I've got an aftermarket front cooler that currently vents up through the hood. I want to change it to a more discreet set up to get past vintage tech.
Does anyone have access to photos of how the original GT's were done? I understand they blew out the bottom of the front trunk area through a louvered panel that created vacuum when in motion. I do have access to sheetmetal working equipment to build the shroud around the cooler. Cutting louvers is a bit of a different story - would prefer to buy that panel, but making it is not out of the question. I recall a segment of "Binky" where they punched louvers. Will never show so doesn't have to be pretty. My alternative is to fab a box with round vents ducted into the wheel wells. Thx. |

Here's a thread from Pelican from a guy doing what appears to be an accurate GT repro (or maybe resto?). It doesn't look like he did the louvers on the bottom. And honestly I think I'd skip that too. Louvers won't have as much open area and may not vent the cooler sufficiently (you want the cooling exhaust to be at least the size of the cooler and preferable 1.5x the size). A low front spoiler will "trip" the air to create the negative pressure you need for the oil cooler exit in the trunk floor, or you can add a lip at the leading edge of the opening, worst case.
The accurate metal GT ducts I see look very expensive (over $1000). I'd fab something similar if it were me, or I think I've seen fiberglass ones that are cheaper. Try mb911 here on the forum - I seem to recall he has GT repro stuff that is nice and reasonably priced. http://forums.pelicanparts.com/porsche-914...-project-5.html |

Lots to work with there. Now I see why the PO of my car simply blew a hole in the hood and winged together some ductwork ... Many thanks. |
