Option B with flowthrough tank vs expansion tank
As the title suggests if you were to setup Option B as GM reccomends (expansion tank), it would bleed air well but not really increase your coolant capacity. If you kept the bleed line but placed the tank in series of the coolant loop, would it bleed just as well?
If anyone runs such a setup and can post some IAT1 and IAT2 after a long pull that would be great

Here's a little clip from the GMR Stage 3 kit:
What’s the purpose of the second surge tank?
The second surge tank is for the aftercooler. Without it, it is very difficult to purge the air from the system. Using the additional surge tank ensures a fully purged system with no trapped air. This higher pressure system will provide an added level of efficiency for the intercooler system.
The Opt. B setup does add more coolant to the system, but it will not be used like it would be in a flow throw setup.
I've been running the Opt. B setup for 3 years now, and it has worked great. I have never used a flow through tank myself, but some members have found that it helps.

I would like to know really how much of a difference we are talking here with an actual flow through verses the standard GM Opt. B.. For some reason I can't see it making much of a difference.. I'm not sure why.

What's the difference. A radiator does not have a constant flowing system.. And it is perfectly efficient seeing as how the motor doesn't overheat and it cools parts that are running a high duty cycle at all times. You are not in heavy boost 100% of the time. I believe with option b, a FMHE, and dual pass you are about efficient as you're going to notice.

the flow through tank increases the system capacity and thus its thermal storage capacity. it takes many more btus to raise the temperature of 5 gallons of fluid than of 1 gallon so by having a big storage tank you can ensure that the intercooler itself has cool fluid running through it for the entire pull. the next level is of course active intercooling, where you push the temp of the fluid below ambient using the ac system as a chiller. for most applications option b and dual pass are enough, for more aggressive setups a fmhe or griffin are fine but for top end stuff you need to break out next level ideas like the flow through tank and active intercooling

Option B takes care of air entrainment in the coolant. With air in the coolant, the laminova cores cannot transfer heat from the inlet air charge to the cooling system efficiently, as the cores require contact with water, not air bubbles.
take out the air bubbles as option b does very well, then the system cools efficiently, which makes option B do A LOT for cooling; lower IAT2 numbers are the proof.

that statement is so wrong. For a guy like you who does good work and is smart its a surprising statement. Here is why your statement is wrong. The stock OEM h/e cooling system does not self bleed air.

if you talked to Gloria you are set. i was on the road picking up parts in NY state and doing shipping stuff.
front mounted h/e are cheeap. Chiwanese, not always cores designed for heat exchanging. not always dual pass. look at the thread zoomer did on his core versus the others with cutaways.
partially block radiator assembly.
do not benefit from the air damn positioning
or the cooling fans.
is that enough?
race griffin. is best.
if you read the zzp thread zoomer said something like " the stock oem h.e is very good just not enough of it" or words to that effect.
so race griffin .
