Thorin Posted August 15, 2002 Share Posted August 15, 2002 Got my boost gauge today but not had time to actually fit it in the dash yet. I did have a play and connected up following the guide and pictures on http://www.mkiv.com and I'm pretty sure I connected it up to the correct pipe. However at idle the gauge read something like -0.7 bar Have I connected it up wrong or do I need to insert this small metal piece that is supplied to go into the end of the T-piece section (doesn't look like it's designed to come out very easily once it's in there!). Also, on mkiv.com it says to feed the vac hose through the grommet near the clutch pedal but with the yank supra having it's steering wheel on the wrong side I'm not sure where abouts this is on a J spec. Help! Quote Link to comment Share on other sites More sharing options...
Thorin Posted August 15, 2002 Author Share Posted August 15, 2002 ok ignore my newbie ramblings. Having never owned a turbo'd car before I'd just assumed it would be at 0 on idle. Also I'd misread the mkiv.com article, it actually says that "at light throttle 0 psi" not at idle. but where abouts is that grommet on a j-spec? gonna have a proper look tomorrow if I get chance...

MONKEYmark Posted August 15, 2002 Share Posted August 15, 2002 you cant miss it its a big black rubber grommet a bit bigger than a 50 pence peice on the bulkhead (think thats what you call it) i cut a small slit in mine and put my cables through it. is your boost gauge an electronic one or mechanical one with vac hose in the back of boost gauge easy to fit once you know how.i put my boost gauge in left air vent and egt i in right air vent have fun Quote Link to comment Share on other sites More sharing options...
Thorin Posted August 15, 2002 Author Share Posted August 15, 2002 It's a mechanical one (one of the new HKS Direct Bright ones). IS this grommet in the drivers side footwell then? where abouts exactly? (Yes I know I'm lazy, I'll have a proper look tomorrow). Quote Link to comment Share on other sites More sharing options...
MONKEYmark Posted August 15, 2002 Share Posted August 15, 2002 drivers side next to the brake master cylinder (big black round thing) not far from second turbo you cant miss it unless your eyes are closed Quote Link to comment Share on other sites More sharing options...
Thorin Posted August 15, 2002 Author Share Posted August 15, 2002 aaahhhh that'll be why I couldn't find it then. Quote Link to comment Share on other sites More sharing options...
Steve Cargill Posted August 15, 2002 Share Posted August 15, 2002 I think you'll find as you have a manual car that the grommit is actually filled by your clutch.... http://www.cargills.demon.co.uk/supra/mods.html#BoostGauge Quote Link to comment Share on other sites More sharing options...
