B&B Automobiltechnik has thus boosted the power in several stages from 220 horse power and 350 Nm to up to 362 horse power and 510 Nm torque. Acceleration time from 0 to 100 k.p.h. drops in the strongest upgrade stage, from 6.4 to 5.2 seconds and the 0-200 k.p.h. value drops from 24.2 seconds in the standard production version even down to 17.1 seconds in stage 3. Maximum speed increases from 243 k.p.h. to 270 k.p.h.
The power upgrade portfolio begins with stage 1K for € 1,198: Modification of the electronics (minimum increase in charging air pressure and adaptation of the electronic injection parameters) is sufficient to get the 2.0 TSI engine to 280 horse power and 420 Nm. Moreover, stage 1S (€ 1,498) entails the processing and optimization of the air guides and suction paths thus producing 310 horse power and 450 Nm.
In stage 2 (326 horse power / 475 Nm / € 2,995), an enlarged and cross-section optimized special front exhaust pipe is installed, charging air pressure is increased by approximately 0.25 bar and the engine electronics adapted to such modifications.
Finally, for 362 horse power and 510 Nm torque, stage 3 entails a special high-pressure fuel pump and a modified air suction system and the company’s own sports exhaust system for the purpose of reducing exhaust counter-pressure and exhaust temperature. A high-performance charging air cooler and a special oil-cooling system ensure at all times that temperatures are well within the proper range. Adaptations are subsequently made in the area of suction and engine management. The price of the big performance stage is € 7,950.
To optimize the handling characteristics and the visual appearance of the Polo R WRC Street, B&B optionally offers a 20/30 millimeter set of sports springs (as from € 248) and a B&B coilover kit that is specially adapted to VW Polo R WRC Street and is height, compression and rebound-adjustable (as from € 1,798). There are also optional B&B stabilizers for front axle and rear axle for even more driving stability and minimum roll behavior in cornering (as from € 498). – See more at: http://www.seriouswheels.com/cars/2013/top-2013-BB-Automobiltechnik-Volkswagen-Polo-R-WRC-Street.html#sthash.wnipvOrq.dpuf
