Intercooler performance

[mk7_bk]

I have Baun Performance FMIC, works fine. Pretty much all daily drivers will 100% benefit from any upgraded intercooler.

We have the logs, we see that during WOT they get close to ambient. Obviously if your tracking the car every weekend, then it will be a little different which one you might pick, otherwise, feel free to choose the one you want. I don't know enough about the phsyics and chemistry behind the flow. Here is an article on the web (which I will take over mkgolfmk7) "Simply quoting a volume or maximum flow rate does us no good."

"Note: This test is only of flow performance, this test does not correlate with cooling performance. " from the mygolf site.

Not seeing where the vibrant flow test and your article aren't saying the same thing. Seems like they both say cooling and flow should be considered.

Yup... no one want to read that part, it’s more fun to pretent that he lives by his bench and flow tests ONLY...he was aware.

After reading the article its seems there needs to be a good balance between

I only saw the chart my guy. Did not read all the jazz on the site.

It'd be interesting to see a slower flowing IC and a faster flowing IC of similar size on a track car at speed and see which cools better under constant heat soaking like that. IC cooling down quickly between pulls is great for freeway pulls and drag racing, but doesn't seem all that relevant to me.

Also, static flow rates are of little value in my mind, you can only flow as much air to the engine as the lowest flowing piece in the intake system. Until you've quantified which part that is, you don't actually know if a lower static flowing IC is actually a restriction or not. Am I wrong?

I understand what you're asking, but no, that's not how it works. Faster and slower aren't right either, it's resistance to flow. At some point, you'd hit the maximum flow rate through some part of the system, but these cars are nowhere near that. Each part of the flow path contributes to pressure loss (resistance to flow) and the total loss through the system has to be overcome by the compressor. But if it cools well enough, the denser air can deliver more oxygen to the engine at a lower volumetric flow and do more timing advance, which offsets it. More surface area (ei. more, smaller tubes/bars) aid cooling but create more pressure loss assuming the core stays the same size. It's a balancing act; a more restrictive design that cools better can have very similar results to a high flow design that doesn't cool as well.

this guy gets it. thats what i read from the article above its a balance. I thought oh, bigger core is better, but they induce more turbo lag and take longer to cool.

Now someone just needs to write an ideal formula for intercooler size/flow so we have the perfect IC for our cars... Hmm. Anyone know any Formula 1 engineers?

Im sure someone on here is smart enough but doesn't have the tools to do it, aka me

They should all be sitting at home right now.

So then they have plenty of time to whip up an intercooler design

Exactly. Anyone near Woking?

 

[Diggs24]

Yes, I am within Woking distance....

Oof. Got a Brackley joke?

there were some reports the AMS intercooler was for Golf R and that with GTI there is some screw that the intercooler can push into your AC condensor or something like that. So I'd just watch out for that.

I'm getting a better intercooler here soon and on the fence between APR or AMS, leaning more towards APR to be honest.

I have the AMS IC on a GTI and there wasn't a screw that can push into the AC condenser.

Considering he probably got it for free who really got the better deal?

Good point. Didn't realize that, but I guess then both of us got a good deal. And then you can delete my whole first paragraph.
