I read time and time again that a turbo wasn't just a bolt on kit …
Porsche did this brilliant magazine advert when they launched the 944 Turbo:
Here’s the full text, since it’s quite small there:
Quote:
The theory that a whole is greater than the sum of its parts did not originate with Professor Porsche.
But he, for one, wholeheartedly subscribes to it.
Because if he’s learned anything in four decades of building cars, it’s that a change in one component can profoundly affect the performance of the others. And ultimately, the performance of the whole car.
Nowhere is this more evident than in the area of turbocharging.
Porsche pioneered this technology for production cars back in 1975. And realised from the start that simply bolting on a turbocharger, tweaking the engine a little and re-naming the car was the wrong way to go about it.
The right way is revealed below.
Every component shown here was deemed necessary to transform a normally-aspirated 944 into a turbocharged 944.
Major engine components, more then 30 in all, to compensate for increased internal loads and heat.
Chassis components, from shock absorbers and brakes to wheels and tyres, to meet higher performance demands.
Front and rear body components, to improve wind resistance at higher speeds, while controlling lift and drag.
To say nothing of the turbocharger itself which, among other innovative bits of technology, includes two water cooling systems to protect turbine bearings, even after the engine is turned off.
Of course, if we hadn’t gone to such lengths with the 944, we could still have built a turbo.
We just couldn’t have built a Porsche.
Ugh. I really dislike that American style of advertising copy, where they start loads of sentences with ‘And’.
