RE: The M10 engine. What You May Not Know.

That was the day when qualifying engines didn't last as long as Qualifying tires. And there was no limit to the number of engines they could

use in one year (or weekend for that matter) They had 1300+ for Qualifying but turned them down to 850-900 for the race to make them live.

Remember they had to take their hand off the steering wheel to shift in those days and they had 5 speed gearboxes and shifted almost as many

times per lap as they do now with the paddle shift boxes (they also used the clutch and didn't left foot brake very much) Someone once said

driving F1 cars of this era was like sitting in front of a Semi-Controlled Nuclear Explosion.

I watched qualifying (and the race) for the 1981 Las Vegas GP. It was held in the parking lot at Ceaser's Palace, before all of the development! During qualifying there was something falling off the back of the cars on to the track. When I inquired that afternoon, I was informed that it was ice cubes! They packed ice around the turbocharger during qualifying so they could cool the intake charge and raise the boost. Always looking for the "unfair advantage"!

...well, and just keep the turbo alive for 2 laps...

 

The 'official' BMW quote on horsepower was that their dyno didn't read over approximately

1000 hp, (750 kW)  and that the qualifying tunes could peg it pretty handily...  before they

exploded...

 

1980's F1 racing turbos begat the wonderful '90's street turbos we got.

 

I wonder what the current dirt bike engine/electric forklift amalgamation generation will do for street cars.

Probably quite a bit, actually...

 

...but brake- by- wire scares me.  I don't even like the E46's

throttle- by- wire...

I'm curious whether the coatings in use now would have increased longevity. Ceramic on top of the pistons would have helped with heat/detonation. It seems there is some kind of magic film for every moving part! When I rebuild my turbo motor, it's getting all the internal help I can give it. Too bad they didn't intercool them!
