Our Rapid Acting Control Elements (aka "RACE valves") are now the fastest/most accurate flow control actuators on the market. They function at 220psi. Whereas, the previous best accept 180psi and yet others struggle at just 150! Featuring full stainless steel internals, RACE valves are impervious to pure water, pure methanol, or any blend. Achieve EFI-level control precision and enjoy it for the life of the car. -no rebuilds are ever necessary.
These ultra-fast 4AN threaded solenoids are compatible with all Snow controllers. They work even better with advanced options like Cortex EBC, FrostByte, and Torqbyte. Standalone ECUs do the job with even more flexibility and sophistication. (AEM are specifically not compatible.)
Subarus are interesting cars that demand similarly unique water/methanol configurations. Between the top mount intercooler (TMIC) and the throttle body there is essentially zero stand off distance. So, mass air cooling is done from the side of the compressor housing (known as the "volute" position). With broad torque bands that start early in the rev range, these turbos need help up top. With a BigUPPER kit, we spray directly at the center nut to safely improve air flow at high RPMs.
This specific package delivers world-class OCTANE via direct port nozzles (45cc). It upgrades a vehicle already setup with USRT's BigUPPER pre-compressor system (90cc) and also a TRUTH Base Kit with main air cooling nozzle (225cc) placed in the turbo's volute. (Yes, of course, we can help builders equipped with simpler systems or none at all.)
Pre-compressor function is controlled more simply by a standard Flow Control Solenoid actuated by our Boost Trigga (Hobbs switch). Spray starts as the turbo approaches max boost and not before.
Just before timing pull is expected, direct port octane flow is regulated via a pair of RACE valves. Whereas, air cooling from a volute-mounted nozzle can be done early in the boost range and in proportion to engine load via the third valve seen at bottom right.
