Alternate cooling solution for the alternator

I was inspired by Perry and others to add a cooling hose to keep my
alternator & its regulator from over-heating after adding the VF SC kit.

After a track day at Laguna Seca (daytime temps maxed out at 65 F),
i could feel that the striped, black hose (see pic 3) was cool in front
of the orange cooling hose but warmer closer to the engine block. This was verified
by another Lotus driver, Jerry. I could even put my fingers on the alternator
regulator and it wasn't hot.

Below are pics of
<ul>

<li>Inside of the passenger wheel well (pic #2),
<li>Pic above the alternator where the hose was compressed to a rough oval shape to fit below the black hose with the reddish stripe (pic #3),
<li>ABS plastic sheet used to form a shroud to limit air movement (preventing air from going behind or above the hose on the left, but allowing air to flow thru the hose and to the right of the hose (pic #4)
<li>Shroud installed after bending it to fit. (pic #5)
