Mount BOV after/before intercooler? I have the STS turbo on my 99 camaro SS and will be installing an intercooler in a couple of days. It already has the BOV just before the MAF sensor and I want to know if I should have the BOV before the intercooler or after? I would normally assume after but I'm not 100% sure.
Thanks

The closer to the throttle body the better. That way it doesn't have a delay having to fill up the area after the BOV left by the zero pressure the engine intake created. So basically you'll have negative pressure behind the BOV, limiting this amount of space will increase responsiveness between shifts.

Aye, I would put it after the IC especially if there is any significant amount of resistance. Also make sure to relocate your wastegate tap after the IC, too, for the same reason. Lots of folks have installed IC's and noticed a large drop in pressure at the manifold due to pressure drop from internal resistance and dense, cooler air.
