Billet engine anyone?

Got to have been a couple of grand just for the titanium machined fins! Th machining time on the alone must have been a few hours!
 
WTF :eek:

That is mental! The work that must have gone into that is just mind boggling! It all looks so good I'd not want to use it.

Wow, but why would they make the block out of Aluminium?

Why not, it's light and plenty of other engines made of it, guessing the cost to make that from titanium would just be obscene.

i know sod all about the metals mentioned in that thread. Whats so special about billet aluminium ?

I could well be wrong as I know pretty much sod all as well, but machining something out of a solid block of metal will give you something stronger than something that has been melted down and cast. I think.

Plus it's pretty awesome from an enigeering point of view to have a 'unibody' engine block, as Apple would call it :p

As said, I could be wrong though!
 
Most engine parts are machined from casting. Cast metals tend to have a different grain structure, and can be full of inclusions (including glass, sand, porosity, air bubbles etc). These will only be visible on machining, or non-destructive testing methods (Such as ultrasonic testing and dye pen) and it is not possible to check every part of the material. Plus, the closer grain of aluminium billet gives it a better strength as it is made from a single piece.
 
Yes much stronger than a cast lump, aluminium is also an excellent heat sink, when did you last see a steel cpu cooler.

The cost would be biblical, over 100k on the engine I would guess.
 
I had such a nice and complex reply all typed out, but I thought I'd refresh just to make sure I hadn't been beaten to it. There were about 10 new posts explaining why a billet aluminium block would be awesome :mad: damn you all :p

Does he work for a CNC company? That's the only way this is even remotely viable isn't it?
 
The vortex throws throws some BS claims into the mix, Ti for a crankshaft for example?
Good to know the real story, or more info on the builder, apparently lots of claims but no end results?
 
It's important to remember that this is for race/competition/conceptual use as as such, its reliability is lower, maintainance required is far higher and its life is comparably very short.

I know my mate's allumium billet con rods on his drag engine have a maximum life of a day or two, if not a few runs.
