Rumors: Toyota Readying a Supercharged Version of the GT 86?

Toyota has repeatedly stressed that the GT 86 was developed as a pure, fun and easy to drive rear-wheel drive sports car, ignoring the horsepower race and concentrating instead on honing every detail of the chassis set-up.
In fact, the Japanese carmaker was so determined to stay true to its promise that it even included drift tests in its development program. The production model is said to have an estimated 0-100 km/h (0-62 mph) time of 6.8 seconds and a top speed of 230 km/h (143 mph).
However, almost everyone who has driven the 86 has found it lacking in oomph and, especially, low- and mid-range torque. In other words, you need to rev it hard to get the best out of it.
About a month ago, when the car was still known as the FT-86 and the first details were starting to leak into the web, we unveiled a Toyota Racing Development version of the car with a more aggressive bodykit.
Now, Autocar is reporting that Toyota chief engineer Tetsuo Tada has confirmed that TRD is indeed working on an even more powerful version of the GT 86 and prototypes are already being evaluated.
Despite the fact that Subaru, which provided the flat-four engine, employs turbocharging in its WRX and STi models, Tada said that he prefers supercharging as a way of increasing horsepower and low-end torque. That’s because, in contrast to turbocharging, it doesn’t affect throttle response of turbo lag nor the car’s drivability.
Supercharging has also been used in performance versions of previous Toyota models, such as the IS200, and as an aftermarket, TRD-developed power-enhancing accessory.
Toyota’s chief engineer wouldn’t reveal any numbers, but a 50HP increase in power should be easy.
