i got a tial bov with a 7 psi spring, but will it release pressure if im only running 5-10 psi??? the spring is really tight and hard to push in. would appreciate any feedback

yes it will work, but for a honda, you bought the Tial with the wrong vaccuum spring

i have a 7psi, what do i need a 9psi or 11psi??
do u run a tial bov in your car??

Tial doesn't rate the spring pressure on the blow-off valve to what psi you run, rather to what vacuum you pull at idle.

Engine Vacuum Reading Use Spring
-22 and -23 in/Hg -12 Psi (-24 in/Hg )
-18 and -21 in/Hg -11 Psi (-22 in/Hg )
-14 and -17 in/Hg -9 Psi (-18 in/Hg )
-10 and -13 in/Hg -7 Psi (-14 in/Hg )

Look at your boost gauge at idle (assuming it reads in/hg)...use the chart I listed above and make the purchase.

great ill check it out and see which spring ill need, thanx

on my knockoff tial, i had to cut about 3 coils off the included spring to get it to function correctly.

Wideopentuning

The Tial needs to have a vacuum line from a large vacuum port and the line needs to be high quality and not colapse. I ran one on my turbo Miata and even at 3.5 psi it would blow off clean and crisp......once I installed larger vacuum ports into the intake manny.

for tial bov yes it will work

dizzyek

mine goes off crisp and clean from 6 psi up

also goes off in vacuum right before boost

Note sure what spring it came with though.
