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 Injection Kits utilize robust hardware and deliver more advanced features than any other comparably priced water/methanol injection system.

Water/Methanol for All Boost Levels of Forced Induction Gas Race Engines
AEM offers two different water/methanol controller designs for gas vehicles:

One is boost dependent for forced induction vehicles up to 35 PSI of boost (kit PN 30-3300). The Boost Dependent controller has an on-board manifold absolute pressure (MAP) sensor with a molded-in nipple for a boost hose pickup.

The second controller (Kit PN 30-3350) features a multiple input design that enables users to install AEM’s Water/Methanol Injection Kit on ultra-high boost vehicles (above 35 PSI) using a 0-5v voltage-based external MAP sensor.

Note: FOR OPTIMUM RESULTS, ALL WATER/METHANOL INJECTION SYSTEMS AND FLOW GAUGES SHOULD BE RUN WITH AN WMI INLINE FILTER (PN 30-3003). For additional insurance against unintended flow, particularly when the pump and tank must be installed higher than the injections nozzle, we recommend adding our optional High-Flow Low-Current WMI Solenoid (PN 30-3326).

Robust, Easy to Use Controller Designs
The new controller designs (Boost Dependent Kit PN 30-3300 & Multi Input Kit PN 30-3350) feature large, turn-resistant knobs and larger numbering to easily set accurate start and full activation points, with covered status LED and test buttons for added splash resistance. A plug is integrated into the controller housing for mating to the redesigned wiring harness’s positive-lock connector. The Boost Dependent controller housing has a molded-in, barbed nipple to accept a boost hose and a wiring legend on the back. Both controller housings feature an easy to access integrated fuse and molded mounting tabs.

Innovative Injector Design Delivers Faster Cooling with Less Fluid Used
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. The AEM V3 WMI injector is included in every AEM Water/Methanol injection kit and is a direct replacement/upgrade for the V2 injector in older systems (V3 Injector PN 30-3315).

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. 


Heavy-Duty Waterproof High Pressure Injection Pump - Safe for Engine Bay/Frame Rail Mounting
AEM’s internally-bypassed water/methanol injection pump is waterproof and safe for mounting in loactions that are exposed the elements. It does not cycle on and off and provides quiet, smooth operation. It features robust construction including integral hose fittings, EPDM seals and a Santoprene diaphragm that provides consistent and reliable fluid delivery. 


Low-Profile 1.15 Gallon Tank
AEM’s gas Water/Methanol Injection Systems are available with or without a compact 1.15 gallon tank that features an anti-starvation reservoir. A more accurate, conductive low level fluid sensor is integrated into the tank and features a positive lock connector with color-matched wires to the wiring harness. The sensor eliminates any chance of incorrect readings due to interference from debris. 


Simplified Wiring
AEM’s Water/Methanol Injection kit’s wiring harness is terminated with a positive-lock connector on one end and has color-coded wires to ease installation. Both the power and ground wires for the pump are included in the harness which simplifies the wiring process and eliminates any chance of the pump accidentally activating from a short in the system. An additional wire is included for adding an optional on/off solenoid to stop fluid flow when the system is inactive. 

Integrated Boost Safe Feature
The controllers in AEM’s Water Methanol systems include an integrated “Boost Safe” output feature that monitors the entire injection system and triggers a ground signal via an output if it detects a voltage-related error (short, bad connection, broken wire, overheated pump, high or low voltage signal, etc.), allowing users to define their failsafe strategy from something as simple as flashing a warning light to more advanced strategies like pulling boost or ignition or switching fuel maps on a standalone engine management system. Combined with the integral and highly accurate conductive low-fluid switch in the tank, “Boost Safe” can also put your engine in safe mode before the system runs dry. This exclusive feature is found only on AEM Water/Methanol Injection Systems.

Revised Flow Control Strategy for More Linear Fluid Delivery
AEM’s engineers spent extensive time revamping the controller’s flow control strategy for a more linear flow output delivery. This means that the flow delivery better matches an engine’s need for water/methanol injection, which further optimizes charge air cooling and detonation control.

  • 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

  • 20 feet of injection tubing included
  • LED dash light for system status and low fluid warning

WATER/METHANOL INJECTION ADVANTAGES FOR GAS ENGINES:

Reduces Air Inlet Charge Temps
The term “liquid intercooling” with water/methanol injection refers to a highly atomized mist of water/methanol that is injected into the airstream and begins to evaporate. As it does, this evaporative effect reduces air charge temps by as much as 100 degrees, and delivers a more oxygen-rich air charge.

Reduces Detonation (Knock)
Water absorbs heat, and methanol is a cool burning, anti-knock rated fuel. When combined and introduced into the inlet stream, they can effectively increase your vehicle’s anti-knock index so you can reliably increase boost pressure and advance ignition timing using pump gas.

Reduces Carbon Deposits
Modern vehicles fitted with Exhaust Gas Recirculation (EGR) devices for emissions control promote heavy carbon build up inside the air intake. This carbon build-up can create ‘hot spots’ in the combustion chambers that can cause detonation. Water/methanol injection has a ‘steam cleaning’ effect that reduces this carbon build up, and in some cases can increase fuel economy.

