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? |

My Suby conversion vented through the hood. Exit hot air on top of the car, not under it. I agree. I think a lot of the through-hood vents looks pretty bad though, ill proportioned, tacked on... I was initially thinking of going 911-style by diving the hood down into the radiator but I may have changed my mind. Im thinking louvres are the way to go visually speaking. Going to experiment a bit, we'll see... |

I am not a fan of most methods used to attempt to "hood vents"...not really a fan of most louvered efforts as well - some are ok. Very few cars had "appendages" sticking on or out of them - clean and simple - kind of like the mid-2000's Ford GT. Pull that off and that would be cool as Hell (I've thought about that!).
The previous owner did something really simple with mine. He literally cut three sides of the hood where he wanted the vent. Bent it down and blocked and glassed it in. It does have a screen at the opening too. It flows nicely with the hood; isn't' the absolute best with rigidity but that's mainly due to the light weight fiberglass hood. Overall, it was one of the main things that attracted me to this chassis. Good luck. I agree. I think a lot of the through-hood vents looks pretty bad though, ill proportioned, tacked on... |
