Synchronic BOV
warning...Not quite. They're not forced to spin backwards, it has to do with pressure waves coming back off the closed throttle plate and striking the compressor blades. Some of that pressurized air also passed back through the compressor and out the inlet of the turbo. This combination is what causes the dreaded "surge" noise. Sure, the compressor wheel slows down, but it won't reverse.
Or, think about it another way. You have the shaft with the turbine and compressor wheels spinning at almost 1667 revolutions per second (assuming 100k rpm which isn't a bad assumption at full bore, some turbos spin over 200k rpm). That's a whole mess of inertia to overcome to make it spin backwards in a fraction of a second. Which means a very large force is needed. I have a feeling if you do the math, you'll likely snap the shaft or totally destroy the blades before that happens. Not only that, but you still have exhaust passing through the turbine wheel, causing "forward" motion.
Also, ryan, you provide no links. The lazy among us won't search for it if you're going to shill it.

if you can take the time to type all of that im sure typing synapse bov in google isnt too hard
yea i was gonna get a tial but ss recommended getting the hks at the time because he said tial leaks under vacuum
they also have amazing wastegates
While I'm being pedantic, his original post isn't quite clear what BOV-related problem this particular model solves. He appears to imply it corrects the "running rich during shifts" problem, which it will not.

Of course it's not hard to search. However, my point was that if he was going to pimp it to us, and offer a possible group buy, that he could post up a link.
