Which Intercooler is the right one?

[jayrod1980]

I'm biased because I have it but I love my DHM race IC/crashbar. I was even able to install it myself and I've never even changed oil on a car before. I know how but never bothered till now. Russ is available 24/7 for install help and it really bolts up perfectly. You omit a couple interior plastic trim pieces but everything important comes back together and the bumper and all that fit back on perfectly. I will warn about hard pipe kits with the DHM. The end tank inlets seem to extend further back than the stock plastic intercooler inlets and I've yet been unable to install my MAP hard charge pipes with my intercooler. I'm investigating trimming the pipes but can't say anything wrong about it and looks amazing too. I still stare... So shiny!

Went out and did a few data logs today.
Peron tune, J-line IC, EFR6258 turbo.

With the DHM race intercooler I see no more than about 5* in rise over ambient over a datalog run. I believe my datazap is http://datazap.me/u/hijinx

I haven't uploaded much in the way of logs since I had put the aux fuel on. But it's still relevant data if you're looking for charge temps.

I assume your intake air temp is what we Cobb AP users call charge air temp? Meaning post-intercooler intake temp?

Running 23 psi boost, 31 lbs/min of air at 7000 rpm and only getting delta 10 degrees F is darn good. Seems the J-line acquits itself very well.

Too bad you left the gps off, but then again, when you have a fast car, just how fast and where should be private.

Not quite... But in other words, yes. However, when you're looking at datazap/datalogs you want to look at charge air temps. The intake air temps are monitored by the MAF, IIRC.

Yes, intake air temp is measured at the temp/pressure sensor on the cold side charge pipe. Ambient is measure at the temp sensor located in the Rad cowling near the RH head light. Checked this before with a heat gun find out what was what.
The J-line is heavy that's a fact, everything else I have read on the forums is just option and should be taken with a "grain of salt" unless you have data to back it up.
I will get round to measuring pressure drop across the core at some stage. I have a gauge to do this but have been too lazy to hook it all up.

That's incorrect relating to the Euro ST. Read my previous post.

Ahhhh... Sorry about that. I've just learned another of the differences then.

Please always record your ambient!

that is all

No worries, confused the hell out of me many times looking at all the data that you guys get with the AP. Thats one thing I am seriously jealous about.

Depending on how many PIDs your tuner is asking for, that's not always possible.

You can always record all and strip what a tuner doesn't need needs. It's a basic delimited file (open with excel/spreadsheet). Just erks me when I see missing key data from promising discussions.

Helps with DataZaps.

One comment I can make on the CP-E FMIC is that it is MUCH more than just a core with end tanks on it.

We spent alot of time perfecting the size AND the end tanks to make the most of the physical space AND to make the most efficient flow in the end tanks as possible. One thing that you cannot see in the CP-E fmic pictures is the internal fin in the end tanks. What good is a huge core if you only use half of it?

It is also 100% stock fitment. It even lets you bolt in the plastic that goes around the front of the stock intercooler. The end tank end in the same place as the stock end tanks, allowing you to use stock, CP-E and most likely other companies charge pipes. It also reuses the stock intercooler mounting points. It is not mounted to the crash bar.

That being said, it is really hard to really compare intercoolers through datalogs as they are from different cars with different mods in different locations (so different temps). The only real way to do it is to bolt one on one car and take it off and bolt the next one on and keep ALL other conditions the same and make sure it is repeatable.

Also, the best way to measure the temperature effectiveness of an intercooler is efficiency. which is intercooler (inlet-outlet)/(inlet-ambient).

At the end of the day, the best intercooler is the one that puts the biggest smile on the owners face!

Thanks for your correspondence, Mitch! As I said in my email that you got back to me on (Sorry about the comma mishap!) I am very much looking forward to becoming a customer for your intercooler. Very transparent on performance and build quality.

The Pumaspeed ic is a beast! Need to shave the front nose a little to fit. But plenty of upside. Plus if u plan further upgrades this will stay the whole course!! No worries.

The core is nearly double but with the tubular crash bar it weighs less.

Don't worry about a crash, the intercooler core is a lot of deformable structure. I bet it would take a bigger hit to bend the frame with a DHM race intercooler and crash bar than a stock car.

It seems like a no-brainer to me. If you're going to go, go big.

I like the way you think.

Those internal fins inside the end tanks do those affect velocity of the air coming from turbo? Or is there other reasoning behind the fins? Cooling?

 

[Wimp Lo]

The fins are designed to make sure air flows more equally through the tubes in the core rather than using only a portion.

The DHM race intercooler has very asymmetrical end tanks, no fins that I'm aware of but still cools the IAT very well so I don't know how critical fins are.

the DHM Race intercooler has a divider to direct flow in the end tanks, you can see it here in this photo.

I stand corrected and impressed that DHM can put that in without a weld showing in front.
