HKS GT Supercharger: Part 2

Keisuke Morita Tunes Our FR-S On The Dyno At Evasive, Coaxes A Nearly 30-percent Jump In Peak Power

By Bob Hernandez

December 17, 2012

We left off from Part 1 of this story having installed HKS’s GT Supercharger kit in Garage-FR-S’s project car. The intercooled system shoves a few psi of boost pressure into the intake but necessitates a proper tune before it can be used to its fullest potential, primarily to tweak the included F-CON iS piggyback fuel and ignition timing controller.

We went back to Evasive Motorsports to use its Mustang dynamometer, the same dyno we’ve been testing on throughout this upgrade odyssey. Keisuke Morita from HKS manned the laptop, seeking out the best parameters to milk the most out of the blown 4U-GSE boxer motor while keeping it drivable.

After a couple hours Morita-san did just that, in the process making gains – some robust – throughout the rev range.

The biggest jump in horsepower happened between 5,400rpm and 6,250, where it peaked at 201hp, a gain of about 50 over stock. The largest peak gain was at 5,940rpm, where the FR-S picked up some 55 horses.

Torque showed similar improvements, the system surprisingly eliminating the dip we saw early in the power band in nearly every dyno session up to now. A fat bump is situated between 5,100rpm and 6,360, maxing out with 176 lb.-ft. at 5,520, a gain of roughly 50 lb.-ft.

In terms of percentages, the kit makes in the ballpark of 28 percent more power. While some may frown at the peak numbers of 201hp and 176 lb.-ft. of torque, things should be kept in perspective.

For starters, HKS wants to make sure everyone understands the kit is still in development, with ours one of only a few in use. Further tuning and even pulleys that provide still more boost are on the horizon.

Secondly, the blower is irrefutably making the FR-S more powerful, and therefore improving its critical power-to-weight ratio. The manual transmissioned RWD Scion weighs 2,758 lbs., making its stock p-to-w around 17.7lbs. per horsepower (lbs./hp). The power made by the supercharger lowers that figure to 13.7lbs./hp, giving our FR-S a power to weight similar to that of the much respected Mazda RX-8, among other sports cars.

Shoulda went yellow but I like it!

I thought of a Backwoods Hillbilly with one tooth though when I saw the front mount off to the side...lol

Love the color for sure!!

those lips looks a lot better in black than color matching

Stock RX-8 makes around 170-180 rwhp and weighs 3,051 lbs. That is a worse P:W ratio than your HKS blown FR-S at 200 rwhp and 2,750 lbs.

Yeah i feel like the FR-S is a greater car then a RX8. That is garage fr-s article. But visit the site it has some great reads!

@Evasive Motorsports, would that FR-S be able to pass smog with those upgrades? MA has more or less the same emissions laws as related to new vehicles. I'm a little wary of removing the primary cat for a header...

I think that kit has got a ways to go if HKS expects to sell any. I for one would not pay $6,000+ for a supercharger only to pick up 50hp. Especially considering the Vortech kit is making around 245whp (other factors possibly being different, dyno, exhaust, tuning, temperature/altitude yada yada), and let's not even talk about the turbo kits. All I'm saying is that if they want to separate my wallet of that much money, they'd better get more ponies squeezed outta that thing. Nothing against you guys of course. You're doing a brilliant job! And the Garage FR-S looks fantastic

I ran the Vortech chargers on my car before. I broken 3 bearings on that charger. Vortech has only released the tuner kit so no ecu system. when they do release the full kit which is going to be like the $5000 range.


Also those number are on a dynapack. Evasive Mustang dyno reads a lot lower then a dynapack because its a roller dyno instead of bolting on the hub of the wheels.

Rocket Bunny and the color combo ftw!
