It's HAMMER TIME. Here's one SERIOUS kit that atomizes water/methanol fluid into the finest droplets possible. At double conventional pressure it has no equal within the industry. Intake Air Temperatures WILL DROP HARD.
A Street Tank and HAMMER WMI Pump are combined together in the trunk. Tank Level Switch plus clear site glass keep the driver informed about basic status. The 400psi pressure gauge is vital for initial tuning and ongoing health monitoring.
Most all pressure-side plumbing is done with 4AN + 6AN for modular convenience and optimum security. Supporting a 1400hp Audi RS3 requires more than brute force, though. A Big Amp Pump Driver is installed between ECU and pump because current draw is massive. Yet fine PWM control over flow rates is remarkably linear and predictable making tuning remarkably easy.
A pair of air cooling nozzles is activated in sequence as manifold pressure rises. Initial flow rate is 5gph and is started at very low boost. Gravity and vacuum siphoning are blocked by our Check Valve that's cleanly integrated within the first nozzle holder.
Later, the second air cooling nozzle sends a bigger 8gph. It goes to work when the ECU commands its flow control solenoid to open. Staged operation permits huge combined flow rates without suffering the wall wetting and poor atomization otherwise common at lower engine loads.
Yet another major element is a FLOWsafe Inlet Sensor array. It threads directly to the tank (at its bottom under the pump). Fluid is drawn through a giant 1/2" port and then split into dual 6AN hose paths to serve the HAMMER's two oversized inlets. This positioning minimizes pressure-related spikes/dips and makes flow trend data easy to read vs a chore to decipher.
In this case, the spray fluid will be non-volatile 50/50 mixture. So, the main feed from pump to the front of car is done with 1/4 Nylon tubing (for lightness/ compact fit). Yet, once in the engine bay, plumbing still reverts to black braided 4AN hose. -for full GLORY.
