well protected from road splash
and armadillos (super sucked up what?).

It's nigh impossible to get a good picture of, being
pretty much obscured by the upper sheet metal,
otherwise I would post the thing up.

But IATs are back down to about ambient (vs 10+F
rise from the CAI, if you let it heat-soak) I was seeing.
Radiator shrouding is minimal with the majority of the
duct removed.
