Stage 3 - Polo WRC Final result

Before detailing the results, it is essential to recall the customer's expectations and the major modifications made during this stage 3 preparation. He wanted to obtain between 420 and 450 bhp while running on petrol. Here's what was changed on the Polo WRC:

• Complete forged engine: pistons, connecting rods, valve springs, valves, modified roller cam, everything to ensure maximum reliability.
• Optimised supercharging with a TTE 480 turbo.
• Full exhaust system: This system not only gives the Polo a distinctive sound, but also optimises the flow of air for enhanced performance.
• Tuned choke: This parameter, adjusted to suit the engine and turbo, contributes to an explosive sound while ensuring the car's stability.
• Adjusted chassis: An adjustment to the chassis to manage the added power and ensure vehicle safety.

These modifications give the Polo 6R WRC a higher level of performance, while maintaining a balance between performance and reliability for regular use.

The power bench test revealed figures in line with expectations. With 430bhp and 630Nm of torque, the Polo 6R WRC is propelled far beyond its original performance. With a constant power plateau right up to the ignition switch, it delivers acceleration and acceleration that will leave you on the edge of your seat.

A breaker that's more than there!

As well as a machine that runs hard, it has a sound that wakes you up. As soon as the car hits the ignition switch, it's a shooting gallery for the ears. It's a good thing that the owner won't be confronted with the ignition switch for road use.

The road test confirmed the Polo's increased performance, with the turbo charging from 2,200 rpm, offering instant power under acceleration. In terms of roadholding, however, owners will need to take a few precautions, as the car is likely to behave a little naughty on wet roads!

Fun fact about the project!

Throughout the project, it was impossible to find the anti-theft nut. William had to work without ever removing the rims to do all the engine and rear brake pads... Not the easiest job, but nothing insurmountable for our technician who specialises in high-flying stunts!

Such preparation represents a significant investment, costingaround €16,000 for all the modifications carried out at Shiftech. This sum covers a new, forged engine, plus all the necessary installations and adjustments, as well as customised mapping for Stage 3 to guarantee both performance and reliability.
