Would be real curious to see the difference in spool up

I have a cast t3 manifold in my shop... but the flapper dosent clear the casted flange port. Perhaps "porting" the area for clearance would work(???). Or would to much material need to be removed?

Woah!!! Pretty interesting consept. You could even use a Pneumatic Valve/Solenoid to control the QSV and ECMLink BCS Control to drive it.

In that case it's probably the wire and the welder. Also better wire does help a bit.
I have tried cheap welders and it was night and day difference, sure technique helps but it won't make your welder any better.

I use the flappy sanding disk to make it all smooth, but Stephen is right gas is the way. It's on my list

It should provide a quicker spool yes. Unless Jay, were you thinking about setting it so one side is either closed or open, manually controlled so you can set it before the race depending on what kind of race you are doing?

I guess if you are using a waste gate to open it there will technically be a gradual open...
I guess you will have to find the sweet spot. Not if he is using a ebc to open, will it not just abruptly open as soon as it hits the ebcs designated boost?

Very interesting. The slope on the RPM line is massively steeper with the enhanced spool, and the increased airflow is also quite substantial. Did you end up using the EBC to open it at a certain boost pressure?

Someone already made one like you describe. http://www.supraforums.com/forum/showthread.php?742098-Kevin-s-Divided-Manifold-Quick-Spool-ValveI love the diesel valve I linked, it's a brilliant piece of engineering and quite nice to look at, but that cost...ugh. The trick to using twin scroll with a spool valve is to run a big turbine housing to offset the lack of flow; you will be in "net positive" territory if you match it properly. Also, Borg-Warner is using spool valves on twin scroll EFRs starting early next year, so they see something in it too.
