A.C.E Water Injection KIT (GR Supra)

One of the new technologies, "water injection system", is a system that injects water inside the engine, but the purpose of injecting water is to cool the engine.

When an engine brings heat, it In sports driving and driving on a circuit, the water temperature and intake air temperature tend to rise because the engine is frequently used in the high speed range, and when the temperature exceeds a certain With this, even the tuning will not be able to achieve the desired performance .
With this, even the tuning will not be able to achieve the desired performance.
This is the so-called "heat sagging", but I think you may have felt the output decrease due to this heat sagging.

Various measures are taken to prevent heat dripping, and one of them is water injection.

The mechanism of water injection is to inject atomized "water" into the intake pipe just before the fuel is ignited, and cool it by the heat of vaporization ..
Generally, the fuel sprayed by the injector is vaporized to play a role, and direct cooling of the combustion chamber is also important in terms of suppressing heat damage to the pistons and cylinders.
In addition, by adding water to the fuel and injecting it during acceleration or high-speed driving, the fuel used for cooling is saved and it contributes to improved fuel efficiency.

In particular, GR Supra uses a water-cooled intercooler, and the intake We developed it because it was noticeable.
As a result, the water injection has significantly reduced the output reduction due to heat sagging, making it possible to achieve the desired performance for a long time.

* With the GR Supra of our demo car installed, the highest speed test in Japan recorded 289.27 km / h (as of R2 / 9)
There is no need to worry about rust because all the injected water evaporates before the engine burns and is discharged together with the exhaust gas.

This set includes a removable throttle spacer for GR Supra, and the throttle spacer has two NPT screw holes, so you can take it out of the intake pipe by installing an additional meter, or install water injection or NOS. Is possible.
