There doesn't seem to be any concrete evidence that to support either. "come on look at it "is pretty much the same thing as "its not the problem". At least i offer some speculation as to why i don't think its good for high flow. Every time fluid changes direction it loses speed, air leaves the SC to meet a practically flat face where it makes a 90 degree turn then it has to make a 70 ish* turn down then a 90 to enter the cores then another 90 as it leaves the cores to head up to the runners then another 90ish* into the head... i just don't see how no one finds that to be an issue.
I'll shut up once i see some flow numbers.
I'm not saying anything, i'm simply questing it.

its more from the lsa change the lift and duration is helping but not nearly as much as you think or as it should be helping
there is not complete solid but like i said the manifold has been 450 or more with a snail and who said ill post up the numbers it may just be pics
thats the truth

how do you know? !
Ultimate flow through the LSJ manifold is one thing (0.2mm fins with 0.3mm in between, so effectively 60% open space over the core length), but I need more cooling capacity!!
Running above 90°C on closed circuit track days and like to get that down to 50°C.
More cooling surface > less air flowspeed over the cores > increased cooling capacity & less resistance. Win win win...
(Water meth injection is just a bandaid for this and no E85 here.)

Do not run methanol then
Get the car on a dyno and figure out at which point you begin losing power by only running distilled water
Jetting sizes are now available in .25 and .50 increments for more precise sizing

according to the man here Boostec Us, Inc. richard i believe is his name the cores are not really designed for specific hp level. the problem we have is complete system design we do not have enough coolant capacity in the system and that it needs to be increased
Showing my face here again for the first time since having a Lysholm 1600 from back in the day.. Area is right.. the stock intake mani is useless and will kill it.. 1600 was useless on the LSJ.. car was best with the TVS 1320 on it
Well, Laminova advices max 2.5mm fin-core per HP(crank), so with our 4x180mm cores they are flat maxed out @ ~290HP 
And water injection is already in, but it's not helping that much (need bigger nozzles) and really a pita to keep filling up the waterbottle on the track...

I found that 60% meth worked the best on my LNF
