Hey guys, thought i'd make a useful contribution as first post, i have a 98 blacktop SR in a 91 FB. I have always wondered whether the knockoff blow off valves were worth a damn, so i thought i'd see for myself. Just recently purchased the 'pull-type' hks ssqv knock-off blow off valve, $65.00 shipped off ebay. I disassembled it and compared to a friends real ssqv, and then put it to use, here's my review:

Quality:
Gaskets on knockoff appear to be same rubber, thickness, and elasticity, however different color. The knockoff has a cheaper spring i've noticed, and the adjustment screw isn't attached to the inner diaphragm press in the rear of the bov like the HKS.
Performance:
The bov came with block off plate, o-ring, c-clip, two t-fittings, hose clamp, and steel flange <- i was really pleased. Welded the flange on my custom hotpipe and mounted the bov w/o adjusting the screw.
The bov sounds exactly like the hks ssqv, and i did a simple bag test under throttle over the bov, it did not appear to leak, and the bov did not stick open either when the throttle was released.
My opinion:
Definitely worth the money, it is nearly an exact replica of the hks ssqv and does not leak. It sounds great and i was happy with everything that came with it.
If you're cheap or broke, this is a good bov for the money, and definitly not a piece of crap knock off as compared to other types of bovs with cheaper diaphragms.
Heres the ebay link:
