boost gauge readings.. help.. - D Turbo Lyle - 12-05-2014 hey guys just got a 2nd hand boost gauge fitted into my pug.. the pipe from my boost gauge to the t piece is 3mm diameter inside and the t-piece(8mm/4mm/8mm) which is in the pipe leading from the pump to the middle of the intercooler. All that seems to work fine no air leaks seemingly. When i start the car the boost gauge sits at -8 or 8 below 0psi.. when its on full boost id say im gettin 11psi max.. the car is completely standard minus a backbox and middle section but has a cat.. any help on determining if this is normal would help thanks! also its a 1999 ph2 D Turbo running on a lucas and i havent even checked the model of turbo yet haha RE: boost gauge readings.. help.. - philpemberton94 - 13-05-2014 I think 11 psi is probably about normal on a standard one, if anything a little bit low, not sure why it would be pulling a vacuum though as that is the pipe that i have tapped into and mine has no problems! RE: boost gauge readings.. help.. - Piggy - 13-05-2014 You shouldnt get any vaccuum on the line at all. Is it a cheap gauge? And standard is about 13-14psi RE: boost gauge readings.. help.. - graebob - 13-05-2014 That's the line I tapped as well, and I'm not registering a vacuum, though my mechanical gauge does get a bit of flutter at idle. At stock mine is running 0.9-0.95 bar so about 12-14PSI, so you're not too far off really. RE: boost gauge readings.. help.. - D Turbo Lyle - 13-05-2014 thanks for helping guys. Ok so its a mechanical boost gauge it isnt brand new prob a few yrs old sitting in my pals shed! It seems to be sitting at -8 below 0psi when its unplugged and even if its idleing its sitting at -7,-6 ish psi. as soon as its almost getin onto the turbo it whips up 0psi and if i put some foot down am getting 11psi when on full boost. Maybe i should just get myself and new mechanical boost gauge or a digital one. Nothing to worry about but the boost gauge then...?? cheers for any help greatly appretiated RE: boost gauge readings.. help.. - Piggy - 13-05-2014 Just get another one. It should sit at 0psi at idle RE: boost gauge readings.. help.. - D Turbo Lyle - 13-05-2014 (13-05-2014, 05:58 PM)Piggy Wrote: Just get another one. cheers piggy.. looks like al be buying another 1 tonight oh well looks like my mate will be getting that 1 back... thru his window haha RE: boost gauge readings.. help.. - Mattcheese31 - 13-05-2014 yeah sounds fcuked tbh . . RE: boost gauge readings.. help.. - D Turbo Lyle - 14-05-2014 ordered a new mechanical one so hopefully that fixes that! Ill be back with different reading at weekend.. thanks all that helped a MASSIVE noob RE: boost gauge readings.. help.. - graebob - 14-05-2014 Haha I'm a noob too dude Good luck, let us know if it works out RE: boost gauge readings.. help.. - DarkInferno - 15-05-2014 Erm. Just having a thought here but if it reads 0 when it's turned off I can't really understand how it could be the gauge. A blocked air filter might make the engine draw a vacuum? RE: boost gauge readings.. help.. - D Turbo Lyle - 16-05-2014 UPDATE! Ordered and fitted a new gauge, works fine! its sitting at 0psi and full boost seems to be 14/13psi. Turns out the old boost gauge i fitted before hand was totally wrecked and sits at -8psi even when turned off.. must have been messed up internally somehow Thanks again for helping all |
