A ruptured vaccum line going into boost control soleniod, bad leak at turbo inlet coupler, and BOV leak... Fixed all leaks besides BOV and car pulls much harder, and my idle isn't messed up anymore... So moral of the story do a boost leak check every now and then...

 

Glad you got your issues figured out. How are those cams working out for you?

 

Glad to hear that you got it taken care of! I think Im in the same boat... Gonna find out how bad it is tomorrow...

 

Excellent, thanks Billy, car pulls much harder up top now...but harder now that the boost leaks are fixed...

 

Can't wait to see your hp increase.

 

question: are you checking a gage while you perform the test??? if so does air leak while testing the system...or lets say you put to 20 psi..it will hold there until you manually release pressure

 

why do you think my car wants to die like i'm leaking vacumn or something .. happens when i've been driving for a while and come to stop press the clutch and the idle drops lower than normal and vacumn shows -14 instead of -16

 

Yes I am using the mechanical boost gauge in the car, charge system to 20 psi, and on my car it bled of slowly...

 

how easy is it to do a boost leak test and what kind of pump do you have to use?

 

First question... do you have a VTA BOV? That would explain the idle dip when coming ot a stop...

 

basically you are disc. the intake and hose from turbo inlet....and u connect your tester to the 2" inlet pipe(stock)

cap off any mbc and crankcase

and shoot it wit some air!..usin compressor most likely

 

I got a 3" PVC threaded coupler and a threaded plug, epoxied the plug in and drilled a hole into the end of the plug and inserted a valve stem into the hole. I recommend using a bolt/screw in type valve stem... then took off the MAF and installed it in my intake tube as it is easier to get to than my turbo inlet... Make sure to cap of MBC, and Crankcase as mentioned previously...

 

yup, this works too.....i just didn't want to pressurize my intake tube seeing as it will never be anyway and wasn't to trusthworthy of stock clamp on inlet...

 

what kind of bov are you running?? i had the stock 8 plastic bs and it leaked immediately when air ran threw....9 dv holds well

 

my vacuum is at -35 at idle, is that good or bad or average. i have stock evo mr w/ the mitsu gauges
