    Mum's 94 Passat Estate

    Right, being the kind son I am Mum went away on holiday for a week so decided to change her brake fluid as she has been complaining about bad pedal feel for 6 months now. I was then asked to service her car at the same time, fine. Then finally she decided to do the front discs and pads too...

    Anyway, she's complained about the lack of power in the car for ages, so what's the easiest way to get another 20 or so ponies out of an AAZ?

    That's a very nice gesture and we had the 'scotsman' up at the steelworks the tuther week. Absolutely stunning piece of history.

    I've been about three times when I was a nipper, but haven't been to the new place they have. It's on the to do list this summer once the girls have broke up and the Jorvik centre.....if it's dried out yet!

    Welding man has come to have a look and says work begins in two weeks, he's not one to be rushed lol.

    There's a reason he became a Plumber Dirtbox

    Has this turned into a English exam or are we going to find out how we get more power

    How easy do you reckon it'll be to convince my dad to come pick up a donor from Northumberland?

    I reckon I'll find out how to make some more power by about Wednesday lunch time

    Depending on the turbo setup, you can adjust the actuator rod (make it 4 turns longer) or fit a non bleed type boost controller (preferred method and only option if there's no actuator rod) the 17.99 one on ebay from mumby developments works just fine.

    Set the boost to around 15 psi

    Add some more fuel with the fuel screw on the pump - there are more mods such as the gov mod (see 'how to' section)but the fuel screw and extra boost will give a large increase in poke of about 30 - 40% more torque and power.

    You'll need to turn the idle back down - I can send you a guide.

    30-40% is easily enough of a gain. I shall investigate the actuator and see what I can see.

    If you could send the guide over that would be grand.

    Is an EGR delete well worth doing?

    Thanks Reg!

    Yes - do the EGR, there are small power gains from not feeding the engine hot air, and bigger gains from not clogging up the intake with thick sooty deposits.

    PM your email and I'll send the guide.

    You may not have the actuator rod on your turbo, often the whole lot is integrated into the turbo housing and you need to interupt the rubber hose that sends the boost signal to the actuator and trick it into opening at a higher pressure - this is where the boost controller comes in. You may find a rubber hose which makes things easy or more commonly a hard steel line which needs to be cut so you can tap in and fit the boost controller.

    Boost controller is a sprung loaded loaded valve which opens when it gets to a pressure determined by the screw adjuster which applies a variable force to the spring, once the spring is overcome and the valve opens the actuator receives a boost pressure and opens the wastegate on the turbo, which stops the boost increasing any further.
