I know that the recirc are generally better but I was just wondering about atmospheric, as in which holds the best, which sounds the best and which is the best overall?

 

Well, this thread is probably going to get closed in no time for all the obvious reasons. But to answer your question, Tial has been known to produce some of the best vent to atmosphere blow-off valves available. Just about every big evo shop uses them on their very own shop cars.

 

If hearing the sound of a bov is worth ****ty gas mileage, inconsistent let off, and overall a ****ty ride, its for you!

Btw, I run a full VTA bov

 

keep it stock. add an intake if you need to hear the BOV "swoosh", the stock BOV is more than capable of holding boost on a moderately modified evo.

Tial if you absolutely must have an atmospheric BOV

 

i have a tial it works great no promblems at all

 

x2.. stock maf with a tial.. runs awesome.. no issues.
