Default fitting a dawes device

Hi i am looking for someone in the northwest who could help me out in fitting a dawes device. I believe it is an easy fit but i would sooner let someone who knows how to do it do it.

i would be gratefull if there is someone out there who could help me. i would be willing to pay for the services.

cheers

Helpful thread here:-

NOTE: the 90-deg outlet end of the DD goes to the wastegate actuator... and the straight outlet end to compressor nipple

we've all been there, me included, someone will help you out up there but if not plenty of advise on hear if you need it...simple to fit just dont go silly with the boost. i fitted one to lower my boost as it was spiking up to fuel cut level and dropping back in high gears but had it remapped since

right i purchased one of these and have just TRIED to fit it, i did everything described on here and also on the website for the dawes device BUT something just didnt seem right, it was boostint up to 1bar but didnt seem to have that "kick" that i had prior to fitting. i have obviously done something wrong and as a result have now removed the device and gone back to standard boost as i do not want to damage my car. so i ask again is there ANYONE in the northwest who would be willing to come and fit this for me. as before i would gladly pay for their services.

Did you do an ECU reset before driving, after fitting it? Prob not required, but still a good idea to start afresh with a 'clean canvas', so to speak.

Did you fit it with the 90deg elbow end at the wastegate end? Did you not experiment winding the nut in more, etc.?

didnt do an ecu re-set as didnt think it was needed and if truth be known i dont know how haha
i did fit the wastegate end on the elbow and did wind the nut in, almost to the point that it was fully wound in!!!
im so anoyed with my self as it seems sooooooo easy to do when you read up on it.

am i right in thinking i remove the pipe off the waste gate then block it of. then fit a short as possible pipe to the device elbow and the wastegate? (that part i think i got right)
then i get the pipe that is joined together with a plastic "T" type coupling (it is wider on one side than it is the other. split the pipe attached the one that is fitted to the turbo to the other end of the device and block the other peice off?

or ami missing something?

MY96 "phase 1" (coilpacks on plugs)?
or
MY97 "phase 1.5" (coilpack module on centre of inlet manfold)?

Well, if it is a MY97 then, if I'm right in my thinking, it has the 2-port BCS. This set-up means you have the little brass boost-control restrictor pill in the small bit of vac line between turbo compressor nipple and that plastic T-piece (prior to fitting the DD). If the pill is still there (or not), then I don't know whether this prevents the DD form working properly(?)

Hopefully someome will point you in the right direction on this issue...

See the below diagrams for how your BC system is plumbed together (prior to fittng a DD):_

Do you have a cameraphone or proper digital camera? Is there any chance of posting a pic up of your car's BCS to see if it's a 3-port... or indeed the 2-port like the one above? Well the 2-port won't look like that one in the pic... it'll look eactly like the OEM 3-port, BUT with the 3rd port at the vey bottom omitted. lol

Oh okay, in that case - at least, the way I understand it - is the pill don't come into it as it's in the vac pipe fitted to the bottom, '3rd port' of the 3-port BCS.



The DD basically replaces the 3-port wholesale, by plumbing direct between comp nipple and wastegate connections (see above).

I don't think there should be any plastic T-piece in the 3-port set-up either, unless it's there for a boost gauge, of course. But you'd normally have a boost gauge's reference coming directly from the manifold (or certainly after the TB) as, measured there, it's the true boost level going into the engine (i.e. there is a small pressure drop after the IC).

yeah that's the one I got. And you are correct I do not have a t piece I do have a plastic connector that joins two pipes together (one is wider than the other)

Oh right, that's okay... although do you reckon the difference in the bore of those vac pipes could be adversely affecting the boost, hence you only getting 1.0bar when wound right in?

BTW, your UK car's OEM boost is only 0.7bar, so you really only ought to be running upto 0.9bar... or 1.0bar at the very max! IMHO.

Yeah that's what I mean! lol.



But you're concerned it deosn't feel faster, right? Could this not just simply be Placebo Effect?! (because you've done a go-faster mod and would understandibly be 'anxious' that it's working correctly!).

After all, unless faulty, the gauge won't be lying!

No it is running 1 bar without the DD on. so I think it may be wise to not bother putting it on. After all I'm just being greedy right? LOL.

What's making it run at 1.0bar without the DD then?! As said, OEM boost should be 0.7bar anyway!

Laugh.

I was gonna say the decat could be promoting boost creep (hence the 1bar)... BUT... it now seems to be back to 'normal', regardless!

Now's the time to refit the DD. Make sure it's initially wound out (low boost), then little by little repeatedly wind in/test drive... until you get the gauge to hold 0.9 - or 1.0bar (your choice)...
