Competitive Dad Posted August 8, 2002 Share Posted August 8, 2002 I have recently acquired a factory standard Caterham 7 Cosworth HPC. Great sound but too noisy for track days. Which silencer should I fit? Also I read that a "MSA acceptable role bar" is required. I assume my car doesn't have this. Again what do I fit and where do I get it. Thank you in advance for any advise. Link to comment Share on other sites More sharing options...
ECR Posted August 8, 2002 Share Posted August 8, 2002 Raceco (advert in Low Flying) should be able to help with the silencer. Alternatively Tech Craft at Warwick. The bigger the better !Both these types are repackable so that you can refresh your silencer when it gets a little noisy. No doubt others will be along soon with alternatives. The FIA Roll over bar can be supplied by Caterham. Look in competitors kornersprinting specs 2002 (from the homepage on this site for information on roll over bars) Edited by - ecr on 8 Aug 2002 13:23:49 Link to comment Share on other sites More sharing options...
EFA Posted August 8, 2002 Share Posted August 8, 2002 Isn't the "Blue Oyster Club" a role bar?? (Police Acadamy....) Glad to see you realsied he meant a "Roll Bar" Roger Link to comment Share on other sites More sharing options...
greg Posted August 8, 2002 Share Posted August 8, 2002 John, lenght is apparently as impoortant as width when it comes to makeing things quite. ie a 7" is better than 6". This posts sounds a bit rude to me Greg, Q 86 NTM (Green 185BHP XF) Link to comment Share on other sites More sharing options...
EFA Posted August 8, 2002 Share Posted August 8, 2002 Greg, Is that small talk overheard in the Blue Oyster Club, or technically correct info I wonder??????? *wink* Link to comment Share on other sites More sharing options...
greg Posted August 8, 2002 Share Posted August 8, 2002 I sure it was PC or Mike Bees, but could be wrong..... Not casting any dispertions. Blue Oyster style bars can be found in Brighton, I've got some friends whom would take you and you could ask .......

simonwelton Posted August 8, 2002 Share Posted August 8, 2002 Mr Welham (very formal!) notwithstanding the rights or wrongs of FIA (MSA) rollbars versus others, to my knowledge there is only one track day organiser who insists on the fitment of these. That is this club (and quite rightly) however there are LOTS of track days you can do (at your own risk) without any roll bar should you chose.

New Barbie Posted August 8, 2002 Share Posted August 8, 2002 John I wouldn't assume your rollbar is not FIA approved, I reckon I see more FIA bars on Caterhams than the standard effort. What does yours look like ? (waits for stupid replies as well as the serious) If you have a diagonal brace in addition to the standard rollover bar and rear supports, it's 99% an FIA bar and fine. If it's thin, no diagonal and looks more like a bent wardrobe rail, you should change it disregarding any track day intentions. Ignore the other replies, they don't get out much.

STEVE GILBERT Posted August 9, 2002 Share Posted August 9, 2002 Buy the Raceco silencer, top kit and no mistake. Link to comment Share on other sites More sharing options...
Steve Ashurst 63 Posted August 9, 2002 Share Posted August 9, 2002 I bought a Cherry Bomb bolt on silencer from Demon T to get me onto Goodwood for a 97dB day. Worked a treat although I had to saw the rolled over end off the existing silencer before it would slip on. Cost £45 , well worth it and it allows me to keep my noisy silencer for road use. I have an HPC also and the power drop wasn't noticable - still caught a 911 turbo by the 2nd corner ! Link to comment Share on other sites More sharing options...
