I haven’t had time to post in here so lets back up a bit
starting with this one here. Your close to being accurate but I must point out a few other points.
you would have been better off google-ing the words i used and you did not understand than proving to everyone that you don’t understand.
I will however attempt to explain it to you in detail.
Fluids such as liquids and gasses cannot support a static shear stress. This is what makes the fluids. Solid things can withstand stress in the shearing direction.
Viscosity is the time rate of shear strain. It is a measure of how quickly a fluid will move to avoid the shearing stress. For example molasses has a high viscocity, if you put a stick in it it will SLOWLY fall over. Water has less viscosity, and the stick will fall over faster. Air has way less viscosity, but it does still exist.
Knowing this we can begin to talk about laminar flow, velocity distribution, and the boundary layer.
Are you aware that the oxygen molecule attached to the side of the inter cooler will not detach from the metal until the air reaches a supersonic velocity?
This is called the “boundry layer”. In a laminar flow, with a subsonic velocity, the velocity of the fluid at the wall of the intercooler is zero. The velocity in the center of the tube is the maximum. The distribution is parabolic. As shown below:
Normal to flow in rectangular section:
Perpendicular to flow:
You will note that in a laminar flow (laminar means not turbulent) , the air in the center of the tube NEVER touches the sides of the intercooler, and therefore will transfer no heat. That hot air just goes right down the tube and comes out the other side. No heat is exchanged.
Now in the TURBULENT flow depicted above, the air is swirling around and each air molecule will come in contact with the walls. That molecule will then transfer heat to the wall when in direct contact. This is how an intercooler WORKS. This is what it is supposed to do.
Turbulators force the airflow to be turbulent. They literally disturb the air, making it NOT laminar, so that it does exchange heat with the walls.
See all these little fins INSIDE the intercoolers flow channels? They are turbulators. Look it up. Garrett spends a lot of time and money optimizing the density and design of turbulators so that they can get the maximum heat transfer with the lowest associated pressure drop.
The turbulators not only prevent laminar flow, they also act as additional surface area for haet to be shed into, and as conductors transfering that heat to the EXTERNAL fins, which then transfer that heat to the outside air.

this is true, I did not argue this at all. Read my earlier post again

NO! this is not the correct term. Not all intercoolers have turbulators, and from the picture above you cannot tell if they are present.
The turbulators not only prevent laminar flow, they also act as additional surface area for haet to be shed into, and as conductors transfering that heat to the EXTERNAL fins, which then transfer that heat to the outside air.
I did not argue this. The point that I have been trying to make is that turbulators, while increasing the heat transfer have a negative effect of restricting flow. It is a trade off and you cannot simply state that that a intercooler with turbulators are better.
Here is a question for you.
Are you considering all internal fins to be “turbulators?”
hey MAFDARK, im not gonna quote a mile long post, but you said INCREASE YOUR SPOOL TIME… now wouldnt you mean DECREASE the spool time.
less piping = less lag in theory. which would be a decrease in the time its taking.
Bigger core = more time to pressurize?
if the entire system is efficient it should make a marginal difference
It was a guess. 
you were hoping to increase efficiency and make more power on lower boost, but you used the same intercooler core??
you can see some more pics of tony1’s quality intercooler core here:

At a price of 1125 dollars no doubt it isnt the most affordable on the market, but note this intercooler is the high end intercooler in the honda market, and it supports 850+whp. mainly marketed towards sfwd drag cars where not only does it have to perform, but it has to look good, and have a name behind it, these guys all want sponsors, and a consistent car.
yours looks like a jhonny race car intercooler with some end tanks. it comes in more affordable but that is the only advantage you have in this comparison.
what size core is on yours? and what brand is it?
im not sure what you expected from this thread? everyone to agree that because yours was cheaper it wasnt worth getting the more expensive one?
there are middle of the road high quality intercoolers for street cars that wont break the bank. you can pick up a good quality intercooler for $350-400 that utilizes a garrett core to support 400-700whp.
Calling out Tony 1 LOL!
Not Really, Greddy 3/4 row was $1900 new.
Porsche M.S. 993 GT2 intercoolers made with Secan cores were in the sub 15K range when the chassis what being raced extensively. I’ve heard that TK has made a few for 996 Turbo customers in the 20K range. I know the cores are rediculously expensive.
Sure why not? The physics of nozzles, diffusers, and loss coefficients apply to the entire system which if I’m not mistaken, includes core tanks.
It probably is the best mass produced intercooler out there on the market and I’m not doubting or calling out that by any means. Could have been thrown through CFD and works well for what he see fits. However there are always areas for improvement and optimization for each application. It all deopends on how much financing is available to be thrown at it.
I’m not used to slapping on something that just works, which I guess makes me the unknowledgable rightwing asshole you’ve so eagerly grown accustomed to correcting my grammar mistakes
Yea, I’ll say quicker spool to clarify it I guess. I think I meant to type “improve” before.
There might be a little confusion here. The key to the whole equation is that I am using a different turbo this year. The turbo is slightly bigger and when tuned on E85 I expect it to make about 100 more hp.
Now since the turbo is a little bit bigger my attention turned to improving spool time by decreasing the amount charge piping and improve the flow of my intercooler to do this with ‘one stone’ me and adam took the time and effort to modify the core that I already had.
The point of the thread was more of a “look at this low cost alternative to back door end tank construction” “DIY and make it better flowing than T1”
The discussion turned to the core since I didn’t point that out initially and my E-rep paid for it dearly :lol
So again:
-a garrett core is better than mine
-my core is effective it cooled my intake air effectively last year
-the air will flow smoother through my endtanks than the T1 example
-I had my own end tanks created after some research and drawings by adam.
-My charge piping length has now been reduced by about 3’
Don’t be stupid. Yes Tony’s stuff (this intercooler) is better than 90% of the shit out there, but that doesn’t mean that there is no room for improvement. His shit is not perfect.
Adam why do you keep talking about 20-30K intercoolers? :retardclap
Secan = A sweet intercooler that is 10x more expensive than it has any right to be.
And for mafdark, your really showing your ignorance over and over again.
Do yourself a favor: Figure out the mass flow of your turbocharger. Then figure out how long it would take to fill 3 feet of 4" charge piping. Then post your answer here. Your answer will be fractions of a second.
Also read this: http://www.turbochargedpower.com/Intercooler%20Theory.htm
all of it. perhaps you might learn something.
Perhaps then you will stop “correcting” people who were nice enough to provide you the correct answer the first time.
:banghead
Feel the need to pull out the strings on that one huh? I do it for the same reason you pull out your unabridged textbook formula talk…because one can.
I used them as a high value reference point. Adding to comments considering prices on available options for heat exchangers. Expensive and typically out of reach ?, certainly. But who the fuck cares? I did read the thread title correctly right???, Compare: IC’s. Seems 90% more on topic than any other thread on this forum to me.
