Alfa twincam "Nord" engine - the one they used from the 50s to the 90s - sort of like the small block Chevy! 900, 1100, 1300, 1500, 1600, 1750, 2000cc. Designed by Giuseppe Busso.
Alloy block & head.
Forged crank.
Wet cast iron cylinder sleeves.
Hemispherical combustion chambers with central spark plug.
Double row timing chain.
Direct valve actuation.

The straight 6 Mercedes engines from the '70s used much the same design. Double over head cams driven by chain, hemispherical pistons, central spark plugs, a single 4 barrel carburetor, and cross flow manifolds with cast iron stubby headers. Even with standard exhaust it started to sing at about 70 MPH. I remember fondly a trip across eastern New Mexico in the 1980's.BlackBart wrote: ↑11 Nov 2020, 13:21 Alfa twincam "Nord" engine - the one they used from the 50s to the 90s - sort of like the small block Chevy! 900, 1100, 1300, 1500, 1600, 1750, 2000cc.

Besides the performance of the car (top speed of 240mph), the video has something unique in it - the chief designer Norbert Singer shares a few mechanical difficulties when designing such high performance vehicle.

Old magazines....
Two different 12 cylinder Ferrari variations at Monaco. Imagine showing up at a race with two completely different blocks. Look at those ridiculous "roll bars."
But Stirling Moss still won...
The great Targa Florio in Sicily. 45 mile laps through the mountains and narrow road towns. This is where the Porsche Targa name came from - as a tribute to this race. It ran 1906 to 1973, minus wars, and when cars became too fast in the 70s it was deemed too dangerous to spectators standing on the roads. It was the most important race in Europe before Le Mans and the Mille Miglia. The course was everything from a single 90 mile loop, to a complete tour around the island (16 hours), to several variations of laps twisting through the mountains. It was run like a time trial, one car leaving every 15 seconds. The winning cars over the years included Fiat, Peugeot, Alfa Romeo, Bugatti, Lancia, Maserati, Ferrari, Mercedes Benz, Porsche, and others. It favored small, light cars. The record lap was a Porsche 908 averaging 128mph.
F1 safety priorities
Dan Gurney in his F1 Porsche, and Jim Clark
Rear engined cars take over at Indianapolis - a change in eras. Ford Indy V8.
Targa Florido again. All on narrow public roads with only stone guardrails if at all. It beat cars and drivers up.
These concrete pit buildings are still there - you can find them on streetview.
Daytona on the beach!

The Alfa Romeo Tipo 33 Stradale (road). The road-going version of the T33 race car. A little 2 liter aluminum V8 that spun to 10,000 rpm. They only built a handful, and they have variations in looks - some have single headlights, some have four stacked like a 917 behind the bubbles.

Some cheeky Ozzies have a take on the 1300 single-carb Giulietta Sprint and Alfa Romeo history. A very modern car for mid-50s design and engineering. Then there were dual Weber hotrod Veloce versions, and all-aluminum lightweights.

I don't really follow Formula 1 anymore - it's such a parade which consistently finishes in the order of budgets...Mercedes 1 & 2, Ferrari 3 & 4, Red Bull 5 & 6...
But did anyone see this violent, horrific crash last weekend? Unbelievable. I'm glad I was just watching a highlight reel and already knew the outcome. Romain Grosjean, driving for the American HAAS team, was inside this fireball for 20 seconds, managed to climb out himself. He bruised his ribs and burned the back of his hands. The new fire suit rules were increased just this year from 10 seconds of protection to 20 seconds. The new titanium halo in front of the drivers head saved his life as the car sliced right through the steel Armco barrier. Many drivers were killed this way in the 60s and 70s.
The car ripped in half - the driver's compartment went through the steel guardrail and as the fuel cell was ripped open and exploded, the rear went on down the track.
The doctors who follow the cars in the hotrod medical car for the first lap were there in seconds, and reached into the flames to pull him out. They have no full fire suit nor face protection. Course marshals blasted the fire with extinguishers aimed at his body. He lost one boot, and he couldn't see out of his melting visor.
In extreme twisting impacts and torque loadings like this (53g's they're saying!), the engine and rear suspension are supposed to shear off, so that's ok. But Armco barriers (these look like old fashioned freeway guardrails, stacked) are an outdated relic of the 70s and should never be used on a track like this. The pointy nose goes right between the first and second layer of railing. A super strong carbon tub at 140mph can pierce steel.
There hasn't been a crash and big fuel fire for maybe 20 years. The cars are so much safer now. In the 60s every crash was a big fire, and it killed many people. Look at what happened to Niki Lauda. Still, very troubling to see.
