I call Bullplop on this one, although the billet stuff is pretty lush I gots to admit, this bit beryllium pistons is balderdash. looks like shiny parts put together for show with no intention of running it. titanium isnt good for metal to metal stuff either if I'm thinking right. blingy but not likely to work. and beryllium......... According to a very quick google Ilmor has manufactured pistons from an aluminum-beryllium alloy Since 1998

Erm, you're wrong. It'll be an aluminium-beryllium alloy. Actually quite commonly used in pistons. Very high thermal conductivity and low density for its strength. Banned by the FIA in 2001 to reduce costs and manufacturing health hazards (or because it was giving Mercedes engines an advantage over the Ferraris... you choose). The titanium wont be touching any metal unless things go wrong, thats what engine oil is for... Everything that Adam said, +1. Beralcast 191 beryllium aluminium casting alloy, for example (the only one I happen to have technical information on lying around the house ;D ), is half the density of titanium (2182 vs. 4451 kg/m 3), twice as strong in shear, eight times better at conducting heat, but frightfully expensive at nearly £280/kg (vs approx. £50/kg for titanium (2007 prices)). And it kills you. And the titanium won't be touching anything even without oil, as it's all DLC-coated (diamond-like coating): ultra-low friction, ultra-hard synthetic diamond deposited on the bearing faces for ultra-amounts of money Back to the rest of the stuff in hand, that's just silly. Like, awesome, Six Million Dollar Man silly ;D. Pushing the design of engine as far as it will go. There are definitely cheaper, more efficient ways of getting that much power, but there's just something about creating the ultimate iteration of an engine or car or whatever that I find deeply satisfying even to look at. A lot of respect.

1989 Peugeot 205. You know, the one that was parked in a ditch on the campsite at RRG'17... the glass is always full. but the ratio of air to water may vary.

i was under the impression that berylium was highly toxic and one of the rarest metals on earth, therefore ridiculously expensive, potentially hazardous to work with and not worth doing, could use ceramic pistons or some such? does galling not happen with titanium?
first thing i thought, other than nice machining on the block etc was the use of shiney stuff, made me think of when everyone was all about carbon fibre, regardless of what it did or didnt do. adding it everywhere for the sake of it.
anyways, thats my take on it. doesnt seem too likely to me, looks like there is more show boating going on than anything. sorry to sound negative, not intentional.

(the only one I happen to have technical information on lying around the house) I'm glad I'm not the only one that finds information like that scattered around their house

Beryllium is very toxic, and that was one of the reasons it was banned in F1, as the metals transfer into the oil, when Engines let go they create a severe health hazard to the marshals during clean-up, and probably would leech into the ground water if the oil drained into grass or gravel traps, I looked into using Ti valves in my engine, the big problem with Ti it is quite abrasive, there are 2 common valve guides available for Ti valves and seats, Ti and Copper beryllium, I did aquire a bar of CuBe but decided against the idea of machining the stuff. I suppose if Ti valves can run in Ti guides, there is probably no reason that rods and cranks cant run together, the only problem I can see is without running bearings, one tiny pickup on crank or rods is one expensive problem

Atmo V8 Power . No slicks , No gas + No bits missing . Doing it in style. Austin A35van, very different------- but still doing it in style, going to be a funmoble

Did they machine that block themselves? looks a lot like one I have seen being produced by an Austrailian company whose name escapes me.

could use ceramic pistons or some such?. The newest invention are carbon-auminium (yes) pistons. Very light, very heat resistant and very good in self-lubrication. But a bit problematic to use since they hardly expand... Anyway... The goal for 1000BHP per liter is very extreme. Some V8s have seen this number (2000BHP), but with multitude of cubic capacity. I guess extreme power figures need extreme materials. Like titan, berylium and what not ;D
