Tial spring
Tried to do a search on this subject but all i got was completely irrelevent to what I was typing in the search box
...so here it go's ..Just bought a Tial Q...but I wasnt offered ..the choice of spring...(read that most people get the 11psi spring)..I think thats too big for my application..since I'm only going to be pushing around 270-300whp (stock block)..which I suspect won't be much at much psi..because of the size of the turbo I'm going to be running (picked a bigger turbo because I wanted some room to grown. building block soon)..so with that being said..should I just get the 6psi spring..while I'm running low boost..so the BOV will release air sooner?..I read that too soft of a spring..and the car will have trouble idling...deployed right now..due to get back real SOON..and I can't really check where my engine vaccum reading is at...wanna order the correct spring just incase(new turbo don't want compressor surge
)..thank guy's

Re: Tial spring
the bov spring has nothing to do with how much horsepower or how many lbs of boost
it has to do with the engine vacuum at idle, if it were me i would get a 9lb spring since the 11lb I have only had bad luck with surge on the 4 tial bov's ive had

Re: Tial spring
Thank you..I was well aware that the you chose your spring..based on the your engine vacuum at idle..but...I also thought that if the BOV had a 6psi spring..it would "blow off"...at 6psi+ only...so if you build up anything under that..the BOV wouldn't release pressure...so i figured a 11psi spring wouldn't do me any good..since I'm probably gonna run a lower boost pressure then that..and the BOV wouldn't open...I'm sorry upon googling..that's what other individual's made it seem like..guess I'll just try my luck with a 9psi spring ..anybody else wanna chime in?

Re: Tial spring
it has nothing to do with the amount of boost, the vacuum reference is correlated to the spring so that when you lift off the gas and the engine goes to vacuum , the spring will be soft enough for that vacuum to be able to open the valve
when your in boost the vacuum signal becomes a boost pressure to help hold the valve down
