JB4 Universal Water/Methanol Injection (WMI) KitMake tremendous amounts of power on pump gas! Water Methanol Alcohol injection commonly referred to as WMI allows you to make tremendous amounts of power on pump gas. The effect is similar to running 100 octane race gas or E85 fuel all the time with the additional cooling benefits allowing for more power than you can make on race gas or E85 alone.

Make tremendous amounts of power on pump gas!

Water/Methanol/Alcohol injection commonly referred to as WMI allows you to make tremendous amounts of power on pump gas. The effect is similar to running 100 octane race gas or E85 fuel all the time with the additional cooling benefits allowing for more power than you can make on race gas or E85 alone.

FSB JB4 Water/Methanol Injection (WMI) controller

The BMS JB4 FSB Water/Methanol Injection (WMI) controller allows the JB4 to control your WMI pump and solenoid for dynamic progressive flow mapping. It also allows the JB4 to monitor pump current to overlay it with CANbus feedback for tuning parameters such as fuel trims and fuel pressure to provide a comprehensive flow-based safety system.


The key to a safe and effective Water/Methanol Injection (WMI) setup is tuning integration. All BMS kits integrate to the JB4 tuning system allowing for precise mapping based on boost, throttle position, engine speed, intake temperature, advance, gear, and other data elements available to the JB4 through its CANbus system. In addition, a pump flow signal is fed back to the JB4 allowing for a safe and smooth progressive boost mapping. If the tank runs empty or flow drops for any reason the JB4 will safely back down performance to avoid knock. In addition, WMI can be activated or disabled from the driver’s seat, will automatically disengage during traction control or safety map situations, and WMI flow data can be displayed in dash and/or via your JB4 Mobile logging device.

BMS kits include a high quality 220psi Aquatec WMI pump (the industry standard), methanol compatible solenoid with filter, compression fittings reducing the risk of dangerous leaks, and all required wiring and mounting hardware.

The base kit includes a WMI pump, solenoid, FSB for JB4 integration, WMI solenoid, filter, 20' of WMI line, and required fittings. Using the options when adding to cart you can add on a WMI nozzle (BM10 suggested for most applications), tank, and optional check valve tank tap to keep vapors inside the tank.

Optional check valve billet tank cap to keep vapors inside the tank is available at the bottom of the page

Injection Nozzle Options: (Single or Dual Nozzles)

The nozzles are determined by the intended power and how many bungs your charge pipe has. The nozzles are 1/8” NPT and screw into bungs included on most aftermarket charge pipes. Our "super atomizing" nozzles are well known for their great atomization and flow characteristics. The nozzle number represents the approximate gallons per hour of fluid when at full flow. Generally speaking, running two smaller nozzles is preferred to one larger nozzle for an equal flow to improve fluid atomization and distribution. Feel free to email us for nozzle advice if your situation is unique.

Saved my sanity
Size: Small: 24" x 24"
I thought I knew everything about cats, but when my 14 year old cat stopped using the litter box, I could not fix it. I did persuade her to start using puppy pads but the problem was she would pee toward the edge and it always got on the floor. Or, defying everything I know about reality, she would find a way to pee UNDER the puppy pad. I asked ChatGPT for advice and it recommended these. They fixed the problem by 80% and I'll take it! These mats help a ton. She still gets some pee on the floor, but it's not the huge problem it used to be. The edge on the mat keeps it contained. And enzymatic cleaner works its magic on the floor. The clips that go on the edges are kinda fragile, but that's why they give you extras.

It doesn’t stop leaks from the pee pad.
Size: X-Large: 28" x 34"
I’m trying to figure out how not to have leaks occasionally. I’m going to call the company to see if there’s something I should be doing.

Training pad holder literally rises above the competition
Size: 24"X24"
We have been through a variety of potty pad products during our housetraining journey with our Havanese pup. The Petphabet training pad holder has been the best by far and has ended our search for a number of reasons: Pros: 1. Grid design keeps puppy from chewing/tearing/destroying/eating the potty pad. 2. Size is perfect for our pup even as he is getting bigger (15 lbs) - mileage may vary for larger pups/dogs. 3. HERE IS THE REASON THIS PAD HOLDER STANDS OUT AMONG THE COMPETITION - The top grid is elevated off the surface layer where the pad lays, which allows an air gap between the standing surface and the potty pad. This allows the urine to fall to the pad without pooling and without your pup stepping in it and tracking it everywhere! Cons/Areas for improvement: 1. We like blue but it's not for everyone! 2. The "posts" holding the mesh up from the base carry all of the weight of the dog and in some cases jumping or playing on the pad holder can cause the edges of the posts to cut through the potty pad liner, causing a (minor) leak. I would recommend the manufacturer design any subsequent models with larger, flat surfaces on the post supports. 3. The 4 piece design means the base is not solid but has a split down the middle that is not waterproof. This can be remedied by caulking the 2 sides of the base together with clear silicone assuming you will no longer need to disassemble the unit. 4. Poo can get caught in the grid if your pup has loose stool. If not removed quickly your pup may step on it and really pack it in there. After many trials with other products, we are very happy with this training pad holder and have bought a total of 3 units for different areas of our house. I highly recommend for small dogs/pups!
