Default Anyone need a spool valve?

I posted my used T4 spool valve in the classifieds, if you've been thinking about getting one.

just like a vent in a car. you close one and the other ones blow more out with the fan blowing the same speed. best way i can simplify it.

you need a divided housing turbo for it to work. Basically, one side of the housing is covered and it will slowly open when your boost rises. This will allow for a quick spool for a large rear mount turbo...

There's other links and video on how they work. It uses a valve to block part of your turbine housing increasing velocity of the exhaust to spool the turbine, at a preset level of boost it starts opening allowing full flow of the exhaust and less back pressure.
