i need some help from you turbo guys...
my vacuum is at 8 instead of 20 and my bov wont blow off till HARD acceleration... and it wont boost till like 6k rpm.. i feel something is wrong and in eed your guys help. checked vacuum lines and charge pipes seems fine but i dont get it

TIA

 

more than likely is a charge pipe and a vacuum line it seems. The gauge should be reading 20, that suggests a vacuum line, and also since you aren't building boost, that kinda means charge pipe. Not sure what else to suggest.

 

would it be ok to drive around like ethat? or do i have to fix that problem asap???

 

i would try and fix it asap, you can possibly overspin the turbo

 

does your idle surge? if its reading such a low vacuum pressure i would assume theres a noticable leak. check all the T's and connections, and the fitting that goes into the boost guage. and if you cant build boost, i cant think of anything aside from a coupler being lose, or some tiny pinholes in the welds.

 

thanks guys ill check up on the connectors... but as far as the t fittings and vacuums i checked them all they look good to me

 

your BOV should have its own vacuum source, BOV and wastegate should always have there own source, ( if the WG isnt hooked up to the compressor housing )

 

naw my wastegate is hooked up the intake manifold and so is the bov... also the wierd thing is that before my type s sounds sharp, kinda laser like sound but now it has this wooooooooosh with a echo... would having a loose chargepipe of vacuum leak cause the bov to sound like that

 

i used to have a type S bov, and when i would let off the gas it would have the same swoosh sound unless i was boosting over 6psi. every bov will sound diff on diff peoples cars, why? i dont know..but its something i have noticed. just check over all the connection, check the back of the boost guage..thats one place people always forget to look

 

thanks
