Blowoff valve on intercooler instead of TB charge pipe?
Saw a couple builds lately where people had their blowoff valve welded to the intercooler instead of the charge pipe just before the throttle body. Seems like a decent idea, but I wasn't sure if there was a benefit to having the BOV closer to the TB or not. I figure either way it'll vent the pressure when the TB blade closes.
Isnt the TB charge pipe after the intercooler output and I see 95% of the cars out there with the BOV there?

95% of cars run it near the TB. Theres been alot of discussion about it but either way is fine, as long as you have one. lol
Its main purpose is to protect the turbo from back loading/pressure surge when the throttle blade is closed.. So the ideal spot would be as close to the turbo as you can get it..... because the further away from the turbo the longer you are going to take to release the pressure from it.... but its milliseconds... and i guess in the right circumstances thats all it takes to mess something up. You have to remember the turbo is spinning thousands of rpms, and then suddenly close the TB.... after the intercooler would be even worse. In the short time the pressure before the IC will build.... Milliseconds I know.. but why not do it right?
I think people think that they need to put it near the TB because that is what actuates it.
Mine is on the charge pipe coming right out of the turbo....because protecting the turbo is why I baught it.... not to sound like a ricer and be cool.
Its purpose has nothing to do with the TB.
If you are going to put it on the IC, definately the inlet side, because the restriction of the IC will delay the pressure release on the other side....thus putting the turbo in potential danger. (most will never matter, its so minute...maybe in a high boost application it would matter more.??)
