Incidentally, "flow" rate will actually be higher than 77%. The 77% rate is amount of stagnant fill with mesh versus wide open. The flow rate could be a bit lower than wide open but won't drop anywhere near theoretical 23% based on amount of fill the mesh provides.

I did similar (IIRC rated at 80% fill) 5-6 years back on my 997 C2S. Even after numerous HPDEs in 95F hazy, hot, and humid weather w/ 30+ min sessions, only effect has been easier cleaning of condensers & rads... No to mention, I haven't had to replace one AC condensers since installing mesh either - wish I'd done after I lost first one years ago... Bottom line, I have experienced ZERO negative impact to cooling efficiency/capabilities (as nay-sayers to this mod will try and proclaim).

Good luck

Hi Burg, thanks! And thanks for the clarification regarding stagnant fill vs flow rate. Good to know that your real world experience supports this mod. I just could not leave two condensers and three radiators in the open for street driving. I made a similar mod for the oil cooler on my R1100s.
