Sometimes if you spent more than five minutes posting facebook and instead searched on google you might understand the World Rally Champion anti-lag system that’s used on Subaru’s rally cars.
It gets to a point were none of these people should own a turbocharged Subaru. True anti-lag systems are expensive and require extensive tuning and kills turbos which translates into a lot of money which none of these people have.
When someone first buys a turbo Subaru they are excited to modify their new toy. Often they’ll buy a exhaust, a intake, and a aftermarket blow off valve that replaces the factory BPV. Unknown to them Subaru’s often need to be tuned after even a little change like installing a intake or in this case installing a blow off valve.
If this guy took all of two seconds to type into google”Subaru blow off valve” he could have had all the answers he ever needed. Message boards like IWSTI or Nasioc have extensive stickied threads on this exact topic from people who are experts with turbo subarus.
Now he has to deal with people trolling him and people that are as clueless as he is. After a week or two he’ll probably ignore all advice and install it anyways. Two weeks after that he’ll be asking why he engine is knocking. Said person will complain that he bought this car with a loan and doesn’t have any money to get a new engine nor has the skills to build his own.
Most of the time when a stock block cracks it’s after being tortured with over 400+ horsepower through Subaru’s All Wheel Drive system. Not this case with this engine however. Instead it’s the owner being an idiot.
