I've read a bit about sound deadening and one technique is to fill hollow spaces with expanding foam to kill resonance. I was thinking of doing this to my roll bar top and maybe the sides. Knocking on the top shows how high of resonance it has. I was think that if I drilled some hols 8-10 inches apart on the underside of the roll bar and sprayed in the foam I could kill the resonance and just fill in the holes. I'm not sure I could weld them since the foam is in there, but maybe solder or lead them in, or maybe just bondo?
What's your reaction to this? Good or bad idea? |

QUOTE(sechszylinder @ Jun 25 2003, 03:46 AM) Jeroen, you're absolutely right; a 914 owner has to live with the fact that this car is noisy I'm going to play the devil's advocate here and say that no, a 914 owner doesn't have to live with anything. To each his own and cheers to the inovators. "Can't turbo a 914" - disproven "A 914 will never shift as well as a modern car" - disproven "Carbs are cheaper than PEFI" - disproven "914's are all noisy. Live with it." - jury still out -Ben M. |
