TUBECAST UNLOCK FREE
It too is a very clever 'modular' system which also saves a lot of design work and indeed coolant flow analysis required in many cases where the coolant gallery is one large free form non-uniform shape within the head. Cores are bonded together to a total of five long and installed as a unit within the main sand moulds. It also offers the other advantage of the sand cores required to form the coolant gallery above the combustion chamber to be all the same thus requiring just one small core mould to form the entire coolant gallery within the head. This has the benefits of thermal uniformity in respect to coolant, oil, and combustion chamber temperatures along the entire casting. To put it in other words, the coolant gallery shape, volume, and architecture in general is exactly the same as its adjoining counterparts within the head. Internally the head also has the similar design features in that each combustion chamber and the coolant area directly above it as well as the valve actuation are identical on all five combustion chambers along the length of the head. This is something that makes a lot of sense and something that is not immediately apparent after initial analysis. This mirroring has many advantages in that it speeds design and production meaning only one head needs to be designed and not two separate head castings. It is important to note that both the right and left bank cylinder heads are identical castings - they are just machined at ends in different ways to make way for the cam gears and so on. The cam cover(not pictured) is also too a stressed member and it is these that provide location for the top fixing studs to the CF tub. It runs pneumatic valve train, has four valves per cylinder, barrel throttles, in-cam oiling, valve axis angled in both planes, bucket tappets, and cam cover coolant distribution. It's from a V10 engine making in the region of 850hp with a rpm limit of approx 15,000rpm. I had intended doing it last year but other stuff got in the way. Next year I hope to cast my first 16v cylinder head, doing everything from design, to mould making/pouring/machining etc, myself. Doing everything from Design, Costing, Pattern Making, and Machining. I have designed and made many parts mainly from cast aluminium. I have been researching all this stuff since I was young, and have continued to do so to the current day. I have also an extreme Interest in petrol n/a engines, and head design. I have a keen interest as well as experience in Motorsport as well as Aerospace, Metallurgy, and Mechanical Engineering. I asked for a token gift/wall poster given that this thread was a shocking amount of work to get it in a position where the info could be shared and understood easily by all and become a solid reference in time to come for anyone interested. I have chosen to hold back a few pictures of some pneumatic valve train parts since the site owners didn't reply to an email concerning this post a while back. If any reader wants to guess as to which car the head belongs to then guess away, but I will not admit to whether you are right or wrong. I am not going to mention the makers name all the same just in case I've missed some small print. I have read all disclaimers in reference to second hand F1 parts and what I am undertaking is legal. I do not work directly for any F1 company, and have acquired this head legally. To my knowledge, this is the first time this has been done in the public domain. You tend to learn nothing by just looking at pretty pictures in terms of Head design so you really have to get inside to unlock all. If you have a keen interest then this is the thread for you. I will be cutting sections from it, so anyone who is nervous, or cannot bare to see this sort of stuff cut up then leave now, its not the thread for you. Mainly, its construction, how it was made, and the parts inside and how they go together. In this post I will be unlocking a few secrets hidden within this part - cylinder head.
