Want to see inside an F1 V10?

Amazing detail here, I've been reading the cylinder head part. very impressed

Is that really an F1 head? The casting and machining quality look crap.

You think? It looks exactly fit for purpose, look how perfect the components are.

that can't be one of the last V10's at only 15K rpm and 850 bhp thats more likely to be 3.5 ltr engine from the early 90's

towards the end these things were 18K+ and well over 900 bhp from 3.0 ltrs

I was commenting on the casting, and the machining of the casting, not the components. Some of the casting machining looks like it was done by a backstreet recon shop.

Having spent the past 25yrs making all sorts of parts for aircraft, nuclear submarines, nuclear power stations, plastic heart valves and CO2 detectors that are accurate to 5 parts in a million that ended up on board a shuttle mission...



















I thought exactly the same!

I worked in a foundry for ten years, and the last 6 or so I've been involved with manufacturing research/design. I've visited a lot of state of the art engineering facilites, including f1 teams, and seen (and made) a lot of very expensive parts.

I'd be surprised if that cylinder head was ever fitted in the back of an F1 car. Maybe a POC piece, but way below par for F1 IMO. The casting is full of flaws, and some of the facing operations look like they've had at least two attempts at getting it right. Bad show old boy.

Hart/Arrows V10 according to comments on the website (probably from a '98 Arrows A19?):

Maybe it was fitted to a car in that state after all ...

Have you not seen some of the rear machined parts around the brake ducts stuck on the Renault this year? I'd be ashamed if some of that stuff had come off my mill.

Renault engine brake ducts? you've lost me.

[PhillipM]

No, the rear of the Renault F1 car...

There isn't a Renault F1 car this year (unless I missed some name change somewhere along the line), but some cars have Renault engines.

Looking at that casting you can tell by the machining marks that the aluminium is of a st quality to use the correct technical term. Cheap and nasty castings are a bd to machine because either the aluminium sticks to the cutting tools or the foundry haven't cleaned the casting properly so the left over sand wears the tools out.

I'm sure I read somewhere that Cosworth used to pump their molten aluminium up into their mould using a pump from a nuclear power station so they could sand cast to die cast quality.

Also, why was the article making such a big deal over the valves being splayed radially? Honda were doing that with their RFVC engines back in the eighties and Rudge were doing it back in the 1930's ffs!

Certainly is an old engine, still impressive though as it was from a true independent.

After this year it is looking very unlikely F1 will ever have an independent engine manufacturer again?

Superb article here, so much information on what is probably a much underestimated engine.

Lotus?

[PhillipM]

Yeah, that one

Could it be a 1-off pre-production prototype? One to perform destructive strength tests, ensure clearances, access to valve stem seals etc? It looks like the everyday stuff I come across (but then I'm in the electronics side of engineering) fine for a development machine but lacking something special.
