Cheers guys. I've not driven the car since October last year (go on...say it) and will soon be getting back into it - have had other priorities,
including some momentary insanitiy which has seen me doing additional modifications to my 58's aircooled....go figure...
VWRX's gearbox is my main priority, then to tackle to cooling issue. Did I mention wheels, brakes and engine too??
Don't worry Wes - I'm up for a 'little effort' in sorting this out.... look at the effort that has gone into the car to date....
Based on my review of revisions required and costs associated I will be moving forward retaining the current radiator location with appropriate
shrouding to the front and rear of the core, and installing a new aluminium core (the cheap commodore core has had it...).
I've also considered angling the core rather then running in a vertical position. I would guess laying the top of the core forward would assist given
the air will be drawn from below the nose, however by doing this appropriate shouding will be required to the back of the radiator too as the
aluminium fuel tank acts as a huge heat sink - hot fuel and fuel pump is not good...
I've also considered laying the top of the core back so to blow hot air down under the car, however this limits the free space for air intake at the
front of the core and potentially involkes some recirculation issues...
I'll be sure to post pics as I progress, including templating of shrouds etc.

Yeah, my bottom radiator hose goes to the passenger side and the top hose goes to the drivers side. My top outlet has been flipped to face forward
rather then the back of the car.
Very observant dude

Hi
I dug my old fan shroud that I used on my yellow bug. Its from a 1979 Audi 100 CD.
After seeing the small size that other people are using with their WRX conversions I'm thinking of going to a smaller radiator.
You can see the rubber flaps that are used on many VW?Audi cars. The flaps blow in the breeze when the fan isn't on allowing maximum flow through the
core at highway speeds, when the fan comes on the flaps get sucked onto the radiator fan housing so that the fan only draws air through the front of
the radiator.
Steve

mate 4 words...
"do not move it!"
it's all about airflow and ducting like Boof said. I have a smaller rad than you. about 40% is exposed to the open airflow at the front and the fans
don't come on unless the car sits for a long, long time. If you can, box in the back of your rad and seal the fan via a shroud it will make HUGE
difference. A small gurney flap (like a nascar rear wing) under the car at the back of the box will create a significant vacuum behind the rad and
draw the air through it. combine that with a small scoop at the front like others have said and it will work even better.
Lots of cars have front mounted rads like yours and work very well.

remove the indicator lenses and use them for ducting if there is enough room infront of the wheels , run the large flex piping or aluminium ducting,
then place a led light setup for ind . just a thought.
