Water/Methanol Injection Kit for Forced Induction Gasoline Engines

Water/methanol injection for forced induction (turbocharged or supercharged) gas-powered race engines is a proven means for effectively reducing engine inlet air temperatures and suppressing harmful detonation. This allows racers to reliably increase boost and advance ignition timing—without using high-octane racing fuel—for power gains of up to 20%. AEM’s Water/Methanol Injection Systems utilize the most robust hardware combined with more advanced features than any other comparably priced water/methanol system.

Our breakthrough injector design uses unique Swirl Generator Technology that improves atomization to deliver faster inlet temp cooling and uses less fluid to maintain inlet air cooling. We include three Swirl Generators that deliver 250cc, 500cc, and 1000cc of flow. In testing at AEM, the new V3 250cc WMI nozzle and the V2 250cc WMI nozzle both achieved a 90-degree inlet temp reduction; however, the V3 nozzle design achieved this reduction nearly 6.5 seconds faster. Consider that on an average sportsman drag car this can represent close to 40% of track time. On a road race car, applying more timing 6.5 seconds faster can mean a critical time to pass on a corner exit.

We then tested a V3 250cc injector against a V2 500cc injector to see if the larger V2 injector would improve cooling speed. The V2 500cc injector achieved nearly identical cooling speed as the V3 250cc injector, but it required almost 44% more fluid to achieve the same cooling. Less fluid used means fewer refills of your WMI tank and less money spent refilling it. Using the V2 500cc nozzle with a one-gallon tank, you will get close to 7 minutes and 50 seconds of run time at full pressure. Using the V3 250cc nozzle with a one-gallon tank, you will get 13 minutes and 30 seconds of run time at full pressure.

This kit is boost dependent for forced induction vehicles up to 35 PSI of boost. The Boost Dependent controller has an on-board manifold absolute pressure (MAP) sensor with a molded-in nipple for a boost hose pickup.

NOTE: Note: FOR OPTIMUM RESULTS, ALL WATER/METHANOL INJECTION SYSTEMS AND GAUGES SHOULD BE RUN WITH AN AEM INLINE FILTER (AEM PART #30-3003)

Features

  • Boost Dependent and Multi-Input (0-5v/frequency) progressive controller designs feature large adjustment knobs, integrated plug for harness connection, integrated fuse, covered status light and test button for enhanced splash resistance and mounting tabs
  • Wiring harness is terminated with a positive-lock connector on one end with color-coded wires to ease installation, integrated pump ground circuit and additional wire for optional on/off fluid solenoid
  • “Boost Safe” failsafe output included (for complete failsafe under all conditions, see our Water/Methanol Failsafe Device)
  • Heavy-duty high-pressure injection pump features integral fittings, a Santoprene diaphragm and EPDM seals to resist corrosion. Our pump maximizes line pressure for optimum atomization and its quiet, smooth operation is almost undetectable
  • Precision-machined billet-aluminum injector with integral check valve
  • Three interchangeable injector nozzles to cover a wide variety of HP levels (250cc/min, 500 cc/min & 1,000cc/min)
  • 1.15 gallon tank with anti-starvation reservoir, integral conductive low-fluid sensor and positive lock connector (tank-less systems available)
  • 20 feet of injection tubing included
  • LED dash light for system status and low fluid warning

Not real good quality

I have learned through tuners and enthusiasts that this kit has issues. The nozzle fails consistently after a few months. So I went a different route and found that another brand is far superior.

Not too bad, could be a lot better

Very happy with MAPerformance,
I received the kit very fast, I'm disappointed with the mounting points on the controller it's not designed to be mounted in any easy way, it should come with 2 threaded holes to attach it, I'm also disappointed that you pay almost 500 dollars for a kit, then have to buy an additional filter and meth solenoid another 80 bucks. When I received the kit I took a peak inside the box to see that the controller was separated, the backing was not attached to the controller and the supplied screw would not thread into the back, had to buy a rubber nutsert to thread the screw into the back. The wires are great, nice and long easy to hook up. Enough nylon line to run about anywhere you need. I would recommend this kit to anyone. Haven't actually ran the kit yet in the process of a trans swap but when I do I'll update

Fast Service

Third such kit I purchase all from MAP. Always great service. Product does increase power.

Thanks
