Direct port distributes spray evenly. However, putting mist at the backs of those intake valves ON TIME and with PRECISION can only be done with ultra-high precision fast solenoids. Our RACE valves look a lot like fuel injectors because they're engineered to function much like them. -at five times the pressure.

Advanced builds demand Rapid Acting Control Elements, the next advancement for WMI tuning and auxiliary fuelling. -bridging the functional gap with EFI!

For fine tuning, a modern WMI controller is critical. Go with elite equipment like the TorqByte or FrostByte. The basic DEvilsown controllers (but not AEM) are compatible but very limited in function. Of course, full-spec ECUs with closed loop feedback will do the best management job. -endless possibilities for fuelling and defeating the knock monster!

RACE valves are corrosion-resistant and deliver EFI control precision at 220psi. -amazing! Maximum recommended flow at such pressure is 500cc/minute.

With this upgrade you get all the fittings needed to upgrade your kit to the benefits of RACE direct injection. This includes one race valve per 2 cylinders, Tee fittings, straight or 90 nozzle holders, and a small portion of tubing to hook it all up.
