Dit is de snelste GT2 tot nu toe?
Switzer is een Amerikaanse tuner, anders dan de naam doet vermoeden. We kennen ze oa van de Porsche 997 SLEDGEHAMMER met 1000 pk, vergeleken daarmee lijkt deze GT2 een lieverdje. Dat klopt als we de woorden van eigenaar Tym Switzer mogen geloven, volgens hem is de GT2 heel beheersbaar: “the best part is that the car is still so manageable on the street, at this power level. It is an everyday hyper-performing exotic, and I can’t wait to get it out on the track and see how it performs in the hands of a pro driver.” Het 800 pk-package is echter wel gebaseerd op dezelfde techniek als de SLEDGEHAMMER.
Switzer’s 800 hp GT2 package makes use of custom Garret GT30R-based turbochargers with custom billet compressor wheels on ball-bearing center sections in lightweight stainless turbine housings. Switzer’s upgraded turbos compress massive amounts of air, while generating heat than the stock units – heat which is channeled to the engine through Switzer’s own MONSTER intercoolers. The engine itself is fed air and fuel through larger injectors and a custom intake plenum with an oversized throttle-body. All this hardware is managed by the stock ECU, running Switzer-specific DME software calibrations. Perhaps the most controversial part of Switzer’s package, however, is the exhaust system. Switzer’s GT2 exhales through a GT2-specific version of the company’s existing 997 TT exhaust. “As much as we would have liked to stick with the GT2’s titanium canister, there was just no way to hit our power goal on pump gas with the stock system. It was just too restrictive and not designed to handle this much airflow.”
Switzer’s stated goal for the GT2 project was 800 crank horsepower on 93 octane pump gas with an efficient, linear power curve that efficiently put power to the ground and didn’t punish the driver with sudden spikes in torque and power.
