| Re: dump valve?? Pretty silly tbh as diesels dont need them. You cant fit a regular dump valve, you would have to spend circa £300 on an electically activated one. |

| Re: dump valve?? Something like this will give the effect of a dump valve on a diesel (i.e. the sound): You'll need both IIRC: http://www.forgemotorsport.co.uk/con...&product=FMDDV and http://www.forgemotorsport.co.uk/con...duct=FMDFKVW13 Please note I'd check the latter as it doesn't mention the Fabia vRS etc.. Looking at a fairly costly bit of kit for zero benefit though, 300-ish quid.

| Re: dump valve?? I have a dump valve fitted to my Furby VRS, i bought mine from The Derv Doctor and fitted it myself. In my opinion i think it sound pretty good, my car is running around 24psi, so there is alot of pressure to get rid of. As for performance, not sure, not really engine minded.

| Briskodian  | Re: dump valve?? All PD diesels engines have VNT (Variable Vane Tchnology) As used by Porsche on their New 997 Turbo, and so have no need for a dump valve, as the main reason for a dump valve is to get rid of excess boost to stop the turbo stalling when you get back on the gas again! IRC a VNT Turbo adjusts the pitch of it's blades to stop turbo stall and is thus more efficent! If you want a Woosh..Pshhhht noise everytime you change up buy a scooby! Just my Humble 2ps worth! Personally I would rather spend £300 on a remap or some decent suspension, but each to their own LOL Steve

| Briskodian  | Re: dump valve?? Diesel dump valve, lol I had the hydrahulic suspension on my non turbocharced BX diesel. The pump often made a psschtt noise .Can't say I can see any reason for a dump valve, i'd definately save it for something else. A faster remapped car is surely much more impressive that it making a noise. EDIT: I've just watched the two videos, that 306 1.9TD sounded bloody awful. I had one of those and I can tell you that fitting a K&N induction kit as was done to a friends by me as I had the tools makes a far more impressive noise Last edited by cheezemonkhai; 19-04-2006 at 23:38. |
