My EVO is my daily driver (live half a mile from work) and I only stomp the gas if someone wants some or I go to a rally event (SCCA). I have between 300-315 hp from the following mods:
-Buschur 3" turbo back exhaust
-APEXi S-AFC
-Aerospeed air filter

I have been told that the following would be good BOVs:
-APEXi dual stage
-Greddy Type S
-HKS SSQ
-Turbo Smart Dual Port
and recently from looking on this site
-Forge recirculating BOV

I also want a louder BOV than the stock one.
Now based on my driving habits (not alot of consistent high boost, daily driver, but I want it to be able to handle high boost if necessary) which BOV would be best for my ride?

Apparently, alot of threads are saying that Forged is the best and Greddy kinda sux. My guy that has tuned my EVO for me said he personally liked the APEXi. I don't know what to do!!

 

I reccomend the Blitz BOV with the harder spring.

This piece has a filter to KEEP Bov clean and a horn to make it louder if NEEDED.

you'll scare them all off if ya get a turbo xs rfl .that shat is loud

 

I would stay away from the Forge DV BOV.

 

Never had a problem with the Forge. Been working perfect since I've bought it which was like 6 months ago.

 

Greddy Type-s here, no problems at all. It’s definitely louder than stock and you don’t get that compressor surge when you left off the gas quickly like you do with the stock BOV.

Granted I am not making as much power as you, but the Greddy looks like a solid product to me.

 

stock unless you like to deal with your car running a little out of whack.

Also I went through 3 valves before throwing in the towel and saying stock will never leave my car. (also my stock valve as 0 leaking issues) I tried the HKS SSQV valve which i personally hated, driveability was horrible. I tried the Forge recirc valve, which i thought was ok, but compressor surge was a problem i couldn't get rid of. I also tried the Blitz DD valve, which was the best of the 3 by far and I was venting it to atmosphere. The only complaints I had with the blitz was it would cause the car to judder occaisionally at low rpm's while in gear.

I have head the greddy valve does well on these cars.

Stock or a 1G BOV. I currently use a 1g BOV off an old Eagle talon. I did a pressure test and it held up to 25psi. Unless you plan on running a ton O boost, The stock or a 1g will work great.

 

Get the greddy and remove the small spring. drivability is like stock, but it holds more psi and it also has a great sound.

 

oh by the way, i've had the greddy, forge, stock (obviously), and a 1G all on my car at one point or another.

Greddy is the best so far (with the small spring out)

 

Do you have the Greddy recirculating or vent to atmosphere?

 

maybe its just me but I highly doubt your making 325 with a exhaust standalone and a filter

 

I say get a Tial.

 

the stock bov on the E8 MR is made of metal now. looks like a real solid piece. I could order one from the dealer but it might be expensive.

 

Is a Tial recirculating or vent to atmosphere? Or can you set it both ways? I really want to get one that can be set either way.
