Hybrid Dual Outlet Valve by Go Fast Bits

Known as the “Hybrid”, this world-first became the flagship model of the newly formed company Go Fast Bits. The two venting ports of this revolutionary valve were staged on the body such that the recirc port opened before the atmo port, helping to prevent backfiring and stalling on cars with a MAF sensor, whilst still giving the signature blow off sound when the car is driven harder.

This innovation was so successful that the technology has since been adopted by almost every other BOV brand on the market. The Hybrid then went on to evolve into GFB’s next world-first, the venting bias adjustable BOV now known as the Respons TMS, and then to the electronically adjustable version, the Deceptor Pro.

With the spotlight focused on these current products, the Hybrid has been absent from the market for some time, but in celebration of the 20 years since the invention of one of the most influential BOVs the turbo world has seen, GFB is bringing the Hybrid back!

With the same staged venting outlets as the original, but now with the ability to configure for full recirc, full atmosphere, or 50/50 venting, and a huge range of direct bolt-on kits for popular vehicles, the new Hybrid offers all the benefits of dual port venting, at an affordable price. Grab a piece of history for your car now!

Great Hybrid BOV

Quality is on point! Sounds great! I love the hybrid functionality and the ability to adjust the spring with the turn of an external allen bolt. No swapping springs or installing/ removing washers. Definitely worth it!

GFB hybrid

Fast shipping, simple install, spring load was set almost perfect out of the box on a WRX running 20psi

Awesome Hybrid BPV

Makes a lot of great noise, and I've seen no increases in feedback knock after installing even at 100% vent
