He made that comment in my thread - In my case the vents ARE to lower engine heat, when the car is not moving, which is the only scenario I have heat problems with the aircon on, sitting in traffic, on 40C+ days. I can't imagine a scenario that this NC needs any at this point in time. I do not know if it will actually make my cooling when the car is MOVING worse, and I sincerely hope that won't be the case. If it does, well, um, f**k. -
Nice, thanks. Thats why I was asking, there'd been a fair bit of discussion in the E90 world about vents and where it makes sense to put one (ie, over the filters is not great as that is inline or slightly behind the struts and in higher pressure area). I struggle with air flow and pressures. It sill weirds me out that a radiator in the boot can work. -
Neither really Vents, when located in the right place, will lower the engine bay "pressure", as air has a path to escape, thus lowering the engine bay pressure, thus.....improving the efficiency on the coolant stack (read: IC, condenser, radiator) This is why the Blits vented bonnet on my 33 worked so well, the vent was in the front 1/3 of the bonnet, which put it right after the radiator If the vents are to far back toward the windscreen, which is a high pressure zone, it can actually force air into the engine bay, causing higher pressure and effectively loosing efficiency on the cooling stack, like the fab of raising the rear of the bonnet, which does allow heat to escape, but only when the car isn't moving There's heaps of cool "fluid dynamics" info out there, but, I'll attach a video of a 'Merican joint that focuses on "Miatas" as I found it when looking into vents for mine, they explain it way better than me -
Poor bleeding. That stupid damping loop in the plumbing that should be completely replaced with a braided hose. Just the first 2 that come to mind. -
Forgive the potentially silly question but are the vents for bay temps? I've been toying with how to reduce my bay temps because man, it gets HOT in there and a small subtle vent somewhere I think might help. Or, maybe they're to assist with just the intake temps?
