Will this intercooler fit?

[Sharkie]

I wouldn't be so quick to say your cooler is better than the SEAT.

Just going off real world data from a VDCS I can easily show with logs that after more than 6, 3rd gear pulls to just over redline up a steady incline back to back with just a u-turn in between the SEAT cooler did not register temps more than 30 degrees at any stage. I have the logs that I can email anyone who wants them (thanks Gav) I think you'll agree 45 degrees v's 30 is a bit of a difference even when you take ambient temps into consideration.

I guess this Saturday will confirm everything.

I'm going off actual intake temps measured with a probe at the last Polo dyno day. APR FMIC did 44.x, mine did 45.0, other FMIC did in the 50s and stock SMIC did 70+. On a day that was summer & 32 degrees outside and even hotter in the dyno shed .... this time around we have a nice open space, winter and a massive fan helping the cooling.

I'm happy to wait and see the comparative results on Saturday.

I think we should have a Bang for your Buck category as well ..... how much $$ per kw gained (from stock) ... be a few surprises in there I think.

Fair enough mate some good data there. My only concern is your comment

IMO much better than the Forge/Seat/this latest etc .....

When there was never a SEAT cooler there at all for you to form an opinion over.

I just though I would bring attention to this so the guys who are trying their best to organise a group buy in this thread are not misinformed by an unjustified opinion.

Really keen to hear the results from your dyno day now - I went forge purely because of price, would love to have stayed OEM and gone SEAT so I didn't have a random front bar lying around in my garage...but ahhh well, maybe in the future.

My opinion had nothing to do with the thermal aspects of the coolers ..... its all around the flow and for me there is no way a cooler of the SEAT and Forge design will flow as well as the APR style one. For air to be performing a 180degree turn and to expect good flow characteristics just does not make sense to me.

As far as I'm concerned a straight through design works best, followed by the APR style, followed by the SEAT/Forge design a distant last. Happy for a flow bench to prove me wrong .... just not seeing it until then.

[VWindahouse]

Well if you read your comment again the thermal aspects are exactly what you were referring to. Not the design.

For those in Brisbane coming to the Dyno day, have a chat to me about the FMIC I have on my car. Similar in design to the APR FMIC. Lets see the Intake temps after a few runs ..... (I have seen it before )

And for this comment

I don't understand what your trying to say to be honest, all the cores are a 180 degree design??? None are a straight through version.

[Sharkie]

Actually, no..... APR style (for the Polo and MK4 GTI) is a 90degree design ..... straight through not common on Polo's. I'd do 1, but it would require an intake manifold with the intake on the other end.

Example of the classic and most efficient Air to Air IC straight through design ....

[Sharkie]

Awesome, can it go both ways? $$$?

[VWindahouse]

Sure can bud. Looks like it will be around $600 US when it gets released. Here is the teaser link

VWVortex.com - *** 034Motorsport - Transverse 1.8T Intake Manifold Teaser! ***

Massively increased flow

Or you can just do this



Yep it's a Polo!

[Sharkie]

It is now on my shopping list ...

[nightphotographer]

That would make it a lot easier to find a custom cooler and dayum it looks good!

OT with the intercooler differences, I see how many rows and the length of the rows as a key difference.

Sharky, I'm surprised you are seeing such the low temps given how short the cooling bars(?) are.

Given all this bending, etc happens under pressure, I'm unsure how much difference doing the 180 in the end tank vs through the bars would make. If you look at the standard XR6T intercooler, it does something quite similar.

Testing should be interesting, hopefully will yield some usefull data.

Sorry but how is this not a 180 degree flow shift (90 + 90 just like the others)?

..... straight through not common on Polo's. I'd do 1, but it would require an intake manifold with the intake on the other end.

My concern with this sort of design and the plumbling required is increased lag from the greater air volume between the turbo and the inlet manifolf.

The air does not have to turn 180 degrees inside the endtank on sharkies unit.
It does a 90 degree bend. through the cooler then another 90 degree bend.

Would be interesting to compare the flow and whether the 180 degree design generates turbulence or restriction

So what we are saying here is that 90 + 90 doesn't make 180?
