Craving Boost blow-off valves are CNC machined to critical tolerances, less than one thousandth of an inch, to ensure that every one operates perfectly.

Machined from bars of solid billet 6061-T6 aluminum, anodized to achieve a hard durable surface, our BOV's are designed to take a beating and keep looking beautiful. 

Made with the utmost pride right here in Canada, you can be certain that our products meet the highest standards.  The piston is hollowed out for light weight while still retaining strength where it counts, this is the only part that moves so having it light and nimble is a good thing. 

Also it is constantly being abused by the spring and smashing against the seat, so it has to be strong.  The piston is turned on a CNC lathe to 1.97" in diameter (50.038mm), making it one of the biggest blow off valves on the market!  The overall diameter of the blow off valve is 3", giving it a very strong presence in any engine bay. 

One extremely unique aspect to our blow off valves is that we've taken a very elegant approach to their design.  Other blow off valves are machined with sharp and blocky corners while some are cast and downright ugly.  Ours are curvy with smooth edges all over, making them very appealing to the eye.

Our design prevents leaking with our specific combination of seals, so the piston will seal harder with more boost pressure.  Some BOV's will leak or tear at higher boost, not this one!  The Forcefed Blowoff Valve has been pressure tested to 120psi without leaking. 

One of our favorite parts about the valve is the way it mounts to the intercooler pipe.  Just like any other BOV a tube gets welded to the intercooler pipe, but instead of big and bulky t-bolt clamps or weird set screws that stick out all over and look ugly, our BOV's mount very smoothly with 4 button head screws.

The blowoff valve mates to the welded tube with a sleek visual line, continuing those nice curves right until the weld.  Use a beautiful TIG weld on nice aluminum or stainless steel intercooler piping to complete the visual package.
