saw this on facebook and thought it was worth a share,

I sure we all can apricate some nice cnc machine work , doesn't look like they have redone the cylinder head yet, they do tend to be a bit harder than a block ,

I'm not very good at the translation , but maybe Alan has some more info these ?

defiantly pretty cool !

I don't know much - if anything - about it, except that it was commissioned by a cashed-up customer of Number7.

Heaven knows how much that would cost, and somewhere there's a skipfull of swarf!

Looking at pics that have been coming through of the event, this caught my attention much more. A recreation of a period Works race team S20 engine made up from genuine Works parts collected by Yamazaki san. Lucas mechanical injection, dry sump, the whole bit. Wonderful!

@Albrecht Whats the bit ringed in the pic below? looks like a redundant distributor drive!

That's a drive take-off for the tachometer. Works S20 race engines had mechanical (cable) drive tachos.

If you look closely, you can see that the whole mechanical fuel injection system (Lucas pump and Lucas metering unit) is powered off the same single belt from that added tach drive unit, which in turn is driven (behind the front cover) by the same shaft which turns the distributor. Normally - on production engines - there would be an inspection cover there.

I have a mechanical tach drive on my KPGC10 which is driven off the same point, but was fabricated privately for the previous owner. It makes the tach needle behave very 'clockworky', if that makes sense. Kind of like an old Bugatti or something. They did it because you get less tach 'bounce', and it is supposedly more accurate.
 
I would love a billet block RB26. But its such crazy money.

All billet parts are beautiful to me.
