bryz Posted February 14, 2010 Share Posted February 14, 2010 hey guys. got a boost gauge plumbed into my ep91, think im on the wrong pipe as it reads the intake pressure fine but doesnt drop much when your up to speed. just wondering what pipe people are using so i can find out if the gauge is falty.

lukEp Posted February 14, 2010 Share Posted February 14, 2010 What Reading you getting tickover should be around -20 psi (vacuum) and full beans you will get 0psi equal pressure before and after the throttle body. That me presume you've got n/a. Quote Link to post Share on other sites
bryz Posted February 14, 2010 Author Share Posted February 14, 2010 doesnt go into - at all. sits at 0 then rises upto +12ish as you nail it. then if your sittin at a steady e.g 70mph, the gauge will sit at +7ish. thats why i think its reading the intake pressure and not the boost of the turbo if that makes sence Quote Link to post Share on other sites
lukEp Posted February 14, 2010 Share Posted February 14, 2010 Yeh I get ya find the fpr vac line and plumb it in to it as that comes straight from the inlet mani and has no other branches off it. Just to see if it makes a difference if it don't then I'd say if it's an electronic boost gauge it's the sensor or the guage mate or if it's machanical gauge it's shot.

federalman Posted May 16, 2010 Share Posted May 16, 2010 You have to plumb into the line coming from the inlet manifold to the blow off valve dont you? Quote Link to post Share on other sites
