want to know where to find a good 50/50 blow off valve that wont brake the bank
ive read that total atmospheric will help you loose 50 miles to a tank....and that the 50/50 is a much safer choice anybody with some input would be a great help

 

Imput: if you don't have a large turbo, don't buy a bov. You could decrease the performance of you car. That being said, I have heard the the 50/50 ssbov is the best.

 

WTF...

BOV to atm will make your car run rich. not make you loose gas miliage..

stock bov (by-pass valve) redirect the excess pressure,after the turbo and before the throttle body, back in to the intake, after the MAF and before the turbo

atmo. bov will let the air out. because MAF is not pressure based, your ecu will not know that the air is gone from the intake tract and will feed the fuel based on the MAF reading. there for you get same fuel and less air: rich condition.

unless you change your MAF with a pressure based system, like VPC, BOV is always hazardous to your engine.

that being said, theoratically if you move your MAF just before the throttle-body, you could minimize or even elimiate the rich condition

if you really want the "woosh" sound, then get a whistle and blow it every time you let go of your gas pedle.
or get an intake. seems like most people can hear the stock BPV with an intake.

 

or just do a snorkus delete = free fun ;-)

 

If you run rich, your gas mileage goes down. You got all the rest right...I'm surprised you didn't make that small step in reasoning.

 

true you'll loose gas miliage.. but not 50
