Early F1 Turbo era

[Frank Musco]

Two very long videos of developing a turbo F1 engine. The videos show a 4 cylinder failing during testing around 16 minutes, (watch the look on the face of the test engineers, not happy, as well as how they were collecting data manually!), and the strip down and then development of a new v6 through to Alan Jones running it at its first race. I thought it was very interesting, especially if your into turbos.

Very intresting , i watched the whole of part one then i came across this http://www.youtube.com/watch?v=7UudXa3X_yY&playnext=1&list=PL0A53BCDE3578F3FB if your a 164 fan.

Frank you have way to much time on your hands you should be building a new motor. Or is the new motor turbocharged and you are wathing these clips as R&D. It was very interesting all the same

[Frank Musco]

Yes, I am using videos as these as R&D for future builds.

Therefore, any comments on the apparent lack of water passages across/through the deck surfaces of both the 4 and six cylinder engines? Does it have something to do with increasing the stiffness/decreasing distortion of the bolting surfaces in an effort to keep the liners sealed under extremes of pressure and vibration? Does the cylinder head have a separate cooling system to the block?

Also when the crank was being placed into the V6 block, the crank may have roller bearings on the main journals, as I didn't see a bearing shell in the main cap. If so, how is it fitted to the center journal? The big ends seem to have the traditional shells fitted, is that true? OR is it like motorbike engines which are roller bearings on the big and small ends as well as the mains? 

Also, are V6 engines less prone to Natural frequencies of vibration at high revs?

Thats awesome! thanks

That's a great find.  I love the dyno footage of the V6 where they're troubleshooting by oscilloscope!

The main bearings has me puzzled too, the end main looks like it could be a needle roller but that would mean the gear has to come off the end of the crankshaft and it doesn't look like it does.  No idea how the centre two mains would go on if they were needle rollers.  Maybe the crankshaft is in a few pieces and pressed together like a motorcycle?  I think you're right about the big ends, you can see the oil gallery holes in the big end journals when he installs the pistons and rods at 37:00. I think also it would be hard to make the piston oil squirters work with roller bearings in the big ends. 

In the foreground at 40:02 there's a passage between the head and block that's probably for coolant, as well as the ports at either end of the head next to the inlet(?) ports. At 34:22 there's 2 ports on the end of the block that could be for coolant as well

The main bearing puzzle starts from about 33:50 if anyone else wants to check it out

Cheers, Scott

2 awesome videos. It's amazing what they achieved such minimal technology by today's standards. No CAD programs and CNC machines back then (though the Americans had early CNC machines when they built the SR71 Blackbird plane in the '60s). Those early days of engine management systems were pretty impressive considering they appeared to have very little if any data logging capacity and processing power.
