Is there for a blow off valve? Does the factory bypass valve not cut it when intercooled? Can it be ran returned to the intake? Or does it have to be open to atmosphere?
Could possibly be there for a dump valve (maybe somebody got sick of dealing with the stock bypass?), that or whoever had it before you wanted to be a sik kent.
Cool I'll just block it off and replace the factory bypass valve so I know it's definitely working. I've never been a fan of bovs and couldn't see anything online for roots style blowers .
