Anybody using on top of the Phase 2 kit, all of this installed by a Ford dealer with warranty? I'm not concerned with any race classing, just for your typical HPDE and track days. I want to keep my factory warranty for now, need the CARB cert. Any inputs, performance, reliability, temp maint, warranty claims, thanks!!
I know that their warranty 3/36000 is applied to your 'in service' date, not the SC install date, correct me if I'm wrong.

I don't know anyone that has firsthand experience with this cooling kit. It sounds like a step in the right direction, but
my opinion is it's still not enough to meet all the demands of road course conditions. Roush claims "+28% Engine Cooling Capacity" which helps but doesn't match the +60% more horsepower (heat) you'll be making. And "+22% Supercharger Cooling Capacity"?...
Knowing what their baseline is I think that'll still prove to be insufficient on a road course too.
IMO the intercooler in the manifold is the weakest link and needs more coolant flow to be very much more effective. This added cooling kit still retains 3/4" plumbing throughout. I doubt that
any amount of added auxiliary cooler capacity will allow the intercooler to effectively extract
enough heat through 3/4" plumbing. The theoretical best case scenario is if the heat exchangers could reduce intercooler coolant to ambient temp. I'm sure this kit helps get closer to that, but, ambient coolant restricted to 3/4" flow rates will not keep up with 20min. of repeated WOT boost demands.
No one likes to hear this and I had to learn the hard way myself. It's no easy or inexpensive task to increase flow but there's no other way to get an intercooler that is dimensionally limited by the manifold to effectively cool better. Increasing pump capacity will only help a little and quickly reaches a limit with diminishing returns. It takes swapping
every component for ones with larger ports, and all the associated plumbing to get a significant gain in flow and more sustainable cooling.
That being said, I've run my 3/4" intercooler system on track and it will work, to some extent. Beware of engine temps and know that you'll start off with the 750hp you paid for but heat soak will take over quickly, IAT2 will rise and the engine will pull timing in self-defense. You will end your session far short of 750hp.
