well actually...one of the local MR2 club guys has an AW targa rally car...with of all things a cut down sink....as a scoop under the car....
will find a link for you guys later when I get home from work...

was also thinking about moulding a scoop on my roof...much like the clk gtr scoop..and running it down the c pillars..on my sw though..but it would ruin the venturi effect that draws heat out of the engine bay...

unless it was just for a pressurised cold air box;)...but then one side is dead weight......unless you do twin plenums on a v6 with twin TB's...and filters
