inconsistant boost???
Posted: Mon Dec 12, 2005 4:14 pm
a few weeks ago i borrowed a boost guage off a mate to see what i was boosting. Generally the boost goes up to 8lb and stays there but i found that sometime(albeit rarely) it goes to 9lb and stays there. As far as i'm concerned there is nothing wrong with this.
However...after getting used to how 8lb feels i've noticed(but can't confirm as i've given the gauge back) that the car seems to have lost boost! It feels along the lines of about 4/5lb max and it doesn't come on till about 4000RPM. Now last week i had my car in the shop having the oil lines replaced with braided ones and 2 days later the clamp that holds the oil/water part of the turbo(don't know what it's called) came off and everything forward of the exhaust housing came out about 2-5mm.I thought i may have damaged the turbine but sometimes the the car boosts normally??!!
anyone have any ideas what could be going on? i know you're all going to tell me to hook the boost guage up again but this is a noticable difference in boost.
