In my never-ending quest to keep the beast cool, I'm looking at reducing underhood temps as much as possible. I'm thinking about adding vents or louvers to the hood, but I have yet to see an e30 with a vented hood that I actually like. Anyone have some pics or photos of e30s with vented or louvered hoods that they care to share? Looking for some ideas/inspiration.

Here's a tip I gleaned from vintage sedan racers: instead of louvering the hood, prop the rear of it up as much as possible. This helps the hot air flow out in a pretty direct path and doesn't require any cutting. It helped our customer's Cortina immensely, and that car came to us with hood louvers.Interested in vintage cars? Ever thought about racing one?

I mean its a convertible so you kinda got that alll natural AC haha so it would just make your heater kick ass in the winter. Imo hood vents should stay on the race cars as far as the e30 goes. Then its function over form cause nothing looks appealing really like you said

B. Weird fitment/body lines
C. Big holes in hood, silly louvers
Is this an engine swap or something? Why's it running hot?
Edit: Just saw your sig. Yeah, I mean you have to choose one of those, or get some extra air in/out with tubing.Last edited by ELVA164; 03-01-2017, 08:07 PM.Interested in vintage cars? Ever thought about racing one? Info, photos, videos, and more can be found at www.michaelsvintageracing.com!

M30 swap with m106 turbo setup. Its one busy bay with lots of heat producing parts.
