Do you have a picture showing the entire housing on where you cut with the older and newer cut holes? Also have you gotten caught in any rain with it....if so how did she act?

Thanks for the reply

As you know, it's not my daily, and the drain holes at the back of the housing are still there and functional. I tried to drill at some of the elevated points on the housingóhaven't noticed any ill effects to date. Been like this for about 3-4yrs. now. I guess one could always use some tape (over the holes) or something as a temporary means if you were worried about water entering the engine compartment while washing.

Been talking to a guy on BF that laser scanned an e46 M3 model and did CFD on it (for club racing). I wonder if this might be a better way to go than trying to DIY it from a CAD model.

Anyone interested in splitting it? Or, streamline, any interesting in buying it for the hood development?

A Sauber F1 engineer did the CFD. Probably better results than me doing it

As said in the CAD model thread, I was also thinking that we may be able to pull pretty accurate exterior e46 M3 models from the Forza resource files.

That's where I added the additional holesócan't see them from that photo. Nah, sorry man, I don't have any additional pics...I'm not very good at documenting stuff sometimes-lol. It's not my daily, but the one time that I did get stuck in the rain, there were no adverse effects.

The engine bay is pretty water proof-- I can't see any issue from there.

The negative effect I see is the air going into the climate system is hot, making it have to work a lot harder, and potentially stinky, if you have any leak.

If you wouldnt mind and can find some time...do you think you can pop the cover off and take the filter out so you can take a few pics for us? Id like to see exactpy where you you made the holes.

Someone mentioned above removing it completely caused issues in the rain but also saw lower bay temps in normal dry conditions. Even tho cutting isnt removing it completely...if cut in the same area that gets whatever wet then you can possibly have those same issues.

With stan reporting no issues in several years id like to replicate where he has cut the holes.
