Late reply, but does a metal coolant tank do anything? I mean, is there any benefit to it aside from looking better?
They do not heat cycle, age, and then crack/leak, but then they ARE harder to quickly/easily check the coolant level, even when they have that external glass tube level check (which can also crack/leak as well).

you are able to see this mountune intercooler is a tube and fin design. This is what I have. This is what is being sold on their website for $599.

also if you watch the video I posted, he explains that the state of the art in intercooler technology - tube and fin is (in general) a more expensive and superior design

Yes Tube and Fin is Superior though the topic is highly debated and I have been down the same road you are trying to go in explaining it to people.
To spell it out simply how its spelled out for the average customer. Tube and Fin will cool off faster and promote better airflow through the core itself. Though the caveat being it heat soaks faster because of that.
It is ess dense and was designed for Motor Vehicles to start. Porsche has always used Tube and Fin intercoolers.

Now where did Bar and plate come in? Its an industrial intercooler core that was never designed for automobiles but got adopted into aftermarket use in part because of certain Bar and plate intercooler companies here in SoCal who promoted it.

The benefits they touted vs Tube and Fin was Bar and plate takes longer to heat soak because denser core . Though it also takes longer to cool down.


On the subject of Mountunes Tube and Fin intercooler it was too small for North America just like our stock radiators were barely passable in certain areas of the country

. I too have a Mountune Bar and Plate because they changed it. They never bothered changing the info on the web page because lazy. Its not the first thing Mountune USA has been known not to do.

When I got my Mountune Bar and Plate in my VB3 package back in 2018 I was surprised to see a Bar and Plate intercooler. So I asked them when I was at the Mountune meet and they were like ya we changed it out to Bar and Plate because the original was not working here, as far as keep charge temps down.

I also found out its the same one being used in their MRX kit their words not mine. It’s been working fine on my S280 with an E30 tune. I am pumping out 340 ft lbs TQ and 310 HP. charge temps are fine.

Unless you bought a used older one from someone you bought a Bar and plate .

Tube and fin look visibly different when you look at the core dead on. The Bar and Plate the bars are more squarish compared to the tube and fin were the tubes are rounded because tubes.

Anyways fact is you can get away with running the Mountune Bar and plate with an upgraded turbo. I did buy a CPE Deltacore for backup but I have not had to install it as I am not seeing heatsoak issues or excessive charge temps.

from what Ive seen it is not easy to differentiate from the front between the 2 types. The core is where you can see which type is which. I purchased mine about 9 months ago.

The CP-E is also a bar and plate, and always has been, correct?

Yes

Tube and Fin tend to be more expensive. Wagner is Tube and Fin, as are the expensive Airtec one that includes a complete alloy bumper support. There are few others I believe

I tried to tell you but you didn't want to listen. I researched intercoolers for years before I made my purchase.

yup, I hate to admit when Im wrong, but this time I am and you were right. The Mountune is a bar and plate even though the description states tube and fin design. Maybe why I never overheat is from the radiator mod then...I dunno.

I NEVER ONCE over heated with a stock FOMOCO radiator with a BA intercooler* Some of us have never dealt with the issue of overheating even running BTs also.

I've got a bunch of different tunes and a Whoosh V2 intercooler - regularly driving in 90+f, usually like a butthead, never seen the temp gauge go above half.

thats good but you really should be following temps on your AP as that stock gauge is like a idiot meter. RaamAudio literally blew a headgasket with that thing sitting dead center.
