[urq] Intercooler scoop

[Ado Sigal]

Hi

Along same idea, I approached the IC and oil cooler efficiency slightly 
different and got positive results. The IC impro requires removal of the 
IC steadying bracket and drooping the IC down and fixing it via moulded 
mounting ( from the IC bracket) directly to bumper shroud plate, and 
sealing the gap with closed cell foam strip. Top is sealed by a plastic 
plate cut from a wheel arch shroud, which slots in the top of the IC 
slot made by gluing the alu profiled plate with windscreen mounting 
polyurethane at the inner top end of the IC. The slot is about 2 cm 
long, to allow sufficient shroud aft and for movement, by which the 
front of the shroud slot is inserted into the ex IC steady bracket 
point, then secured by the plastic pin. The left side gap is sealed via 
close cell foam, and sealed part of the spoiler slots are cut open. The 
right side is also sealed by close cell foam. This setup works very well 
as it was with alu plate, but the alu plate was noisy and more difficult 
to fit.
The oil rad air scoop was also improved by fitting the bottom lip to it, 
and all round sealing of the rad - scoop gap with glued rubber profile 
from a sunroof wind deflector. First lip was made of alu, but was later 
changed to plastic (from same wheel arch shroud), because it tended to 
get damaged by high pavement edge. Works very well and max oil temps are 
down by cca 15 Celsius. Prior to mods, the cores where cleaned, 
deblocked from stone glass etc., and finns where realigned. Furthermore, 
the IM, own pipe and the block are also covered with alu temp shields. 
 With this setup, the temp problem has been largely resolved, and feel 
that only water injection could improve it further.

HTH, cheers,

The oil cooler shroud I bought recently just melted under there.  I understand now why they put the IC up front and the OC un top of the trunk of the works cars.
