Great vid, thanks for highlighting.A modern car that is genuinely exciting to see come together, absolutely love this project and really has that element of "special" that IMO none of the other current crop of super/hypercars have captured.

What a fantastic bit of kit.

. One question - the article mentions that timing chains wouldn't cope with the 11,000 RPM limiter, but most bike engines use chains, and often rev to 15,000+ RPM. Is this really the reason chains weren't selected?
Narrow range of rotational speed on bike engines and usually far smaller capacity means less vibration/torque etc on the chain? Can anyone put more meat on the bones of this statement?
"but that wasn't really the priority here, and if you want power rather than economy port injection is slightly better, and it also meant we didn't need a GPF."
I’d like to understand why. Why does port injection allow the GPF to go?

Sounds like a pre-turbo F1 car. Lovely.

The chains on a bike aren't 1.5m long turning four camshafts that are each 75cm long and opening 6 valvesOne question - the article mentions that timing chains wouldn't cope with the 11,000 RPM limiter, but most bike engines use chains, and often rev to 15,000+ RPM.

Port Injection can reduce particulate emissions, probably enough to comply with current regs. "but that wasn't really the priority here, and if you want power rather than economy port injection is slightly better, and it also meant we didn't need a GPF."

Direct injection allows lower CO2 but at the cost of higher particulates. Port injection gives lower particulates but at the cost of higher CO2...they don't care about CO2 for this car but there's legal requirements on particulates.
