Anthony Posted November 22, 2005 Author Share Posted November 22, 2005 Just realised what astonishing value this is in comparison with built in systems Simon has first dibs subject to it fitting his Duratec. Anthony Link to comment Share on other sites More sharing options...
MikeE Posted November 23, 2005 Share Posted November 23, 2005 it won't fit his duratec without a customer back plate. I suggest he talks to Peter T about the supply of a custom Duratec backplate.....

Peter T Posted November 23, 2005 Share Posted November 23, 2005 Yes Mike it would include internal air filter. And yes i could help with the backplate solution. Carbon Components Here K9 Composites Link to comment Share on other sites More sharing options...
Anthony Posted November 23, 2005 Author Share Posted November 23, 2005 Guys, yes it includes an ITG filter. Thanks Pete, wish I had got the airbox modded now 😬 Ammo and EFA have suggested it will fit straight on (backplate would need to be cut to match duratec of course ) Thanks Link to comment Share on other sites More sharing options...
EFA Posted November 23, 2005 Share Posted November 23, 2005 Just a thought, but if the spacing between the roller barrels is the same as on a K (it quite possible is to get the common linkage working) then one of the pre-cut R3/4/500 backplates should fit a Dura with Caterham Roller B's. The only special backplate made was a dished one which allows it to be fitted with the overhanging fuel rail the 8 injector Jenvey setup on my car has, and also the Jenvey DTH bodies for the Zetec I believe.

Gambo Posted November 23, 2005 Share Posted November 23, 2005 *thumbup*It really is a very nice piece of kit. Shame it would not fit mine. At £500 nicker it is cheap compared with reverie. Which at the mo is the only thing I can find to fit my VX. ☹️ RED 2.0 HPC now on throttle bodies Link to comment Share on other sites More sharing options...
MikeE Posted November 23, 2005 Share Posted November 23, 2005 Arnie, Peter T and I spent a good hour or so working out how to fit one of these airboxes to a Duratec (mine) one day last winter (after I'd helped him move his hot tub 😬). With a flat back plate the airbox is in danger of being hit by the nearside front wheel on full lock. In a K-series (and VX I presume) the engine is canted over (to allow the induction to fit within the confines of the bonnet) and this has the effect of tilting the airbox upwards. On a Duratec the engine's mounted vertically so the induction/airbox is horizontal and therefore much closer to the front mudguard. So the solution is actually to make a 'Duratec backplate' which tilts the airbox up at 20deg or so - yout won't do it with a flat backplate. Having said that I have the Raceline (Jenvey) throttle bodies, with roller barrels their might be more clearance but I'd be surprised if there's enough.

EFA Posted November 23, 2005 Share Posted November 23, 2005 MIke, The VX is also absolute vertical in the chassis. What TB's is your Duratec using, and is their axis up the tracts perpendicular to the engines vertical centreline? I think an angled backplate will interefere with the airflow around the trumpet mouths if you are using very long and l;arge dia trumpets (mine are 105mm dia, 110mm long) Edited by - EFA on 23 Nov 2005 23:58:09 Link to comment Share on other sites More sharing options...
Anthony Posted November 24, 2005 Author Share Posted November 24, 2005 Guys, agree on the box being first class, it really is beautiful. My induction exits horizontal to a vertical engine, on reflection I should have had an alternative backplate made up. Alternatives are expensive, in some instances four times the asking price. What I have learnt, a bit too late, is not to be put off if something does fit, a professional solution can be made to match the performance and appearance of the original. Thanks for all your help.

MikeE Posted November 24, 2005 Share Posted November 24, 2005 Arnie, I think they're Jenvey 45mm? (branded Raceline) and yes I'm pretty sure they're mounted perpendicular to the engine (i.e. horizontally) so I'm a bit puzzeled how it fit's fine on yours. At the time Peter did say your had to have a modified backplate because your fuel rail was beyond the line of the backplate but I guess you still mount the backplate vertically? Do you have super-wide front suspension as I guess that would give more clearance? R400 Duratec Build and Modification Pictures here Link to comment Share on other sites More sharing options...
Anthony Posted November 24, 2005 Author Share Posted November 24, 2005 Guys Direct to head TB's / Jenvey's come off the VX head at an angle, they do not come off perpendicular, unless I am mistaken Anthony Link to comment Share on other sites More sharing options...
EFA Posted November 24, 2005 Share Posted November 24, 2005 Mike, There is a pic of how my and most of the DTH type TB's fit onto a VX. My TB's are actually 25mm longer than almost all others on a VX, and the backplate of the airbox is a dished type to prevnet the airbox interfering with the top fuel rail. Only VX's on carbs, or VX's using 45DCOE type throttle bodies (like JPE's had) on the original Caterham VX inlet manifold have the inlet tract horizontal. This actually meanms there is quite a pronounced kink in the inlet tract which has a detrimental effect on power.

MikeE Posted November 24, 2005 Share Posted November 24, 2005 I can't access your picture Arnie Take a look here, clearly I was wrong the Duratec DTHTB are infact angled upwards slightly. Surely your's must be angled up even more though otherwise you'd have the same problem I had?
