How has your experience been with PWR radiator so far?
I'm about to order the same one. I don't need triple pass. Do you have the intercooler also?

At this time I don't see a need for the triple pass (although I fully believe it's more effective) as I've not had excessively high ECTs. Last year with just the PWR track spec radiator, HEL oil cooler, and the Acuity reverse flow hoses I was usually peaking around 215-220°F, and if I ran the interior heat it would bring it back down. This was with the stock FMIC.

This year, so far, with the PRL FMIC, I've been in the same range. At TNiA for the one session I was able to do I was running 210°F or under with the same cooling setup listed above, PRL FMIC, and @siwelnosaj 's cooling plate in ~75°F ambient (which was the first event trying the cooling plate out), but I haven't had the current cooling setup + the PRL FMIC in summer heat yet, although I'm sure that's coming.

All temps above were also still with the factory hood vent rain guard in place. I should add, I did put about a bottle (12oz) of water wetter in when I installed everything (the rest of the coolant is factory Honda 50/50 coolant) - theoretically that's helping too, although not sure how much.

That's good info and a solid temp range for coolant. What ambient temps have you been running in? The event I will be testing at in 10 days should be in the 80s, possibly low 90s. I'm curious to see how the full package reacts.

I didn't get my FL5 until mid-summer last year, and didn't have it on track until the fall, so I don't think it's been on-track above 80-85°F yet. Since I'm in Nashville it definitely gets hotter than that, as we will touch close to 100°F in the summer with moderate-to-high humidity, so I very well may run into an issue, I just haven't so far.

Based on the long range forecast, Road Atlanta next weekend looks like it may be in the mid-80's °F, so that will be the hottest I've had the car out in with the current setup.

I should add, I did put about a bottle (12oz) of water wetter in when I installed everything (the rest of the coolant is factory Honda 50/50 coolant) - theoretically that's helping too, although not sure how much - I figure if I can get ~3-4°F (or more) each from a few different things (Acuity hoses, your cooling plate, water wetter, hood vent cover removed which I haven't tried yet, etc) it can add up to a noticeable improvement, but we'll see.

That's reasonable. My plan is to run pwr intercooler, radiator probably get HKS oil cooler because I love the cut out bumper idea. Might try the cooling plate and run as much e85 as I can. Waiting on the mugen hood coming this winter.
I'm not a track rat so hopefully my plan works.
