Quite possibly water methanol injection or perhaps nitrous oxide injection.

I’m thinking water methanol. I vague memory of that conversation when he did his AuDHD thing and over explained something. Ask a simple polite question, get a 30+ minute answer as Dad points at stuff under the hood.

You can get a bit of a boost from it, though not much on a naturally aspirated engine.
We had water/meth injection on the turboprop freighters I used to fly and it would make a huge difference. The engineers could vary the flow of the pumps and one plane that I flew (VH-UZY) had them cranked right up.
You had to move the throttles up to about 50% power before hitting the water/meth switch or you ran the risk of over-torqueing the gearbox, with the limit being 2,206 lb-ft.
I’d hit the switch at 800 lb-ft and the torque would jump up to 1,500 lb-ft. Bloody great fun.

That’s nice.
He’d use it to boost the power when overtaking other cars. I remember Mother clutching her seat belt and saying with increasing panic…Hans, Hans, HANS!!!
