I'm thinking about doing a DIY extraction hood. The pressure numbers here support the idea, and I figure it'd be a good functional mod that I can work on in the basement as my tinkering-itch is getting BAD this wisconsin winter.
I'm planning to do something similar to this one from m.n, except I'll be painting the mesh either black or dark green to match the paint to make it less "rice"
I'm also thinking I'll cut the holes on both sides, and put mesh in all 6 holes, but cover the back 4 holes so that the only *actual* vents are the ones almost directly behind the radiator in a really good spot to be "real" extraction vents.
I thought about only cutting the front ones, but I think it would end up looking like a big pig/cow snout, and I like all 6 holes cosmetically a little more...so I can just block off the rear ones. Or I could do some testing and see which holes uncovered gives me the best IATs/coolant temps/etc.
What do you think? Both sides or just one side? Or neither side?
I did some digging in old threads and found that--much to my surprise--the general population of MT.N is pretty accepting of DIY vents (as long as they're functional) so I feel like I can probably ask this without putting my flame suit on (although I'll keep it close at hand... :P)
Pardon my crude MSpaint skills, but this might help demonstrate what I'm thinking. Keep in mind, teh car is emerald mica, and I'll either be painting the mesh black or emerald mica to match.
