ARM Motorsports TiAL Q 50mm BOV

The ARM Motorsports TiAL Q 50mm BOV is a blow-off valve built around the TiAL Q, the first revision of the original TiAL BOV, with a large 1.98 in (50.5mm) valve. ARM says it bolts up to any standard TiAL flange without re-welding, and this version has a 10psi spring that the brand describes as suited to the N54 and paired with its TiAL Flange Charge Pipe. The body and all internals are CNC-machined from 6061 aluminium alloy, with a V-band aluminium mounting clamp, a Viton O-ring valve seal and a high temperature silicone Nomex-reinforced diaphragm. The brand claims the valve flows 60% more than the original design and that a single Q can support up to 1,800hp.
