Description

The spacer has two 1/8NPT screw holes, making it ideal for mounting various sensors, water injection, NOS, etc.
The water injection mechanism injects mist-like “water” into the intake pipe just before the fuel ignites, and cools it with the heat of vaporization.
Generally, this function is achieved by vaporizing the fuel sprayed by the injector, and directly cooling the combustion chamber is also important in the sense that it reduces thermal damage to the piston and cylinder.
In addition, adding water to the fuel and injecting it during acceleration or high-speed driving saves the fuel used for cooling and contributes to improving fuel efficiency.
In particular, the GR Supra uses a water-cooled intercooler, and the intake air temperature is easily affected by the water temperature, and the intake air temperature is more likely to rise than with an air-cooled intercooler, and the power loss due to heat sagging is noticeable during sports driving such as circuit driving, so we developed it.
As a result, the power loss due to heat sagging is significantly reduced by water injection, making it possible to perform the desired performance for a long time.
*The GR Supra demo car installed the system recorded a top speed of 289.27km/h (as of September 2020), the highest in Japan, in a top speed test.
When you hear that water is injected into the engine, you may wonder if the injected water will rust or cause engine troubles such as water hammer.
→No problem. The injected water evaporates before combustion in the engine and is discharged with the exhaust gas, so there is no need to worry about rust.
This set includes a detachable throttle spacer for the GR Supra, which has two NPT screw holes, allowing you to remove it from the intake pipe by installing an additional meter, or install water injection or NOS.
