By far not an expert, but is your dual pass plumbed correctly. Usually I see the center as the entrance and the ends are the outlets. It really bepends on how the cores were set up. Having the center and one end as outlets could cause you to be pushing water into both ends of the pipe and deadheading th laminova cores. Please correct me if wrong.
Hmmm you could be right, it's genuinely acting like its not connected right. Will check in when I get back home and compare. I followed ZZPs video in stall so I'm fairly sure I have the cores inside setup correctly but the plumbing maybe not.By far not an expert, but is your dual pass plumbed correctly.

Yes exactly my thoughts, its not even just the temp but how it doesn't react as tho it's receiving any cooling even when driving normally after a pull.I’m concerned with the way it doesn’t come back down even out of boost but still driving. See what it comes down to with a steady 5-10 minutes of cruising and not in boost.
yes good suggestions and I think that would help in small ways for sure that add up but I still feel I have a more serious issue and I'm leaning towards the hoses being hooked up wrong possibly but will find out. ThanksQuestion: couldn't quite see, do you have the fan on the DF heat exchanger? It is set up to pull air up through the HE and not pushing down through the HE? One thing to try is taping in a piece of rigid cardboard into the open area directly behind the radiator to close off this space to keep the radiator hot air from escaping under the car and warming the air the HE is pulling from below. Improving the air flow management at the front of the car can help with proper cooling and aerodynamics too. Just trying to think of minor things that could improve your situation. Edit: or install a splitter!
I'm in the middle of my ZZP dual pass install also and I found their install instructions pretty confusing. I had to label mine to try to keep it straight:By far not an expert, but is your dual pass plumbed correctly. Usually I see the center as the entrance and the ends are the outlets.

typically you would try to pump after the heat exchanger and before the intercooler but I'm not sure how much 150? degree will actually shorten the life of the pump.I'm in the middle of my ZZP dual pass install also and I found their install instructions pretty confusing.

So "cool" water enters in the middle, hot water comes out top and bottom. I also wonder about plumbing the pump - it would seem better for pump efficiency and longevity to have it pump "cool" water into the engine rather than pump "hot" water out of the engine. Thoughts??

Of course it depends on the particular pump. It used to be common for people to use a bilge pump as an “upgrade” and those wouldn’t last anytime on the hot side as they were designed for cold water only.The pump portion isn't what fails, it's the electric motor. The motor has nothing to do with the temperature of the coolant, as it's never in contact with it.
It may be good engineering practice to have the pump in contact with cooler water, but functionally I don't see it making a difference here.
I use the frozen boost bildge pump and have not had any issues for a year and a half. Intercooler only on the lnf just doesn't heat that hot. No warranty but so far so good. I do pump from the bottom of the heat exchanger up to the intercooler so the fluid has been cooled to its maximum amount before entering the pump.Of course it depends on the particular pump.
