Quick question. I currently have a 2009 recirculating blow off valve on my Evo 8 with a hallman pro mbc. I'm gonna be putting in 272 cams, bigger injectors, pump and speed density tune for pump 93 and E85. I'm at 21.5 psi now on current tune. Do I need another bov to hold more psi with the mbc with my new tune coming. If so what should I get?

 

2009 blow off valve? Do you mean you have an Evo 8 BOV or and Evo 9 BOV, or neither?

 

If you don't want some fancy sound fx then stick with the stock metal pov. It's good enough for your current boost level.

 

I have a evo 8 with a evo 9 one on it. Just want to make sure it can hold enough

 

i have same mods and same evo 9 bov.boostin 27psi you'll be fine.

 

if you want to upgrade get the tial qr

 

Ok thanks.

 

Yeh if you are going to boost over 25-27 then turbosmart or Tial would be the best choice, but if you are going to stay under 25psi then evo9 metal bov is the best.

 

GReddy Type-S .... That's what Brian O'connor runs.

 

I'm running 31 psi on a crushed 9

If I ever need more ill go with a synapse

 

+1 on the synapse from me.

 

I use the type s. getting a uicp flanged for a greddy is a pita though

 

Awesome! He better be careful though or he'll blow the welds on the intake manifold

 

My tial held 47 lbs last night

 

Tial..
