Variable water-methanol injection kit with boost-proportional control for turbodiesel engines. The 12× SEMA Award-winning Stage 2 TD progressively varies injection flow in proportion to boost pressure. Perfect for tuned diesels that need EGT management and additional cooling under load.

What's in the Box

• 300 PSI EPDM high-pressure pump (100% methanol-resistant, double-sealed)
• VC-30 variable controller — progressively adjusts injection to boost pressure
• Hyper-Sonic™ injection nozzle(s) — sized to your engine's power level, with integrated 100-micron filter
• 3-litre reservoir (black) with pump mount
• Fluid level switch with LED warning light (red)
• All fittings, pressure lines, and mounting hardware
• Comprehensive installation manual with dyno test reports

Key Features

• Injection type: Variable, boost-proportional (VC-30 controller)
• Control: Set your start and full-injection boost points — controller creates a linear injection curve between them
• Response time: 1.5 milliseconds
• Engine compatibility: All turbodiesel engines up to ~2.1 bar boost (TDI, HDi, CDI, dCi)
• EGT reduction: Up to 120°C lower exhaust gas temperatures
• Power gains: 10–25% more power and torque with cleaner combustion

How It Differs from Other Stages

Stage 2 TD adds variable injection over Stage 1 TD's fixed on/off. For an OLED display with Dual Stage Technology support, step up to Stage 2.5 TD Power-Max. For 2D mapped injection with EGT probe and fuel economy optimisation, go Stage 3 TD MPG-MAX.
