I don’t know the exact date they started production but the Jetfire was introduced mid-way through the 1962 year. You probably have one of the earliest cars.
This engine has very high compression for a turbocharged engine (10.25:1)and was meant to run with the alcohol/water injection system to stop detonation. I would’t run it if it were mine, at least not hard. I was told by a machinist that detonation (knocking) is muffled somewhat by an aluminum block versus a cast iron one. You could be doing damage you may not know about yet. On the other hand if the turbo isn’t building any boost, you are basically running normally a aspirated engine with a one-barrel carburetor through a turbo that isn’t turning. I’m sure it’s not very efficient but shouldn’t be detonating under those circumstances. I wouldn’t think it would be doing any damage to the turbo itself though. Maybe Jim Noel or someone else could give you a better answer.
