I've lurked on this site awhile looking at the great fabrication and welding.
The divided spool valve has been discussed over at theturboforums for quite awhile and is something I am interested in.
I seen a thread here about the same topic, and thought I would share some info.
I really don't give too ***** about that seller or if you think he is a scammer. I was pointing out that someone has already made a copy for much cheaper. Whether you actually will get what you pay for, I have no idea.

A copy of a picture is always easy to make.

Quite unlikely, your choice of wording reveals you for a fraud. Go away.

do you all think this would work on a reg t4?

Don't know why they wouldn't. I think the ones Sound Performance has shown dyno graphs for, are T4's.

my t 4 is not divided so i would think using this was make a block = less flow?? but maybe i dont understand how it works??

Bossman

Yeah, bad idea. You need a common collector and a divided turbine housing. No way around it.

mycarslow

yeah i was looking for a way to spool my turbo faster on my d16

You can only take advantage of this flapper valve if you have a divided housing turbo and a non-divided manifold. I have no idea if running this would cause positive or negative results on a normal housing turbo. It will create more exhaust pressure flowing out of the manifold, but then it will slow down the flow to compress the exhaust gas.
