Can someone explain the spring issue, and why it includes so many types of springs? And whats the best choice for the 951? Meaning the most power efficent one.

I also have a Tial 46mm and would like to know. Mine didn't come with extras since it was on the car when I bought it. What are my options?

I've heard that a good rule of thumb is to use a spring that holds about 80% of the desired boost.

I heard the .8 and .9 springs were good for our car, but I was wondering what other type of springs can be used to hold more boost.

If you give them a call, they can fax you a sheet. It tells you the colors of the springs and how much boost they hold.
WG46mm has 2 springs. Large and small. You can mix and match to get what your looking for.
small spring - bar - psi - spring od is 1.875in
sm.yellow - .2 - 2.90
sm.red - .3 - 4.35
sm.green - .4 - 5.80
sm.blue - .5 - 7.25
big springs
big yellow - .6 - 8.70 - spring od is 2.36in
big red - .7 - 10.15
big green - .8 - 11.60
big blue - .9 - 13.05

Then they tell you to mix big and small springs to produce 1bar 1.1,1.2,1.3and 1.4bar(20.30psi) set ups

I run a 1.1 bar set up, Works good
