Sorry for the ignorance, have obviously seen people going on abouth these for ages but have only just recently been bitten by the power bug having owned the car for nearly 2 years and now craving more power.

What does the Dawes do, how much does it cost, does it increase power and more importantly where can I get one. Would anyone recomend that I get one with the following mods already on the car:

MY96 UK turbo with Scoobysport back box, down pipe,centre section and panel filter. Hoping to add Forge Dump Valve at the end of the month.

Again, apologies, I know this has been done loads, but with no search I haven't got time to go back through 6 months of posts.

Thanks in advance for any help.

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 potential 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!

Some I-club threads - bear in mind these are based on the MY01/02, and these cars seem to behave differently to the MY99/00 UK turbos, and also UK MY01s do not seem to have the same EGT (exhaust gas temperature issues)

You can get it from Jamie Whitfield www.performanceexhaust.net the UK distributor for Dawes.

It would probably work quite well on your car.

I got a Dawes from Jamie (excellent service btw) and it has transformed my car - well worth doing.

i agree wholeheartedly-
the dawes is an excellent mod (with a bit of self control)

The key thing with these products, is you should never do any changes without having a boost gauge.

...at the very least

Thanks for all the info chaps, especially John.

Basically I need to fit a boost gauge first, does anyone know where I can get one fitted in the Hertfordshire/London area (Dawes that is - could get Scoobysport to fit a boost guage when having brakes done), can't trek all the way up to Liverpool and don't have the know how to do it myself, even with diagrams!

Cheers again.

Sorry, last post was a bit confusing, what I was trying to say is, if I ordered a Dawes, say from PerformanceExhausts, is there anyone relatively local to me to fit it.
