Mike Molloy Posted June 10, 2005 Share Posted June 10, 2005 Before you do anything foolish, try strapping 100kg of lead to the front of your chassis and see if you still like the handling!!! 😳 Link to comment Share on other sites More sharing options...

Dobuy Posted June 11, 2005 Share Posted June 11, 2005 Ross & Myles, Surprisingly cheap to do at bulk air rates and probably available for collection at a International airport within a week. I am actually seriously considering it as otherwise it will be sitting around in my garage making me feel guilty Duratec SV, built in Dubai Link to comment Share on other sites More sharing options...
Ross_H Posted June 11, 2005 Author Share Posted June 11, 2005 dobuy..why the 2.3 conversion...i thought it was relatively easy to get more ponies out of the 2.0....as an aside how do people get on with track day noise on duratecs? Link to comment Share on other sites More sharing options...
AMMO Posted June 11, 2005 Share Posted June 11, 2005 Ross Duratecs are incredibly quiet. I can now drive my car without earplugs. When it had a Zetec and before that a Crossflow the noise was unbearable. I know that before my car was 90 dB in the cabin with the noise meter at ear level at 4000 rpm. Must check again and see what it is now. Neighbours and a few people at the club meet at the Cornwallis also mentioned that the car is less noisy now. Don't think you will have any problems at track days (if you have the right silencer!). 😬 AMMO Link to comment Share on other sites More sharing options...
Dobuy Posted June 11, 2005 Share Posted June 11, 2005 Ross, the reason I went to 2.3 is that I managed to find a really cheap 2.3 engine ($800) and wanted to do some engine building, then of course things started gettin silly........ No problems with noise here in Dubai Duratec SV, built in Dubai Link to comment Share on other sites More sharing options...
MikeE Posted June 11, 2005 Share Posted June 11, 2005 Sorry to contradict you AMMO but, yes my car (and DannyLT's 250bhp 2.3l R500 Duratec) have had noise issues on trackdays. I've got the 'big Raceline' silencer (made by Cheesemans) and Danny has one of Ammos silencers and we've both been thrown off various trackdays (including Donnington and Bedford autodrome). As Ammo says the Duratec exhaustr seems very quiet, however you will suffer from induction noise issues if you have a bonnet cut out (as most do) so you'll need to budget for an airbox. cheers R400 Duratec Build and Modification Pictures here Link to comment Share on other sites More sharing options...
AMMO Posted June 11, 2005 Share Posted June 11, 2005 Hmmmmmmm. didn't realise you had been chucked off track days. Maybe a well designed, affordable airbox should be on the cards. Maybe that is also the reason that Caterham have opted for a short induction system on the CSR 260 to keep everything under the bonnet. I'm sure this is damaging torque through the length and possibly power because of heat. A better solution is required. Watch this space.

Ross_H Posted June 11, 2005 Author Share Posted June 11, 2005 if i have one it's GOT to get on trackdays without any issues. I think you may need to keep the inlet gubbins under the bonnet and maybe use some sort of reverie type solution ala my blackbird... If there's another solution Ammo, i'm sure ther'll be a big market for it. If you could get reasonably powerful caterham relaibly under 98dba that would be a mega selling point. Especially if you could spend 10 mins putting on a loud pipe and removing some induction kit and make it noisy for the road! Link to comment Share on other sites More sharing options...
rgrigsby Posted June 11, 2005 Share Posted June 11, 2005 Ross I guess it depends how mad you go with the cams, my 256bhp 2.3l Duratec is really not loud at all but it's only on 268 Cams, I'm guessing with madder cams it will get a bit louder. I've got the Raceline DTH throttle bodies with 90mm trumpets and a Piper X filter. Rob G www.SpeedySeven.com Link to comment Share on other sites More sharing options...
Blackbirdman Posted June 12, 2005 Share Posted June 12, 2005 Ross, If you do go the convertion route please contact me about the BB bits. However I also think this is a mad option Having recently driven AMMO's car and allowing for the fact that it still needs set up work it is VERY different from a 'bird. A great road car but...
