Will this intercooler fit?

No!
What we are saying is that not all changes in direction are created equally.

I can see both sides of this argument and I reckon providing the end tanks have a large enough capacity, room for the air to change direction without hitting too much of a dead end, then whether it is single or dual pass will make very little difference.

That proviso is where the discussion currently sits!

Anecdotally, there isn't much pressure drop across the SEAT FMIC but I await the results of the dyno day with bated breath

(and suggest that the group purchase be put on hold until this is settled with meaningful measurements of the pressure and temperature drops

)

Im with you there. If the end tanks were big enough I guess it would flow in a similar fashion to 2 separate 90 degree bends. Id love to see how it all worked in reality.

You cannot judge the flow by looking at the outside of the intercoolers end tanks either.

The reason the APR one works so well is the internal vanes in the end tanks that are cast in to direct the airflow - unfortunately it adds considerably to the costs:

Guy, any chance of getting a Polo along on Saturday with the APR cooler??

You busy Eddy?

Install instructions for Seat:

The pipework instructions should all be relevant.

Hoyhoy.

Yeah.
Anthony me will be busy spectating you chaps.
Now I have a choice of 3 vehicles to drive up there, which one will I take.

Looking forward to seeing the real life test this weekend.
I may be lookng at this rather simplistically, but the larger the area of the ic, the lower the temp. However the potential for more back pressure.
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.
The same hold true for larger ic's, although there will be a point of diminishing returns.
However lets see this weekends runs. I trust guy will be monitoring charge temp/ pressure vs. Kwatw
