- Vortech Maxflow Race Blow-Off Valve
Get that signature sound between shifts with this Vortech Maxflow Race Blow-off Valve. Features include a 360 Degree discharge, all Billet aluminum construction, and large "rolling diaphragm" configuration with dual vent porting allowing for a quicker valve response. These units can easily be retrofitted to standard Greddy/HKS style mounting pads. They are adaptable to all types of boosted engine installations and can be mounted in any position. Race BOV with standard spring is preset to open at 5 inches of vacuum, Race BOV with high tension spring is preset to open at 17 inches of vacuum. The mounting flange configuration is the same as the current Vortech Race Bypass and they are a direct replacement on VTA (vent-to-atmosphere) applications.
