cskip Posted June 13, 2003 Share Posted June 13, 2003 Where is a good and cost effective source for exhaust packing? I need to pack my Techcraft to the gunnels for a Goodwood Track day! Skip. Link to comment Share on other sites More sharing options...
Drumster Posted June 13, 2003 Share Posted June 13, 2003 Being totally lazy I just called Chris Wheeler at the 7 Workshop and asked him to send me some. Had to part with some beer vouchers though 😬 Chris Alston www.C7CAT.com 1800 Supersprint Drive it like you stole it! 😬 Link to comment Share on other sites More sharing options...

Nick M Posted June 13, 2003 Share Posted June 13, 2003 This is probably going to spark a flurry of messages about why you shouldn't do it, but I use loft insulation in my silencer.... Getting the proper packing material over here is a bit of a pain - for some reason repackable silencers don't seem to be that common - and so I went to the local Home Depot (B&Q) who had some small bags of GRP insulation for about $5 each. 1 1/2 bags did the job and it worked OK. It didn't seem to get too burnt (it's got a fire-retardant in it before anyone gets too excited !) and lasted reasonably well. Certainly no worse than the proper stuff that was in there to begin with. Might be worth a go if you're stuck. Link to comment Share on other sites More sharing options...
Big Brother Posted June 13, 2003 Share Posted June 13, 2003 Interesting Nick, There is a post running at the moment that has touched upon this very question here A friend of mine who is an accoustic engineer said that loft insulation would be fine in a silencer, as long as its packed pretty tightly. He also recommended wrapping the perforated tubing in a thin layer of steel wool. I thought he was joking as so many companies sell "specialist" packing. Obviously he was right 😬 Steve Se7en-Up! Less is more! Eagles may soar, but weasels don't get sucked into jet engines! Link to comment Share on other sites More sharing options...

AMMO Posted June 13, 2003 Share Posted June 13, 2003 I was up in my loft the other day. Although it was pretty warm, I'm sure it was nowhere near 600 degrees C. 😬 AMMO Link to comment Share on other sites More sharing options...

And as for you AMMO - 😬 😬 BTW, John Christensen in soggy Seattle was most impressed with the silencer I recommended that he pack it with loft insulation too* 😬 😬 *don't worry, that's a fib !! 😬 Link to comment Share on other sites More sharing options...
Paul Ranson Posted June 13, 2003 Share Posted June 13, 2003 You could always have TechCraft send you some. Paul Link to comment Share on other sites More sharing options...
