Re: Fender vents
Several people have done this. Probably the best location is going to be in the relatively large mostly flat area behind the suspension. Loads are spread out in that area and forming trim will be easier. I'd stay away from the more contoured sections. The forming there allows the metal to carry higher loads so you should try to avoid weakening it. The area in front is another possibility, giving a shorter path out from the radiator.
One other consideration. If you use the typical RV-8 location it means a simpler path should someone wish to install a V-8 on down the road. Jim |

Re: Fender vents
Does this actually achieve very much?
Typically, the wheel arches would be a high pressure area when the car is moving, and have minimal airflow when it's not. Ivor |

Re: Fender vents
Ivor, I think you have that backwards, the wheelwell is a low pressure area and will suck the hot air out of the engine bay when moving. And yes, quite a few owners have reported very significant improvements in cooling with the holes. Incidentally, the airflow out of the engine compartement is generally enough to prevent splash from the tires from entering the engine bay.

Re: Fender vents
The general consensus is that they very much do help with getting the trapped & heated air out of the engine bay.
I have seen heavy mesh screen welded in where Phil did his (ala Kurt Schley), to louvers to real fender exit louvers. Or RV8 headers with a bit larger hole. Personal preference & style. Boating louvered vents come in a nice variety of shapes & styles that could be adapted for this purpose. |
