My car pulls 18 in/hg vacuum and tial offers a 16 in/hg and a 20 in/hg. Im smack dab in the middle. Im thinking maybe choose the 20 in/hg spring for a slightly slower response and possibly keep some boost (minimal if any) in between shifts without causing compressor surge? What do you guys think of my theory? lol. thanks for any advice.

Hmm would think if you got 20 it won't close at idle. This wouldn't be good. So would think 16 is best. I have tial on my 97 talon but forget what spring i went with. I would contact tial and ask them directly.They seemed very helpful have talked to them several times mostly about gate questions.

ugh, the 9psi spring pulls 18in/hg at idle. It's the white one. http://www.tialmedia.com/documents/w3_tial_bov50_sp.pdf

the place i am ordering it from somehow doesnt have or list the white spring... Just goes from 16 to 20, which is stupid.

thanks, i will order the 16 for now and see how it works. Like i said in the last post, the place i am ordering the BOV from only lists the 16 and 20 spring. Only reason why i am going to still order through them is because i get 30% off.

the -9psi spring is for the BV50, not the Q.

if you don't like the way the -8psi reacts let me know and you can swap for the -10. technically your vacuum is rated for the -10, the bov uses the vacuum spike you get when you chop the throttle so your -18in/hg will probably spike well over -20in/hg

forgot to mention, i ordered the new Q 50mm BOV, not the OG 50.

Several years later... Finally made some boost last night and have compressor surge. Gonna need a lighter spring for sure.
