So this maybe a dumb question, but will a tial qr bov that was on an evo 10 work on an evo 8? i see that the ones for subies are a little different, and i assume that is just the resurculating part? not sure though and advise would be appreciated.

 

they all work the same when it comes to tial. the outer cover is made different if it has to recirculate, but even that one you can leave open and it will work the same as the thats only meant to vent to atmosphere. if your trying to keep it oem then you want the recirculation one. same system for subarus as non speed density evos

 

Yes it will work only difference is stated one is vent to atmosphere, and one is recirculating

 

ok thanks guys is there a benefit to venting to the atmosphere, vs recirculating

 

It's not so much the vta, it's speed density vs mass air.

 

I like VTA because its less piping to deal with and looks better. You can run VTA on MAF or SD as long as its tuned well. I ran VTA for a year on MAF before going SD.

 

all you helped a ton thanks alot! i learn alittle more every day from this forum

 

yes it will work

 

just make sure to get a real Tial

 

are there alot of nock offs that look like the real ones?

 

Yeah but the real ones have "Tial" and "Made in USA" stamped on them. Fake are just plain with no writing on them.

 

good to know
