coopertrooper2001 Posted December 2, 2004 Share Posted December 2, 2004 Another question about the Caterham Im afraid. Standard Superlight running a K-Series with 5k on the clock. When the car is idling at 1200-1400 RPM from cold it is fine, but when it gets warm and idles around 900-1000 RPM it almost sounds like its hunting. The potentiometer was replaced before delivery was taken but it still doesnt sound right. I know its running an uprated cam but just doesnt seem right. Also when you take your foot off the clutch and idle there is a strange whirring almost a grating noise, clutch in noise gone. CRB? Idler gear, drop gears?

F355GTS Posted December 2, 2004 Share Posted December 2, 2004 CT Gearbox noise sounds like the layshaft and TADTS You say std Superlight then mention an uprated cam, is this as in uprated beyond the standard Superlight Cam? Mark Link to comment Share on other sites More sharing options...
Support Team Shaun_E Posted December 2, 2004 Support Team Share Posted December 2, 2004 As standard, Superlight is fitted with 1.6 Supersport engine. Supersport cams are a little bit lumpy, especially if timed correctly. If it really is hunting badly then there might be something wrong - best bet is to go to your local meet and listen to some other SS engines. As Mark says the gearbox noise is a standard feature .

Myles Posted December 2, 2004 Share Posted December 2, 2004 Have you checked that the IACV is plugged-in and working OK (you should be able to hear it whir when you turn the ignition on and off - after a short delay (IIRC - haven't driven my car for over a month now!) When I picked up my s/h 7 last year, the idle was pants - and hunting - the IACV had been unplugged for some reason. Project Scope-Creep is underway...
