Should have based it off of he small block Ford, better cylinder heads design available.

Errr, this is a engine built from scratch. So they could use a canted valve head if they wanted. Which no end of Chevys have used over 25 years.

I must have commented on this elsewhere, impressive numbers but where do you find a transmission to live behind it, as well as where do you find an engine bay long enough to fit an over 4 foot long engine.

Even in a prototype Sports Car you are going to end up with a very long car and probably some very average handling as well.

 

There is a handmade Ford V12 using a Cleveland head. Blocks and heads welded together and custom crank and cam. Makes fairly good power but where will you fit it.

 

The other thing ofcourse with these very long engines is that you will be quite limited in camshaft as such a long one will twist and or break.

For a while Sprintcar engines were breaking cams regularly with lots of lift as well as driving all the accesories as well off the cam. P/S pump. wing pump water pump and oil pump. But no more drag than 32 rockers on a cam 4 feet long.

 

And an Australian mob making V12 LS as well. But they seem to be a Hot rod engine only. Coz it looks tough!

I don't know why that article is dated "NOV 6, 2017", when it is in fact much older.

Holy Moly, Batman!

I'm normally not much into such mammothness, but that is fabulous!

Perfect "getting around Miller's" kind of camp-mobile motor. ;-)

Here's another LS-based V16, but for marine use.

For its intended application it seems to make sense. And using  4 GM heads is also smart.

The other one is better and makes more hp at probably a large cost. This one should be considerably cheaper.

I do not like the gun drilled cam though, an accident waiting to happen even with conservative spring pressure.  A very long piece and I feel the achilles heel of all of these very long engines. It seems they have the crank supported very well though again very long. An d probably not ideal over say 6000 rpm.

So three versions - 2,000 hp, 3,000 hp and 5,000 hp. I have a question - why no 6,000 hp version?

 

I mean if its just about measuring dicks, you need to have the biggest.

Hang on, if I understand the claim correctly, it is that 5000 hp can be obtained from a 12.3 liter engine. 

 

I don't think so. 

 

At 36 psig boost, and 100% volumetric efficiency, a 12.3 liter engine at 6900 erpm will flow around 242 lb/min of air.  For a gasoline engine, this means around 2420hp (typically you can get about 10hp per 1 lb/min of air since you must be near stoichiometric).  You can certainly flow 61lb/min through a single 81mm turbo (so, 242 lb/min thru 4 in parallel).  But that is at choke and you couldn't get 500/4 = 125 lb/min out of four turbos that small. 

 

But the main issue is the size of the engine and the max speed which is going to limit the max power no matter what.

Good point Gerry! Maybe they are running 87 psi boost.  :stoned:
