    Interesting discussion with Jabba about DV valves

    I was on the phone to Jabba this morning discussing tuning options for my car, and they recommended upgrading the standard diverter valve for an atmospheric version. As apparently the early cable driven cars were atmospheric [img]/ubbthreads/images/graemlins/confused.gif[/img] So I had a big discussion with him and stated that I thought they weren't, but he was adamant that they were.

    So was I correct?

    Re: Interesting discussion with Jabba about DV valves

    Surely not?

    I had a cable-driven AGU 1.8T (1999), and that was a standard OE recirculating DV.

    I didn't think there was any performance advantage to having an atmospheric dump valve on a 1.8T...

    He wasn't trying to sell you one was he? [img]/ubbthreads/images/graemlins/laugh.gif[/img]

    Re: Interesting discussion with Jabba about DV valves

    All 1.8T's came with diverter valves (recirculating DV), but you could fit an atmospheric DV to all throttle cable version without any problems. I use to run a Baileys D26 atmospheric DV on my AGU golf and it was fine.

    Forge Motorsport have now designed a fully atmospheric DV which works with both non-dbw and dbw turbo engines. I have a polished silver version for sale if anyones interested.

    Heres a link to what it looks like: http://www.forgemotorsport.co.uk/pro...roduct=FMDV004

    What a load of Bulls*it! no 1.8T have EVER been atmospheric. In fact, NO car ever comes with an atmosperic DV. the only cars to gain from this are cars with no DV whatsoever!

    Yeah I know that's why I was on the phone to him for about 15 minutes explaining why they don't run well with Atmospheric etc.., but he wasn't having any of it LOL
