It's worth noting that the Carrera/S have a totally different engine to thye GT3. More interesting though, Suzuki GSXR1000 has 185bhp from 1ltr without a hair dryer. Even better though, the BMW FI turbo cars had 1500 Bhp from 1.5ltrs with the boost wound up for qualifing!!! They were however hand grenades with the pins out!
