Check out Thomas Zurawski's channel. Very interesting seeing how the stock exhaust manifolds and inlets and turbos can be improved. Alas not for fitting to a Conti, the W12 is going into a camper van!

 

Agreed 100%,
I have been watching Thomas for a while, I like the idea of the blades in the intake for air flow.

And to add, a lot of the work Thomas did for increased power could be performed on our vehicles, such as all the porting and polishing of all the air intake runners, and the 2 airflow directors on each side of the intake.

Yes, he has a LOT of interesting stuff to say. I haven't watched all the videos yet, as I only found them last night, but initially I thought, oh my god WTF is this guy playing at? Then you realise he knows exactly what he's talking about!

The restrictive exhaust manifold was unbelieveable. Just one of his cylinder branches diameter was the same as the entire stock engine bank exhaust. I assume this is due to width limitiations seeing as the W12 is sooo w-i-d-e.

I also could not understand the wierd stock inlet plenum. Full of different size and shape ports and bad airflow surfaces. Surely that was done for a reason? Is the VW VR6 just as bad?

I will certainly be looking into VR6 remapping tools so see if these really are applicable to the W12...

 

Go to 6.15 for intake manifolds explained

 

Jeeez was that for 5 years olds?

Anyway the take home I got was different manifold lengths and cam profiles.

I guess there might be similar cross sectional areas but it sure looks odd:




Also odd that there is no trumpet shape to the inlet, just a sharp corner on the ports.

 

I feel almost let down and disappointed hearing how badly designed our cars are. But for those of us who have had Conti gt for some time will have stared to realise this .
The heat aspect ie melting glue and gaskets is a concern. I wonder if there is anything aftermarket that can be done to get more air into the engine bay for eg losing the windage tray, aftermarket bonnet vents. Aftermarket turbot heat shield wrap?

 

Everything is a compromise even in a luxury car. I guess there's just no room left either side of that mahoosive lump for better breathing manifolds. They use dinky turbos to get boost lower down the rev range.

I can't wait to see what the W12 does with decent turbos on it.
