dpstarion88 Posted November 15, 2013 Report Share Posted November 15, 2013 What is this part and where does the rubber hose connect to? I have it on my '88 Starion, but the hose is missing. I tried lookin in the FSM and can't find it.?? -Dave Link to comment Share on other sites More sharing options...
19cturbo Posted November 15, 2013 Report Share Posted November 15, 2013 its basically an air bypass, but the hose just directs the air back into the turbo.. Link to comment Share on other sites More sharing options...
dpstarion88 Posted November 15, 2013 Author Report Share Posted November 15, 2013 19c, do you know under what conditions it would bypass and where exactly it plumbs into the turbo? -Dave Link to comment Share on other sites More sharing options...
19cturbo Posted November 15, 2013 Report Share Posted November 15, 2013 it should go to the bottom of the intake hose on the turbo, those were only on later model cars, 88-89 87's dont have them. they were set from the factory to let a "set" amout of air bypass the air flow sensor.. im not sure what the reasoning was.. i have seen them ran on early model cars though and just left the hose off and they functioned just fine..

dpstarion88 Posted November 15, 2013 Author Report Share Posted November 15, 2013 Hmm, interesting. It is possible that this might not be original to my car. There was soo much ghetto riggin done on my car it was ridiculous. haha I fixed most of the ghettoness. I'm thinkin this might be something that some previous owner had swapped out for whatever reason. The car does run fine with no hose attached to it and open to atmosphere. -Dave Link to comment Share on other sites More sharing options...
ColdScrip Posted November 15, 2013 Report Share Posted November 15, 2013 The reason is because it will allow you to slightly tune the amount of fuel being used. Link to comment Share on other sites More sharing options...
dpstarion88 Posted November 15, 2013 Author Report Share Posted November 15, 2013 Cold, how so? By being able to adjust the big cap screw on the side, allowing more or less air to bypass the maf? -Dave Link to comment Share on other sites More sharing options...
19cturbo Posted November 16, 2013 Report Share Posted November 16, 2013 cold, i read that you were not supposed to adjust it, thats why it was set then had the punch on it so you couldnt turn it.. Link to comment Share on other sites More sharing options...
ucw458 Posted November 16, 2013 Report Share Posted November 16, 2013 It was the factories way of fine tuning the amount of air the ECU thinks is going into the engine. The small amount of bypass corrected the air/fuel mixture so it would pass emissions. Link to comment Share on other sites More sharing options...
scott87star Posted November 16, 2013 Report Share Posted November 16, 2013 87's dont have them There is one on my 87 flatty, and they cannot be adjusted. Link to comment Share on other sites More sharing options...
dpstarion88 Posted November 16, 2013 Author Report Share Posted November 16, 2013 I'm sure it had to have been swapped out at sometime on my car. The accordion hose that is on my car had the port for the oil separator top hose/pipe sealed off on the accordion hose. As if it were never punched out by the factory. Kinda weird -Dave Link to comment Share on other sites More sharing options...
19cturbo Posted November 16, 2013 Report Share Posted November 16, 2013 There is one on my 87 flatty, and they cannot be adjusted. i stand corrected..i thought they were only for later models.. Link to comment Share on other sites More sharing options...
dpstarion88 Posted November 16, 2013 Author Report Share Posted November 16, 2013 You can see here in this pic how there isn't any hose off that little valve and vented to atmosphere. Also you can see how the hose/pipe isn't all the way in the accordion hose. -Dave Link to comment Share on other sites More sharing options...
