MarineIguana Posted August 11, 2010 Share Posted August 11, 2010 Right my car seems to have no boost the reading on the boost gauge never goes past the 0 in to boost and I have never heard the dump valve go off so I assume there is no boost, I know the wastegate can move freely and the flap is still in there and I have a new actuator, and there are no leaks from any pipes. I can spin the turbo by hand and it's ok no play, So I am lost to why there is none I don't want to wind the actuator in anymore Stupid crap cab Quote Link to comment Share on other sites More sharing options...
MarineIguana Posted August 12, 2010 Author Share Posted August 12, 2010 Right tested it with the AMAL valve bypassed and still no boost, so gonna wind the actuator right in now Quote Link to comment Share on other sites More sharing options...
Guest KarlosG Posted August 12, 2010 Share Posted August 12, 2010 How much preload have you put on the actuator, should be set to about half a 'hole' if you get me?! By-passing the Amal valve (as in piping the actuator straight to the compressor housing) will give you less boost. With half a hole of preload and the amal plumbed in and working you should see around 7psi of boost no later than 3000rpm. Quote Link to comment Share on other sites More sharing options...
MarineIguana Posted August 12, 2010 Author Share Posted August 12, 2010 (edited) Preload I assume how much pressure is holding the flap closed ? And half a hole I would think is how far the pin for wastegate is past the hole for it on the actuator so its got a bit of force holding it closed ? I'm new to turbos lol :D What way does the flap need to be if I'm under the car looking up at it to the left or to the right as I forgot which way is closed and which is open Edited August 12, 2010 by MarineIguana Quote Link to comment Share on other sites More sharing options...
Guest KarlosG Posted August 12, 2010 Share Posted August 12, 2010 Yes mate thats spot on, the actuator keeps it closed so it sits towards that. Quote Link to comment Share on other sites More sharing options...
MarineIguana Posted August 12, 2010 Author Share Posted August 12, 2010 Right took it all off easier that way and my actuator bracket is bent I think as the rod doesn't line up well with the wastegate arm Will try and heat it up and bend it back into a better position.

Guest KarlosG Posted August 12, 2010 Share Posted August 12, 2010 If thats how you had it then you've got it stuck fully open which is why you have no boost! lol You should have to pull the actuator rod out to get it on the wastegate arm by half a hole, looks like you've been pushing it in to get it on?!

MarineIguana Posted August 12, 2010 Author Share Posted August 12, 2010 (edited) Awesome I just been messing with it to be honest wound it all the way in see how much the alignment is out by Edited August 12, 2010 by MarineIguana Quote Link to comment Share on other sites More sharing options...
Guest KarlosG Posted August 13, 2010 Share Posted August 13, 2010 Yeah it does look a little bent. Quote Link to comment Share on other sites More sharing options...
MarineIguana Posted August 13, 2010 Author Share Posted August 13, 2010 I give up Still no boost just sits on 0 on vacuum gauge never gets into the boost just about had enough of it now Quote Link to comment Share on other sites More sharing options...
gingergman Posted August 14, 2010 Share Posted August 14, 2010 loosing patience mate? this is why im sticking to non turbo lol. poss take the full unit off and take it to a specialized garage to have a look at it? Quote Link to comment Share on other sites More sharing options...
MarineIguana Posted August 14, 2010 Author Share Posted August 14, 2010 Losing it a little bit I just don't know why its not going the car has power it's not slow but it could still be faster if the turbo did it's job properly I will get it off again and strip it right down and check the whole thing out so need to get some gaskets and have a poke about see if anything is broken or worn out, Car is definitely wearing me out but must go on with it can't give up Quote Link to comment Share on other sites More sharing options...
