so if im planning on running 12lbs of boost, would i order the tial blow off valve with a 11lbs spring?

someone shed some light on the subject

difference in springs and why there are different pressures?

 

The spring that is used is determined by the amount of vacumm your motor is pulling. Download this pdf from tial. Find out the average amount of vacumm your motor pulls for your motor at idle. Then get the color spring that the chart tells you to run. You can open your BOV or look on the box to determine what color spring you currently have.

The amount of BOOST running is determined by your WASTEGATE spring.

 

lol, totally not even the question i was asking but its cool

andy knew what i was trying to ask though, but honestly who does all that.. is there maybe a way i can call a company and tell them what my set up is exactly and they can recommend something that will be close if not exactly what i need.... and how serious is the spring rate of the blow off valve if someone gets it wrong.... what can it harm and how bad etc

thanks!

 

ok i talk to a buddy of mine and i think i have a better understanding of it, ill just pick up a 7lbs one most likely and go from there, thanks guys
