    umm... It might be a bit longer than I'd hoped.

    I don't think my choice of sealant was, ideal. Evo-Stik Liquid Metal isn't as good as it says...

    Once I've got the rest of it off me and the keyboard, I'll start again with a different addhesive.

    definatly, if only because the old prototype was leaking boost pressure which this one isn't.

    Don't have a mount for the boost gauge yet but I have the bits I need.

    Also, I've been working on the dump valve and have a plan... Dump valves don't just use a spring to hold the boost in, they use apposing boost. The dump valve is plumbed in before the throttle plate and a feed comes from the other side to the top of the dump valve. The pressure feed to the top of the dump valve acts on an equal or larger surface area than the dump feed. Along with the spring, this keeps the piston closed. When the throttle plate closes the pressure drops past the plate and on petrols produce a vacume. This vacume along with the pressure on the turbo side of the throttle plate open the valve against spring force and dump the pressure.

    Now if the spring were only very weak then simply removing the pressure from the apossing side of the valve should allow it to open. I have a solenoid selector valve rated to 10 bar which in it's self could act as a dump valve (cost me £30!). I could either use this by itself, or fit it into a line to open the servo line and allow boost pressure alone to open the dump valve. Alternativly I could use two of these valves, one attached to boost pressure and the other attached to vacume. With some simple normally closed and normally open relays I could then swap between boost and vacume to operate a dump valve.

    Theroy all sorted out, now the real question, will the ECU throw a fit? I'll try it just with the normally closed solenoid valve first to see if it gets stroppy and if it works okay, I could make a kit or just tell you want you need to use on any diesel.

    As above really Nut

    You ain't gonna win any style awards though LOL!

    Can see the concept. What's your induction system like these days?

    ECU wise I would say with that dump valve system would have a dikky fit.

    Looks like this, standard air box on the left with a K&N panel filter, a second cold air feed to the panel, a line from the top of the box to a second enclosed filter with it's own cold air feed.

    All the feeds face into head wind so I get load of flow.
