As the clock ticks down to the XGames (Don’t forget that we have our very own meet / caravan to the XGames) we get more and more juicy intel about the 2011 STi’s! Now these STi’s aren’t your typical showroom examples.
Of course the whole care has been race prepped with a spec cage and fuel cell. The most surprising element of this car is that it is running an EJ20 (per the rules… WRC Possibly?) instead of the factory EJ25 that we all love here stateside. Heck, I even run an EJ25 in my WRX! But it’s been able to push out an amazing 500hp and 560 ft/lbs of torque! That’s right! Out of a EJ20 with a restrictor plate! Enough fan-boy blabbering from me, check out the press release:
“Subaru Rally Team USA Debuts New 2011 Rally Cars at Speed with X Games Stars Travis Pastrana and Dave Mirra
— Cars will compete this Saturday at X Games 16 —
— Drivers Travis Pastrana, Dave Mirra and Sverre Isachsen pilot new 500-plus HP Subaru STI Rally Cars –
CHERRY HILL, N.J., July 29 — Subaru Rally Team USA unveiled its new 2011 Impreza WRX STI rally cars to journalists in dramatic fashion at the Pala Raceway in Pala, California. The team provided full speed ride-alongs to journalists during practice for the ESPN Summer X Games 16. Travis Pastrana, Dave Mirra and new teammate, European Rallycross Champion Sverre Isachsen, demonstrated that they were ready for the SuperRally X Game competitions, being held at the Los Angeles Coliseum on Saturday, July 31st.
“The team has worked very hard to get these vehicles ready for the X Games,” said Pastrana. “The competition is going to be tough but I am confident that our STIs will be the cars to beat.”
The team’s technical partner, Vermont SportsCar, first began with a stock 2011 Subaru Impreza WRX STI right off the showroom floor. The car’s interior was then stripped bare and the shell lightened then fully seam welded for added strength. A multipoint roll cage, manufactured from T45 steel, was then welded into place.
Major differences from the stock STI include the addition of a competition fuel cell — which keeps race fuel contained within a flexible Kevlar bag tank — and lightweight carbon/Kevlar RECARO SPA ProRacer competition seats (w/HANS- Head and Neck Restraint System). Other interior additions include a custom STI dashboard, carbon fiber door panels, a Coralba C-Giant Rally Odometer, and an onboard Fire Suppression System.
The stock dampers are swapped out for heavy-duty rally dampers made by EXE-TC competition suspension. The rally dampers are fully adjustable and are built to take the abuse that off-road gravel rallying entails. Under the hood sits a 2.0-liter, 4-cylinder, turbocharged and intercooled STI engine running VP Racing fuel and producing in excess of 500 horsepower and 560 lb/ft of torque (running with 45mm restrictor for X Games). The clutch is a high performance-racing clutch provided by EXedy. Launch control, a turbo anti-lag system and a hydraulic handbrake are just a few of the features at the driver’s disposal.
A 5-speed, close-ratio dog-engagement gearbox is used, which allows Subaru Rally Team USA drivers to shift without depressing the clutch. The DCCD (Driver Controlled Center Differential) is similar to the system in a stock STI street car, but with a competition ECU for the differential, which allows for greater control of the torque delivery between all four wheels.
The exterior of the car remains close to stock, with the simple addition of mud flaps and a 1/4-inch aluminum skid plate. A roof-mounted carbon fiber air scoop aids in cooling the cockpit and the stock rear wing is replaced with a larger vertically slotted wing, which greatly improves down force to the rear of the car, even as it slides sideways. Lastly, auxiliary HID driving lights, made by Vision-X and housed in carbon fiber light pod, are fitted for night rallying.
“Learning a new car can be a challenge,” Isachsen said, “but having seen the result of the Subaru team’s preparations and practiced in my STI, I am very much looking forward to driving in the X Games SuperRally. Though the ERC (European Rally Championship) is somewhat different from SuperRally, I think my experience will place me in a competitive position for this event.”
The SRT USA will again compete in the Rally Car competition, which they have won 9 out of the 13 possible medals in the past 4 years. The event features two rally cars at a time running on a stadium based parallel course. New for this year X Games will debut SuperRally, which is based on the European Rallycross. SuperRally features direct head-to-head competition with four cars at a time on a tight dirt course within the massive LA Coliseum, in downtown Los Angeles. The new format should prove especially exciting for America fans as the rally cars will bump, jump and slide together in a furious sprint of just a few short laps.
Subaru.com/Rally will post daily updates on the progress of Subaru Rally Team USA throughout X Games weekend.”
Everyone from Subie-life.com would like to wish the whole Subaru Rally Team America the best of luck and we’ll be cheering you on in the stands!
