Besides a slightly muted sound and an uncharacteristic instant lump of torque, you’d be hard pressed to tell that a Ferrari 488 was turbocharged based on “lag”. That engine, however, is nowhere near the limits of what it can do. The new GT2 RS is a different story. A near-on 700bhp clout achieved with seriously heavy turbocharging and you can hear it in the way it runs through the revs. There’s a definite surge as they huff into life. Old school turbocharging could only live on in the modern age in the most extreme of cars and who better to wring it out at the Festival of Speed presented by Mastercard than rally legend Walter Röhrl.
