Specs At A Glance

Good To Know

Q: Can I change the boost pressure later? A: Yes, the spring can be swapped for a different pressure rating, and a boost controller can also be added to adjust the opening point.

Q: Does this bolt directly to a TIAL manifold flange? A: It is built for TIAL MV-R style V-band flanges, but always confirm the flange diameter and bolt pattern on your manifold before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
