as title states, any advise on BOV that can hold >27lbs boost?
does stock evo9 BOV hold that much boost?

 

i know the tial bov does my buddy has a supra boostin 32psi on a t67 turbo and he only has one but someone else chime in because i am still a newbie

 

Greddy Type S BOV

Been using it for three years now. Boosting 30 psi

 

Forge EVo15

 

I have an APS. Used it up to 32lbs on a GT35 and held boost perfect.

 

how about greddy type R? any input on this BOV?

 

SARD Racing BOV

HKS Racing BOV

Synapse BOV

TIAL BOV

Greddy RS BOV

etc., etc., etc.....

The SARD Racing BOV I've had up to 42psi running through it... It sounds just crazy at that boost level with it's massive ports. I suggest!

 

SARD...hmm...thanks for the input guys.

any words on Greddy Type R???

 

Be sure to get the SARD Racing and not the R2D2!!!

I have seen the Greddy Type R push 26-27psi. But nothing above 30psi.

 

Forge diverter

 

i've heard great things about the Forge DV, however a buddy of mine was forced to swap it out to a APS as the Forge unit wasn't holding boost well. he was running 30 PSI spiking down to about 27 i believe.

 

Do a search on the Forge Valve. People have had issues with both the 15 and the RS. Both hold boost great, but there are flutter issues and some purge rather violently.

If you have a standalone ECU, the TiAl is a good option. Running the stock ECU some have had good results with the dual stage valve whose name I can't remember. Mellon runs it. I have no experience with the Greddy valve.

 

That would be the APS dualport valve.

We both run it and it is great.

 

what about a crushed stock Evo IX bov?

 

i chrushed my IX vavle on the dyno and it would only hold around 28psi....

the forge i have seen 45psi held...

mine holds great...
