Radiator Cover Hole

Post by lucasxdiniz » Wed Nov 15, 2023 12:46 am

Hi all,

Does anyone here feel bothered by the big hole in the front of the engine bay where the non-Ms would have their expansion tank cap? I can see why BMW chose to re-use the part (a new tool would cost £75-100k for a part of that size), but I can't help but look at that hole whenever I open the bonnet to stare lovingly at the engine (fairly often).

I'm interested to know if people would want something like this in their car. The only viable manufacturing option here is 3D-printing; I will be looking at SLS/SLA in either glass-filled nylon or tough resin. If there's some interest, it will influence how I design the mounting method and, potentially, I could get a better deal from a 3D printing company if I'm ordering a few units. I reckon to print a 1off for myself will be around £60-100 depending on material and process.

I will be driving the car with temperature stickers where the 3D printed part will be, that will drive the material decision really.

Can’t say it’s ever bothered me, but I think one or two have covered this area with something so you’re not alone.

I'd also be interested if it match the colour/texture of the rest of the plastic shroud :thumbsup:

More interest than I expected to be honest. I'll spend more time on it this weekend and hopefully print a prototype next week.

I too want the finish and texture to be the same, but that is almost impossible to achieve without some finishing process. I am expecting a bit of sanding and painting to be needed to make it look OE. I'll report back once I actually have one installed and people can then decide if it's too much effort for them to deal with or if it's cost effective for me to do it for them.

Feedback on the ///M logo placement and size is welcome. Can possibly tailor individual prints and add/remove features.

I am 90% sure someone on here did a full cover out of Carbon Fibre, and am 50% sure I came across a similar plug to what you want to do lucasxdiniz, might be worth doing a search :thumbsup:

If you can't get a perfect match then it looks better to make it something contrasting IMO.

Yes, I was thinking that too! M placement looks fine, but you could make the M a bit bigger!

Looking forward to seeing your prototype anyway. :thumbsup:

Just wondering: could you do manhole-sized ones?
And could you post to Las Vegas?

Yeah, I agree. That's plan B essentially.

Personally not a fan of the exposed carbon look. The only thing I'd have from Skyer is the aero skirts if I couldn't find OE ones, or the carbon roof if mine got badly dented - I'd still paint it over though.

I did use the car to commute to and from work a couple of days and on the way back I was able to get it nice and hot, but due to the greasy weather, couldn't really get the oil temps over 100°C, which means I didn't get the car anywhere as hot as it could potentially get.

Does anyone have any planned hooning this month, I can send you some temp stickers to get better data. Let me know.
