View Full Version : boost gauge raddle problems

06-10-2007, 07:07 PM
ive done a pressure test on my car and i have no leaks at 25psi, i have a awe centervent boost gauge and it raddles at idle between 2-3psi and under boost the needle fluctuates beetween 3-4psi, its never steady, ive switched boost gauges with my friend who also has a awe gauge and the same thing happens to his gauge in my car and my gauge works fine in his car, i had a boost leak a couple months ago on my 2871elim setup and i was running like 32psi for 2-3days days(a little past the last red bar on the awe gauge)i thought i broke the spring in the gauge or something until i switched with my friend. I now have atp gt3071 hardware kit and the problem is still there like i figured it would be? has anyone had this problem before? i will post a video up if needed tomorrow on streetfire and link it on this post? thanks for any help.....

its the gauge buzz that ur talkin about i think... u can get one of those tractor fuel filters and splice it into ur vac line and it should get rid of it

Just bring in a sample of your vacuum line size to Napa and ask them where their mini in line fuel filters are... Get the one with the METAL inside... Not the paper filter, the paper didn't work on mine and I got the metal one with no problems for about 5 years now!

ok i got a little red tractor fuel filter from advance auto parts with a metal screen inside(its a 1/4 inch filter, the boost line is smaller than 1/4inch so i had to strech it but its on there) and put it on the boost line right above to the plastic T that goes into the FPR and intake manifold, its tractor filter is about the the same size as a pcv check valve and it helped a little but still the needle jumps and the raddle noise is still there....did i get the wrong size filter, its all they had!

this is what i bought

you just have to make sure that the filter itself is metal, and not paper...
