so im getting a fp black installed on my evo 8.
i was wondering if i would need a tial BOV or something similar to hold up my 30psi boost.
and if so, is this all that i need?

do i need any special brackets for fitment?
do i even need a BOV?
are there any other bov that you would recommend?

thanks!

Tial BOV seems to be the popular choice among the evos on here, however, its not the only choice, there are a number of other good tested bov's such as synapse, stock 9 or jdm metal bov (crushed)...etc
From what I have read, evo 8's come equipped with plastic bov's that tend to leak even at stock boost lvls so if ur planning on running 30psi then its probably a good idea to swap it.

You will need an aftermarket ucip that is flanged for a tial bov.
do i even need a BOV?
If ur stock one doesnt leak at higher boost then u dont need it, however, seeing all the data on the stock 8's, they all tend to leak.
are there any other bov that you would recommend?
synapse, forge, aps twin vent....etc
if u'r running on stock maf (non sd) then I would recommend a recirculating bov. Tial also makes a recirculating bov.

here is a list of some of the bov's out there:
