A shameless image thread for the enginephiles

Still wonder why there's three pipes connecting the airbox to the shroud around the compressor. The outer two pipes are smaller than the center pipe. Thoughts? Might say cooling, BOV, or even a dual entry two-sided impeller. Think: one pipe to the front side as normal, and two pipes leading to the rear half. Triple entry, two-sided impeller.

I’m not seeing the 3 pipes... I am much more familiar with gas turbines and not jet engines, so I went looking for some info. I did find this nice YouTube video explaining the engine.

The pipe coming from the front is the starter air.

Perhaps some air cooling for the MGU-H or some oil cooler for the turbocharger?

It took me a bit but it's a one off from a company that recreates old cars. I thought it was a Bentley at first but noticed the NR on the front. Here's the description:

There was another section nearby for builders, and here I got to take in the details of the wild aero-car creation from Pur Sang. The Argentinian company is best known for their faithful recreations of ‘20s and ‘30s racing cars like the Bugatti 35, but this unique build, called the Pur Sang Nicola Romeo, is something else entirely. With a wild cocoon-like cabin set behind a WWI aircraft engine (a 14.7-liter Isotta Fraschini six-cylinder with 250-horsepower),

Always liked this one. Sequential turbo charging.

NA V12 6.5l 1000hp @11,100rpm designed by Cosworth for the Aston Martin Valkarie

[humble sabot]

The rear mounted cam drive is an interesting variation.
In the thread dedicated to the Valkyrie some people were saying it wasn't going to be possible to do 1000hp from 6.5L.
As the Pistonheads article said: Job jobbed!

What an awesome engine that is!

I just finished watching this epic 1 hour 22 minute video on top fuel engine rebuilds, it's long but really interesting imo.

To be fair, Lamborghini's 8.2 litre V12 from years back, claimed 1100hp at 7500rpm,
& proved strong enough to win many Class One off-shore boat-racing titles,
so a ~20% smaller engine, running @ 25% more revs, really ought to be able to match that power.



IMO, punting a big race boat - hard - could provide a good durability test for the Valkyrie mill, too.
