Daiichikan RX-7

'93

Dengeki Tuned!

HKS FD3S RS

Shocking speed! 1 minute 2 seconds 67

Rival Group A!!: The fastest tuned HKS FD3S RS in history!

At the end of 92nd year, HKS made an emergency call to this magazine!

On December 11, 1992, the editorial department received a phone call from HKS. The content was that HKS would be testing the FD3S RX-7 at the Tsukuba circuit, which was created by fully utilizing the technology that HKS had cultivated so far, so he wanted me to be there.

Since he contacted me like this, he must have a lot of confidence. The best lap of the Tuned RX-7 so far at Tsukuba is the Night Sports RX-7 on August 25th last year with a time of 1 minute 6.1 seconds. Can it be shortened? The editorial department immediately headed to the Tsukuba circuit with a cameraman.

At 7:00 am on December 16th, Hagiwara, who was behind the steering wheel of the Group A HKS GT-R, got into the RX-7 named "FD3S RS" and the test started. The RX-7 laps smoothly, with the high-pitched exhaust note that is unique to the rotary. And the time that was beaten out was 1 minute 2.67 seconds! Fastest done in HA in the past.

Even looking at the time attack, it was a good time to beat the fastest production car based on the N1 specification Falken GT-R (1 minute 2.85 seconds). I was very clear about this. Furthermore, as a result of changing to slick tires as a reference, the time was reduced to 1:01:30!

Showing such amazing speed As for the tuning specs, the 13B engine body remains normal, but HKS specializes in turbo tuning + suspension and dynamic system enhancements centering on the TA45S turbine. With this specification, the maximum boost is 1.2kg/cm at 460ps.. The boost pressure during the test was 1.0 to 1.1kg/cm and Mr. Hagiwara said, "If the settings are adjusted more, the time should be shortened."

This FD3S RS HKS was developed with the aim of being a fast and fun sports car that can be used from the street to the circuit. Can't wait for the release!

PIC CAPTIONS

The test was conducted with Advan A029R tyres on AVS wheels. Changing to slick tires improved the time by 1.37 seconds.

Commemorative photo of HKS staff after the test. I really can't wait for the release of FD3S RS

The RS starts up the first hairpin and accelerates. The rotary exhaust note was also very impressive.

engine: Equipped with a turbo-tuned TA45S full turbine kit from HKS, the output is slightly over 400ps. It's amazing that the engine body remains normal now.
