Intercooler upgrade

[M1rider]

Out of the code 3, agency power, and Rd intercooler upgrade which would you say has the best gains cooling and the easiest install.

Exhaust prototype #2 is on its way, had to change some things for the twin turbo and fit for the 135i

cool, thanks for teh update!

Haha..I love how everyone posts the one he DIDNT ask about

Course that's simply truth and reality, in my eyes as well HPF looks to be the finest, most well built and performing of them all. And VERY sexy looking to bat.

Ill be going with that most likely next spring

HPF hands down!

[ETS Michael]

I had a customer who was thinking of switching from the ETS core to an HPF core and we stumbled upon some interesting facts that you may want to consider.

ETS Core

10 - Charge Rows
19 - Heat Transfer Plates
5/16 - Tube Size

.312 x 5.0" Thick x 10 Charge Rows = 15.6 Cross Sectional Flow Area

5.0" Wide x 20" Long x 19 Heat Transfer Plates = 1900 SQIN Heat Transfer Area

HPF Core

7 - Charge Rows
14 - Heat Transfer Plates
5/16 - Tube Size

.312 x 7.0" Thick x 7 Charge Rows = 15.28 Cross Sectional Flow Area

7.0" Wide x 20.25" Long x 14 Heat Transfer Plates = 1984.5 SQIN Heat Transfer Area

-------------------------------------------

The above information shows the ETS has more Cross Sectional Flow Area in a smaller package, but the HPF has a greater HTA by 84.5 SQIN. There are a few other things to consider when looking at the cores though. The fin density plays a huge part in heat transfer, we use a very dense core which contains many more fins for heat transfer.


ETS Core vs Standard Design Intercooler Core (You can see the difference in density where heat transfer takes place)

This post is not to bash HPF, just show that sometimes bigger isn't always better (I'm sure this will open it up for jokes) The ETS core is also a direct bolt on with no cutting and includes an intercooler pipe to get rid of the restrictive factory pipe.

We have a full tech article here.

I gotta say right off the bat, that HPF's near 100% positive rep as well as the intercoolers usage of OEM connector brackets to fit onto the piping make it my #1 choice. Silicon hoses and t-clamps always allow the possibility for leakage and flex. The quality, size and look just further add to that decision

[onefastman]

I have ets and for the money it is the best option but I am not so gullable as to think that it is better than hpf.

Get a hpf or cp-e.

Whats the weight of the HPF? No doubt its a great product but I understand its a significant weight increase. I like my AMS

[thez99]

If anything it may be a few pounds heavier, by far from significant. Anyhow that wouldnt sway me a bit

x2 on the AMS

My AMS was a simple install (less than an hour) and looks great. Performance from intercooler to intercooler is negligible.
