Will this intercooler fit?

[Sharkie]

I'd be happy to kick in some coin to see the wee Blue Girl run or maybe Guy will shout you for being such an awesome customer

Either way it would be brilliant to have an APR intercooler to do some comparisons with.

Cheers Eddy!

Agree with Ant here, Eddy ..... only, I'm interested to see the K04, as that is in my near future ..... BRING THE POLO!

I trust guy will be monitoring charge temp/ pressure vs. Kwatw

This may be better raised in the dyno thread, though what will be measured this weekend? kwatw will be secondary to charge temps and pressure drop as that's the basis of this discussion and limits the variables (which there are still quite a few).

Out of curiousity, does air intake method impact IC temps or flow rate? i.e. PD160 Vs Stock Vs ram/pod style? (or am I getting carried away here?)

Updated list.

We will certainly log what we can within reason on the day - it's pretty easy to check the boost requested vs actual & the intake temps - start & finish - so no problem there!

We need someone to collate the data & if anyone is an Excel wiz, then you can draw up all sorts of nice comparison graphs!

On the subject of intercoolers, there is some excellent information on design & construction here:

ARE Cooling

ARE have been around for a long time & have built some prototype stuff for us over the years, they also initially worked with us on resizing & testing the APR core for the 9N Polo (unfortunately we discontinued it due to lack of demand).

Well worth the time to read it.

So would there be a formula for whats beter... Lower temp, less boost ( cause of pressure) or higher temp, more boost.The forge unit is not good, since it has too much pressure drop, but given the charge temperature drop, shirley it is still beter than the smic.

Lots of variables, temp, humidity, lag, turbo, other restrictions. Even altitude can make a difference. Even perception, a better peak boost may appeal more to some than mid range torque.

I found that in summer the SMIC can not cool sufficiently when not moving (trafic lights, etc) whilst I didn't gain any power from the Forge system, it certainly helped my power in summer.

This is also impacted by the tune, knock sensors, etc, so a tune with more timing may be inclined to pull timing more easily with a little extra temp.

Great link!!!

The Configuration sub section of the Tanks area shows that ARE don't consider the SEAT style layout (180 turn at the far end tank) to be sub optimal.
In fact...

The other design mostly is used in the USA., where tanks are on the top & bottom of the core, causing the charge air to make two 90 deg. bends. By using a second manometer with a long thin probe, we found that 80% of the intake charge flows through the end 25% of tubes on our first test tank, which was of reasonable length. Flow rate was good but cooling rate was terrible. When we doubled the length of the tank, 55% of the intake charge flowed through the end 25% of tubes & overall flow dropped 9%, indicating that this design has too have very long tanks, but should be able to be avoided anyway

A dual pass intercooler is heaps more efficient where both pipes are on the one side, but they require more height for the core.

But it looks like it all depends on the execution of many fine details that are dependant on many factors of the individual installation.

Whatever can be gleaned from the dyno day on this subject will be most worthwhile.

Hoyhoy.

The Little Blue Girl will be there.

I bit the bullet, getting the Seat cooler

I was interested in the THS cooler, but they didn't respond to my message through their site and the costs we've been calculating in this thread were based on being able to use the discount code which seems to not be applicable (so the core is about $600 if you get it through Paypal). $60 for the brackets

Seat Core with brackets and postage to Sydney burbs is under $500 from Darkside Developments website (cheaper than their Ebay store)

-edit- already contacted by darskide, great to deal with.

Good deal.

And good find!! I've been on that site heaps looking at stuff but never looked at the 2nd page of the inlet parts
Ryan's pretty good, isn't he
