Howerton Engineering carries some of the finest products available in the water injection industry. Below is a listing of most of the products we carry, if there is something your application requires that you don't see please don't hesitate to contact us.
Introducing the Aquamist HFS-4, the newest and most capable water/alcohol injection system in the world. The HFS-4 brings never before seen features to the water alcohol injection market. Some of these features are: Advanced direct injection circuitry, IDC-Boost Biasing, High pressure fuel pump compensation on direct injection cars, and advanced gauge mapping for a variety of jetting scenarios. All this is in addition to 100% methanol compatible valves, fittings and flow sensors. The HFS-4 is the gold standard of the water-methanol injection industry.
The HFS-3 ushers in an era of PWM-V technology at prices never before seen. Through years of R&D and perfection of the technology Aquamist has been able to offer a full featured kit at a very competitive price. A fully user configurable system with unmatched performance make the HFS-3 a great choice for nearly any application. With PWM valve injection, a full featured flow based failsafe, 100% methanol compatible valves and flow sensors, the HFS-3 is a outstanding product at a great price. Everything is included to run a two jet system except for a tank.
The HFS-2 offers many top features at a very competitive price. The HFS-2 has PWM valve injection, and the same controller features as the HFS-3. The HSF-2 system starts life as the HFS-3, then the gauge and flow sensor are deleted, and a multifunction dash switch is added. Priced in the same range as other manufacturers Pump Speed Injections systems, the HFS-2 is a giant leap forward in performance at a similar price. The HFS-2 is upgradeable to the HFS-3 after purchase with a kit from the factory. HFS-3 Pictured to Left.
Everything you need for a custom install is available. AN fittings, pre-compressor jet holders, heat sheilding, and much more.
The DDS3 is the best standalone failsafe system available. Using the same flowsensor and gauge unit as the HFS-3/4 kits, this unit is 100% methanol compatible and is a must have if tuning for the injection.
Custom, one-off tanks are available by special order. We have built many different arrangements for a variety of vehicles. A few examples are in this gallery.
Howerton Engineering constructs a line of standard tank systems for various cars. These are usually fitted specially to a vehicle, but are stocked as a standard unit.
