A person I have known for many years operated the first dyno business in Cairns before he was devasted by MS.
If anyone knows, he would know, but I have not seen him for a few months, and I will definetly ask him next time we meet.
On one occassion when I had one of our vehicles at his business for a tune-up, he had a customer’s drag strip Mazda RX3 which had a turbo charger fitted to the rotary engine, and was being prepared for a drag meet in Townsville.
He said that it was running on 100% ethanol and the fuel line from the tank had been upgraded to 0.5". caoacity.
Way back when I was in high school, one of my best mates acquired an ex-racing go kart which was powered by a hotted up Villiers chainsaw engine.
We used to drive it along a dead end gravel road but some of the local “fun police” must have complained and the real police confiscated it .
When it was returned to him some time later, it would not start.
Apparently the boy racers at the local police station had attempted to drive it behind the station and had refilled the tank with Super petrol.
I do not recall what my mate said the fuel was but I assume it must have been ethanol aka Shell A., and after he drained and refilled the tank, the beast returned to life,
