Default Tial-Q BOV

So I finally found my lost Tial-Q 50mm blow off valve (BOV) looking for something in the garage this weekend. This is the BOV I had on the turbo car before my big part out last year. I bought it new; it has low miles and was well cared for, so it is in excellent condition. It has a 2.5" stainless TIG welded tee fitting so it can be installed right into the charge piping. No welding required. The tee is tapped for a GM IAT sensor (shown but not included). Includes the vacuum hose barb fitting, the v-band clamp, and the aluminum weld-on fitting that came with the BOV. THIS IS A REAL TIAL-Q, NOT A CHINESE KNOCKOFF.

For those who do not know, the Tial-Q BOVs look great but more importantly they work really, really well. They will hold lots of boost, and release it very quickly when you close the throttle. Assuming you use a good vacuum source and line, the Tial-Q opens fast and hard, and makes more of a crack sound than a ppfffffsssssssssssssssssssstt sound. Excellent quality. This is the newer generation valve, not the older standard Tial BOV.

More info

$210 OBO with the tee fitting (GM IAT not included). They sell for $260 shipped new, without the tee fitting. No lowballs, this is practically a new BOV.
