As OG says - there's no easy way to compare and provide an accurate ratio.

As for 1980's F1 cars, it's true the turbo's were limited to 1500cc but then the engine only had to last one race before a rebuild so it didn't matter if you ran at 24,000rpm with 3 bar of boost.

No manufacturer would consider this kind of brutal treatment for a road car.

Furthermore, the economy was not an issue as there weren't significant fuel limits. It was commonplace to overfuel the engine to reduce combustion chamber temperatures.

I'll stick to my guns though. If you have 200bhp on tap and use all of it all the time then you will burn fuel, whether it's diesel, petrol, NATASP or forced. There's no free ride really.
