Turbos now are a world away from what they were. Things certainly ain't what they used to be, thankfully. I had a Lancia Y10 Turbo which was basically an Uno 60S engine with a turbo and intercooler. At 85bhp it was about 45% more powerful than the version it was derived from.
It was dog slow until the turbo kicked in and then all hell broke loose. With a 0-60 time of about 8.5 secs., it was about as quick as a XR3i. But if you take into account the fact that by the time the turbine started its work the Escort would already be 50 yards ahead, yet the White Hen would be with it by 60 mph.
Apart from the crude arrival of boost, in many ways, once you got used to it, it was actually a very useful device.
There was quite a long time when I would have gone for a larger engine and higher revs, but now, I'd go for a turbo car; at least if we are talking of the kind of motor that mere mortals would buy.
Spent an hour today on a road between the Airport and Wilmslow and with the exception of a couple of Bentley Continentals, the stars of the afternoon were a Ferrari F430 Spider and a Maserati Convertible. The sound of the Maser and F430 as they accelerated up the road was something else.
