Afternoon all, thought I would share a little project I’ve been fannying around with! I used to have a GruppeM intake on my E36 325i and loved that induction roar. I’ve done the sound generator mod, but it wasn’t quite the same, so thought I’d have a go at making one. I’ve done a bit of carbon overlaying of parts before and it was good fun. Never tried fibreglassing, but it seemed like fun too! Plus I’m too tight to pay £900 for the real thing :lol:
Watched endless youtube videos and scoured the net for information - including a post on a clio forum where a guy had simply stuck an induction kit inside a flower pot… I didn’t use that idea.
I used high density foam to craft a rough shape, covered it with release tape and then pva release agent. Layer of fibreglass tissue, 2 layers of strand matting, then another layer of tissue. Layered carbon fibre matting over the top, a few coats of epoxy resin and then polished up a little. A little rough around the edges, but I’m fairly happy with the result.
I’ve nicknamed it ‘Group Y’ - the obvious questions being ‘Y would you bother?’ and ‘Y didn’t you just buy one?’… the answer being, as previously mentioned, I’m too tight
Does give a lovely roar when out for a spirited drive. Performance-wise, no idea. Just a bit of fun really, thanks for looking

A rough test of how it would go together
