Trying to get my Type R dialed in for my FD....currently, I am getting some compressor surge, so I assumed to soften it up some. I went ahead and took the valve off and went to adjust it softer, and it is almost as soft as it can get.....I mean like 1-2 rotations away from having no pressure. So my question is what can I do about this, or what could be causing this?



The top nipple is where I have my pressure source line running and the bottom nipple is open to atmosphere. Now I am running a 60-1 at around 12psi....I was using an Apex'i Twin Chamber, worked great, no problems....now with the Type R, it is just not reacting properly. Is it just too much BOV for a 12psi single? I have a TIAL sitting in my garage, but have to get around to haivng the flanges adapted and wekded on to make it work, which I will do if I have to....but I was jus curious about trying to get the one I have on the car to work properly.



Any help would be appreciated.

some of the type r bovs need both vacum sorces hooked up the type r heavy duty .i run a type r standard on my car and have had zero problems. checkto make sure there is no other problems with the car. i am running 10 pis in my car , have the bov adjusted tight . not loose like you are trying to do.

I had an Apex'i Twin Chamber and M2 Large before and it worked fine.....then switched to a Greddy FMIC and Type R....and I just can't get it dialed in properly.



I thought about trying it at around half in to see how it would react, but I didn't want to adversely effect my car any more....would tightening it up some help it open faster?

It also may depend on what spring you have in it. I know greddy makes a pretty stiff spring for it. Not sure what the spring rate is right off though.

i had the same problem and the only way i got rid of the compressor surge is having the adjustment screw all the way up....ill try the vac source on both nipples

i've been using the same type R bov for a while now. just have to adjust it drive it adjust it a little drive it....mine gets a little compressor surge which is fine...

I had no problems when i had the twins on. Now i got a 62-1 and i get a little bit of surge below 3500rpm, but no problems above that. Havent softened it up either. I have had to replace the o ring twice so far.

Which spring do you have in it???

The GReddy Type-R BOV comes standard with the "stiff" spring.



You need to order the softer "std." spring and swap them out.



The stiff spring doesn't budge under 20psi!!!



BTW, using the bottom / angled fitting doesn't do jack **** to it's operation, unless you're running closed-loop.

That fitting just "leaks" into the BOV outlet.

Blow into it and you can hear it venting into the BOV outlet.

yea the type-r's "stock" configuration is for highboost situations.

hmmm it doesnt budge below 20psi... i dont plan on being over 20psi too often