Outstanding book - A MUST READ
This is fantasy romance at its finest, and I couldn’t put it down from the moment I started. Packed with classic romantasy tropes that are done so well, especially my favorite: fated mates! The world-building is both easy to digest and detailed enough to feel immersive. It strikes the perfect balance—not too vague but never overwhelming. The world is divided between several groups of people, and the story revolves around the Alaha, who live on the water, and the Kenta, who reside on land. For centuries, these two factions have maintained a fragile peace, but things take a sharp turn when our FMC, Brynn, threatens that peace right at the beginning of the book. What follows is a thrilling dive into a world of magic, rebellion, and secrets. I will say no more, because you should go into this book relatively blind to get the full experience. Brynn, our FMC, is everything you could want in a lead. She’s smart, confident, and refuses to bow to threats. Then there’s the MMC, Acker. Scrumptious doesn’t even begin to cover it. The chemistry between him and Brynn is electric, and their dynamic had me grinning (and swooning) throughout. This book has all the best romantasy tropes: forced proximity, slowest of slow burns, elemental magic, fated mates (done right), political intrigue, and plot twists you will not see coming! Each trope is executed masterfully, blending seamlessly into the story without feeling overdone. If these are your jam, you’ll absolutely love this book. Even if they are not usually your cup of tea, this book may change your mind. While the pacing is fast and gripping overall, it does have a bit of a lull in the middle. That said, the ending more than made up for it—it left me gasping and desperate for the next book. I think I said aloud, “What the hell just happened?” when I finished the last page. This book grabbed me by the neck and didn’t let go. It’s full of banter, twisty turns, and a delicious tension. Probably one of my favorite fantasy reads this year. I am going to be thinking about this book non-stop until book 2 is released!

Cool world building and great side characters
Format: Kindle
I adored the side characters and found them a lot more compelling than Jovie and Acker, if I’m being honest. I really wanted to like her but I found myself getting frustrated by her lack of, I don’t know, real rage for any of the crap people pull on her. Like ok I get this is romantasy but I have a hard time really believing you’re actually as upset at this guy as you claim to be when two minutes later you’re letting this dude shove his tongue down your throat. Additionally, an early running theme is that Jovie is frustrated that there are a bunch of people deciding things for her but the existence of the whole “matched/bond” thing makes much of her autonomy a moot point. Like at one point I think Acker even points out that them getting into bed together is a “foregone conclusion” and someone else mentions that the other matched pairs that don’t end up together ended up literally destroying each other. No pressure. I was a lot more interested in the characterization of Messer, Beau, and Hallis. I knew I was going to be exasperated consistently by this girl when she let Mr. Murder Hottie treat Messer like a war criminal after he almost got himself spatchcocked for them by a mighty-morphing radical with an attitude problem. If my homie went through the battle blender like that for me after I found out he had been secretly protecting me and keeping me company for weeks/months, I would be doing A LOT MORE than standing around trying to figure out if I actually thought he was my friend while Captain Boy Toy did some light torture on him. Also Acker, my dude, if you can still find it in your heart and your loins to get riled up while your sister is having a breakdown in the room over…I don’t know, seek help I guess. I liked the juxtaposition of Beau’s bravado and her militaristic delivery of information to her brother showing she can turn on a dime when needed. Adding the mental toll her gift takes on her throughout time and how she has self destructive coping mechanisms really gave her some cool depth, and I appreciated the vulnerability it lent her. Hallis was a weird character for me at first but I ended up looking forward to his dialogue a lot. Initially, I didn’t care for the way he seemed to immediately just be a real jerk to Jovie and it didn’t often read as playful to me when I think it sometimes meant to. Regardless, his genuine care for Beau and Acker and how he dropped the act immediately when they really needed him made him pretty endearing and I always appreciate a grump who cares. Honestly everything about this book was an A+ for me aside from the two main characters’ dynamic. When Jovie gets pissed at those bats and obliterates a forest? A+ When she tells Acker that she saw the signs that Messer was getting abused and acknowledged she felt shame and that she couldn’t fault him for being complicit in her mistreatment since she had done the same? A+ When she’s sitting there and coming to terms with the fact that everything she knows has been built on lies as she’s flipping through her sketchbook? A++ The writing and setting is great and the book is good, but someone needs to give Jovie a big stick and tell her it’s okay to be mad and smack people with it even if they’re hot.

Interesting. Confusing ending that's too similar to another book
Ok, I had to process almost a whole 24 hours before I could write this review. And long story short, did I enjoy the book, yes. Does it have a lot of interesting and good parts to it? Also yes. But does it also have some major flaws? Absolutely. Now I'm not gonna break down every single little thing in this book. But here are the basics of what I liked, and what I didn't like. The good? I liked the characters. They intrigued me off the bad. The world building is pretty decent. It's a little confusing in the beginning, but information is slowly doled out, and some questions are answered. I found that there was a lot of little twists and turns that kept the story engaging. The magic system is intriguing. But, there are quite a few things off for me. First off, we have another story that has heavy inspirations from other books. There are a lot of aspects in this story that felt directly pulled from throne of glass. And the big twist at the end? Was almost verbatim the same ending as the book how does it feel. As soon as I read it I was like hold up, I literally just read almost this same thing when I read how does it feel when it released like a year or year and a half ago. Now I know no concepts are really new anymore, and inspiration comes for everywhere. But I feel like most stories it's like, oh this book has these vibes, or if you liked this book you'd like this one that's similar. But this reminds me of powerless in where there are like exact plots and plot points taken from other things. Now is that a bad thing? Not necessarily. I still enjoyed powerless, and I still enjoyed this story. But it does throw me. There are also a few red flags that the MMC Acker gave me that were not the good kind of red flags we love. First, when they are riding thru the city and people throw stuff at the FMC and he does nothing? Red flag. When they meet his dad and they demand she vows not only to the king but to the MMC? Red flag. All the secrets he keeps? Red flag. When he SLAPS HER IN THE END? Red flag. I'm not sure how I really feel about him. In the end. This was still an enjoyable read. I did like it and I am curious about the next book. But I am wary about some of the plot points and the MMC.
