Josh, what exactly do you want to know? Do you have something specific or just want to know if it works? I can answer whatever you want.
To get to the your point....yes J2 mod works and you can not flow the fluid through the intercooler fast enough. The faster the flow the better the heat transfer. I'm at an honest 16GPM at my return line and if I could figure out a way to make that 50GPM I would do it. I have done everything I can (within reason) to optimize fluid flow. My tank looks like a whirlpool when I turn my pump on.
The benefit of the J2 mod over just having more volume with a trunk tank alone can be seen in the datalogs. I have been racing and logging my car for a long time with a trunk mounted tank (and ice at the track) and I always saw my IAT2's raise like 50-60* during a single pass (80*-130+), now my temps rise like 20* with no ice and even less with ice. Depending on how hard you are spinning your blower, some people actually see a drop in temps across a dyno pull or pass at the track. Ask Allen about his old 2.8H KB setup, his temps used to drop on a pass.......so like start at 100* and end at 95*. It's hard to believe but it's true.
Justins setup has been proven on a lot of cars, I was skeptical at first but I'm very happy I did it. You just have to get past the mentality that you are flowing the fluid too fast.
EDIT........just read your post above this. I agree our IC core is small and the airflow path is terrible as the intake air has to make an 'S' to even get into the combustion chamber. However the size of the lower intake dictates that and there is nothing we can cost effectively do about it.
