Gents,
Im working on putting together my 914-wrx and Im exploring venting options for the front radiator. Im trying to think about it from a performance perspective and Id love some feedback to see if my assumptions are correct. Up and out of the hood: Needs venting of some kind. Either louvres or a big hole, but seems like the most efficient way not only get air through the radiator but also the best solution aerodynamically. True? Wheel-Wells: It looks like a common option is to vent out of the wheel-wells. Cut a huge hole, put some mesh on it, done. This seems bad as its blowing hot air onto the brakes, but maybe the temp difference doesn't matter. Its tempting though because I don't have to cut holes in my brand new hood, but aerodynamically speaking is it not efficient? Pushing air into the front wheel-wells... seems bad, no? Under car: I know this bad for a variety of reasons, so its really not an option Im considering Yeah, so what Im really wondering is, if you were building a track-focused 914, would you vent to the wheels or out of the hood? |

Ya gotta be careful. The SCCA very specific hood venting rules. Read the book before ya start hacking.
This is a legal job of it. |
