Look at the horsepower...

[megz]

They were qualifying engines, there is no way they could have made an engine strong enoguh to withstand those sorts of stresses for a complete Grand Prix distance.

Yep driver had to do his lap and immediatly come back into his box. Then staff poured water on the turbo parts in order to cool it and change it before the next 3-lap run...

[Edis]

So I thought in the mid 80s they had around 1400 ps?

I think they had about 1200-1300 hp before the boost restrictions came into play. But in the races they only had about 800-1000 hp. Less in the early eighties.

Although it should be mentioned that the turbo engines were a bit slower than the power figures indicated. Clearly they had a bit of a negative impact on the package as a whole. But once the power began to clearly exceed that of the naturally aspiranted engines they were faster and became a "must have".

You sure of that?? What I learned in school is that pooring cool liquid on hot metal parts was really bad for them... No?

That got me wondering; when did the cooling fans [leaf blowers] become the norm for when the car comes back into the garage??

That was the first thing that came to my mind when I read that. Sounds like a recipie for exploding turbos to me.

Did you guys miss the "and change it" part?

[strad]

They didn't give a damn about the effect on the parts as they went into the garbage anyway. They had whole throw away engines, let alone disposable turbos.

Not exactly recent info but worth taking a look anyway.

The Monografia 30 is the transcription of a conference with Mauro Forghieri held at Politecnico di Milano back in 1996 (just click on title to download).

Text is obviously in Italian so unfortunately few of you will be able to read it, the juicy stuff though is in the Allegato, that contains dyno sheets, data (power is indicated as kW on the pre-printed sheet, but the hand written numbers are surely in cv), and blueprints of the various engines.

On the same pages you can find also lot of other interesting stuff, if you can read Italian

I was more thinking the act of pouring cold water on a turbo that is 700-1000C. The rapid cooling will put the metal under massive stress.

If you've ever seen a Turbo fire (admittedly hotter than 1000C) and a marshal squirting water at it, you'll know what I mean. Effing great big shards of shattered turbo going everywhere.
