Say 3 different engines all 1500hp.
One large motor, low boost...clearly it will need lots of flow, but limited cooling ability. a 3" open tube might suffice. It will flow well, but obviously do no cooling.
medium sized motor, moderate boost....clearly it needs flow and cooling, an open tube would never suffice
small motor, high boost, it still needs lots of flow, but also will need a lot of cooling ability
Ignoring the above, the general consensus everywhere is that Garrett cores seem to do everything well. They flow superbly despite high fin density and because of that high fin density they cool superbly.

Ok, so a 416ci motor, with a F1A that seems to make a nice linear boost to 10psi, then falls off as the rpms climb, like the intercooler is backing up and holding back flow. Instead of seeing 18-19psi, I only saw 16 at redline. My iat's aren't bad, they only went up ~10 degrees on a pull thanks to meth injection into the blower, as well as post intercooler.

I'm not saying I have the answers.
Obviously the more boost generated, the more heat is generated. That's fairly universal. So for a centri there is probably a slight advantage there given boost patterns compared to say a fast spooling turbo setup
However if you've a very restrictive core there may be a lot more boost created than you're actually seeing.
Also IMO you'd need to monitor temps without the meth affecting any readings to get any sort of idea if you're current core is working well in that respect
Clearly if you're relying on meth for a lot of cooling, you could concentrate on a core that flows well, so a cheaper unit with more open tubes might suffice.
But even with my really shitty double core unit at around 2.75" thick I made 13 years ago when I first fitted the LS to my car with the YSI ( was 2 old cores from a twin turbo setup with a previous engine )
I measured no noticeable restriction across this double core, there was no boost drop...but it also didnt cool very well.
They were fairly open tube/fin design, fin density inside would have been very low. But it was essentially free so I didnt care at the time
Really to get the full picture of your own setup, you'd need to test boost before/after the core, and charge temps before/after the core.
Both of those should still be valid despite the meth injection as long as the after core temp sensor is prior to any further meth injection

Run pipes to gauges, watch gauges whilst driving. Or video them.
Job done.
Just test the gauges before using so you know they do actually read the same, I've a few cheap gauges here that read miles apart !
If you wanted to get fancier you could opt for a pressure differential gauge or sensor

Buy 2 cheap identical pressure gauges. Some simple push fit pneumatic fittings. Drill/tap each end tank or pipework near the core itself.

I know this a old thread but I think I might have a similar issue with my intercooler. I have a D1X Procharger installed on a forged 6.2 with PRC 225 heads and Holley high ram. I just dynoed this set up at 15psi with 16 degrees timing it only made 700rwhp on 93 and dual alky. It’s seems this is a bit low on power through a 6 speed. Only possible weak point I can think of is the Treadstone TRV25 intercooler I have installed. You guys think this could be the issue?

Could be the tuner, the setup, the dyno, belt slip, whatever.
