911/ 930 Engine Bay seal(s) anti heat convection seals (Occam's Razor)

[Hippie 930]

I am the proud owner of a federalized 1984 Porsche 930 since 1985 and converted by RUF USA in 1986. At the present...39,701 miles. It looks almost new or slightly used, See pics...

Although I do have the front spoiler/ oil cooler upgrades to assist in engine cooling/ lubrication, and never having had any issues with over heating (Florida summers). I looked and evaluated, as well as asked many "Porsche gurus" what to do when deleting the heater system ducks/ heat exchangers while installing headers.

The goal is blocking the potential convection heated air flow from under the engine exhaust pipes/ headers, performance muffler/ turbine (K27) from escalating (hot air always go up) into the engine bay and interacting with the air conditioner condenser, engine heads, sensors and intercooler's thermodynamics efficiency.

Over the years, I have seen all kinds of fixes, modifications, seals, barriers, etc.; from aluminum patches to silicone pads or foam insulation with price variations and fire resistant properties that can really make you go crazy...

Even having seen most of these customizations, over the almost forty years I have been exposed to Porsches 911's, I always thought there should be something better, something that settled these annoying perforation remnants for all time. I was not wrong...I found the ULTIMATE SOLUTION, for all time!

Here are some of the pictures from a Lowe's 2 " galvanized knock out seal worth $2.

I painted them both (one for each side) with Dupli-color enamel (Porsche code) in black, let them dry, repainted them a few more times, opened their holding pins slightly, and then installed them from the bottom up... 1-2 & 3....Snap!

From my view other than welding galvanized, this is the best option.

Thanks Chris from TurboKraft Lou from Aero Dynamics, and my friend Jose for their guidance and support which took me in an investigative journey for the BEST OPTION, even as their solutions are good, I seriously believe this IS the one!

The project made me read and review all sorts of informational sources as I began its quest from books to the local Fire Department station to, finally, a great young man in Lowe's hardware electrical section pointed me in the right aisle looking for a heat resistant shield not prone to ignite (foam / rubber were discarded) or else with the engine/ exhaust/ turbine generated heat.

Pics speak for themselves...enjoy!

Simple, no issues.

Occam's Razor theory...making complicated things into simple concepts and solutions...Yeah!

Be well, Carl.
