Tial 50mm BOV Question

[bigjacsoc]

If I get a Tial 50mm BOV and I wanna run low boost like 7-11psi but then wanna turn the boost up to 15psi every once in a while would I need to get new springs or can I just get a 7psi spring and be able to run anywhere from 7psi-15psi?

you need the 11 psi spring

if you go on Tial's site, they give you a chart for selecting the correct spring for your engine, not your boost.

generally sr's run 18-21in/Hg (vaccum) so Tial recommends their 11psi spring.

Idk if it makes a difference but I have an S14 Kouki SR with T28. What's the vacuum on it or can you direct me to a site with it?

my buddy's S14 SR runs about -19in/HG

so it would still be the same spring

the only way it could really go up is if u have big cams

also the springs are inter-changeable

Thanks, I know they are interchangeable but was just wondering how annoying it would be to have a Tial. I actually don't have it in yet I am just looking for an S13 hotpipe for my SMIC setup and if I can't get one used and have to get a new hotpipe and BOV I want it to be a Tial.
