[s-cars] Lower Turbo Hose

[Tony Curran]

I notice that the 225hp 1.8T engine comes with two in-line intercoolers and
thought that might be a nice upgrade if dollars for FMIC weren't available.
So I picked up a neu-S4 intercooler for $30. Now I'm trying to make it fit
without destroying anything so I can return to original state if it doesn't
work out.
 
The neu-S4 intercooler has 2" pipe work which suggests the higher pressure
created cos of that would be helpful, yes? Or detrimental? Also the
temperature at the throttle body would be lower cos of the two cooling
elements, which is beneficial, yes?

Why would you want all the pressure drop of a 2nd intercooler when it's just
as much work to make a single efficient one?

What would happen if there are no angles, i.e. if the hose went straight
from turbo hose to BPV?

I planning on adding second intercooler a trying to make space for it (will
have to move the horns as well).

Air doesn't like extreme angles, so a few 90's is better than a tight angle,
which would also pulse against the valve & possibly surge.
