Has anyone tried using a spacer under the rear of the Targa top, say about an inch or two to make a vent? Since my top has to be and is bolted down in the rear I thought this might help break the vacuum that forms behind the rear window? I have seen a couple with plexiglass/lexan rear windows with several holes across the width which would do the same thing I think?

I can't think of a way to eliminate the low pressure area short of turning the thing into a roadster. Any type of ducting or airfoil is only a partial solution, me thinks.
John: The guy with the air foil was a local guy....great minds & all. (IMG:style_emoticons/default/biggrin.gif) The cooling he got was what he was after and served to indicate that he also got more air back to the lid.... but prolly not to the rear window. As to smoke filling the pilot house.....It seems most all racin' cars fill that spot first when sumthin' goes bang....even open cockpit cars. Some kinda Darwin thing maybe (IMG:style_emoticons/default/laugh.gif) |
