Hi i have a evo 9 with bunch of mods but the important ones for the question is new fp hta green tuned for 93 and in warmer weathrr for E85. Boost is at 32 psi. My question is i am running a stock Bov and do i need to upgrade my Bov and would Synapse be the best choice? Thank you in advance

 

yes at that boost pressure i would upgrade the bov. From what ive learned evo 9 bov hold 23-25 psi if you crush it it can hold more though! i would just get the one you stated and not deal with the problems

 

well synaps did not work out so i might be buying Tial. Would anybody have anything negative to say about Tial bov?

 

With the APS going bye-bye this one seems to be the new hotness: https://www.evolutionm.net/forums/se...-cobb-bpv.html

I trust Chad's opinion quite highly so it's at least worth a look. Synapse also makes a smaller unit called the DV that might be a nice choice. That Synchronic is just too big IMO, doesn't fit well with a lot of setups.

 

thank you guys for your opinions. Since i should upgrade it and adventuly i will run more boost my concern is will the Tial bov leak or has anybody had any problems with it. I am not thw type that is geating it for the loud PSHHHHHH. Also i am buying it used since it will keep couple bucks in my pocket.

 

is there a tial bov for the evo x or anything that sounds about the same?

i have synapse DV one. no issue at all. i have researched for a while in order my turbo to avoid flutter. finally I got DV one and happy with that.

 

I am going to go with synaps too
