I have had a Dawes Device fitted to my MY96 WRX wagon, due to overboost problems, and therefore fitted a boost gauge in what I was told was the correct place....between the manifold and wastegate actuator. Gauge was reading 0.7 bar when I hit overboost again so obviously isn't the correct place! :(

Where is the best place to connect your boost gauge?? I was told in between the turbo and the intercooler is the best place to give accurate boost readings?? :confused:

Any suggestions??

:confused:

mine is (MY96) just next to the manifold... I'll email you a pic if u like. What boost gauge is it?

Its a TIM one....just a cheapy to give us an idea of what the boost is doing....will eventually get a decent one!

I spoke to the place I purchased it from and they said 0.7 bar was an accurate figure of how much boost would be coming out of the engine (:confused: ...I'm not mechanically minded!) and that I must have it in the wrong place. He said to put it before the engine so that I have an idea of boost going into the engine....

Piccies would be great, thank you! :D

or here. The gauge feed if just to the left of the manifold that then goes to the sender unit which is attached to the strut.

ok I've updated the photo and ringed the connection in green :cool:

Ruth - I'll be home tonight if you need any help with the dawes!

Dizzy,

Ta very much for the pictures. It's odd cos I have my boost gauge connected to the same place as you have yours....and yet I am still not getting an accurate reading of boost!! [img]images/smilies/mad.gif[/img]

:confused:

Russell,

Thanks very much for the offer of help. I only just got your message today so I couldn't call you last night!

Might need a bit of your expert advise and it would be good to meet some of the Aberdeen Scooby regulars! :cool:

Ruth

0.7 bar is exactly standard boost are you sure your overboosting? are you sure u've got your dawes on correctly? (mine is connected just to the left of my green oval ;))

Yep....positive. I had an overboost problem before due to a cracked wastegate actuator and so I recognise overboost when it happens! Spent weeks driving round the problem!! (fixed now tho! :D )

The gauge cranks up to 0.7 bar during hard acceleration...you keep accelerating and the gauge still reads 0.7....you then hit overboost (which I understand happens at about 1.2 bar??) a couple seconds later at about 3500-4000rpm....

Dawes was fitted by Scooby professionals and from your picture the boost gauge is plumbed into the right place....maybe it's just a cr*p gauge!!

Fuel cut happens @ about 1.1bar on mine.
Best bet will be to go to a meet an get some people to look and point at it :) That always fixes things :)
