DAWES FAQ
=========
The Dawes manual boost controller is a ball-spring device which costs about £35 in the UK and can give decent improvements in performance. It can be fitted in minutes with no tools required except maybe scissors. The main benefits are dramatic improvements in turbo spool up time, as well as a wider boost and torque curve - the effects of this can be quite considerable. However, if you push it too far so could the safety implications - if you are foolish you could lose your engine. In fitting any performance device to your car you should know what you are doing and if in any doubt consult a professional.
Documented experience on Scoobynet seems greatest with the MY99/00 UK models, and up to fuel cut (approx 17 PSI) most cars seem to cope well with fuelling and timing, although data in track conditions has not been collected. A boost gauge and air fuel ratio meter should be considered ESSENTIAL when fitting a Dawes. You need to also consider fuel cut, compressor efficiency, intercooler efficiency, charge temperatures, injector duty cycle, knock and exhaust gas temperatures. Bear in mind also that on part throttle there can be excessive boost on part throttle on cars with small turbos (MY98 on) which can affect driveability, control on bends, as well as cause lean running of your engine with potentially serious conequences.
Despite these issues, you will see from the threads below that many have worked ways around these limitations and are using the devices safely. Scoobynet, myself, Dawes suppliers or any of the posters in the below links/threads will not be liable for any personal injury or engine damage caused by any of your modifications.
Safety first!

Get rid of the fuel cut. Its too low anyway. I spent a whole year with 20ish psi on my MY93 with no detrimental effects (apart from petrol). As long as you monitor fueling, temperature etc, you'd find that its feasable.
ps, on the older car, are you still using the original boost solenoid? If you are, bypass it and connect the turbo nipple to the Dawes directly to the wastegate actuator.
edit: If only you live closer to me, I'd take a look at it for you.

Seems more like your wastegate being stuck on close more than anything. The Dawes just sorta bleeds a bit of boost from the wastegate. Try to connect the turbo nipple directly to the wastegate actuator. It should read around 0.7 Bar I think. If it does give this reading, then you might have a leak somewhere in the system while you were installing the dawes. Try this for now.

I have had a look through loads of Dawes postings and no-one has mentioned its effect on Warrantees. Can the thing be easily removed within a few moments whilst at the roadside billowing smoke ?? or whilst in for a service ?
Can it be put on in such a way that its removed
easily and exchanged for a bit of pipe or something ?
Cheers, Colin....

Nice one....
One other question.
If you put the Dawes on a MY99 with NO other mods and slowly unwind and test it, why would I need a Boost Guage ?
Do you only need a boost guage if the Fuel Cut has been altered ?
Cheers again,
Colin....

Whilst punting this very helpful thread back to the top where it belongs i'll ask a question i've yet to find an answer to.
Being unmechanically minded how do you explain it to an insure company? I've never fitted a performance mod before, do they ask what it is and what it does? And don't they want it fitted by a mechanic?

I just told them I was fitting a manual boost controller and would be raising boost from 1.0bar to 1.1bar and they said they'd add it for free

P.S. That *was* Greenlight though and they are not your average broker.....
