bspeed Posted December 12, 2010 Share Posted December 12, 2010 R400 Duratec too noisy for Goodwood. Will a Raceco silencer be sufficient. Car on standard CC silencer was 103db static but needed to be 98db. Car is 2.5 years old with standard plenum etc. Any cheaper alternatives as only about tracks where it will be a problem Link to comment Share on other sites More sharing options...

Sigmamark Posted December 12, 2010 Share Posted December 12, 2010 I run a 250 bhp K series with a Raceco silencer and always pass at about the 97/98 level. I've no idea how the Duratec compares noise wise, but the only problem I have is any "drive by" testing because of the throttle bodies. Link to comment Share on other sites More sharing options...

Area Representative Nick Chan Posted December 12, 2010 Area Representative Share Posted December 12, 2010 Surprised to hear that an R400D was too noisy as the ones I have heard have been significantly quieter than their K series counterparts (the roller barrels don't help too much!) but sounds like MH has sorted you out Back in a BEC! - but done alright in Class 1...

dickbowyer Posted December 12, 2010 Share Posted December 12, 2010 My SV R400D has always been too noisy for G'wood quiet days despite large race silencer. Always wanted Raceco box but fabrication issues with shortening of collector have always put me off a bit going down that route. If however there was an off the shelf solution would be the first in line. Induction noise however remains an issue without going to TBs and air box.

Pat the Plumber Posted December 12, 2010 Share Posted December 12, 2010 i got retested at Oulton in October, but will go down the Raceco exhaust when the noise levels get more strict my R400 Link to comment Share on other sites More sharing options...
