I bought my alcohol bulk from a oil supplier in the area. It was 100% Methanol. I then used the VP upper lube. I used it in the max amount recommended. I do not recall how much that was to mix in a barrel but it came in pint bottles and I know it was more than one pint per 55 gal barrel that I used.
I do not think you will ever hear the knock in detonation until the damage is already done. My friends engine was already terminal before he noticed anything. I believe it happens when the stop comes on and then goes back to full throttle.
I always made sure my Ron's Toilet was jetted rich and never lean. I also NEVER used the fuel shutoff valve to lean the engine during warmup before runs to warm up the engine quicker. I used the recommended individual runner jet size from Ron. I also put a small gasoline tank on the car and a small electric fuel pump to feed gasoline into the mainfold at the front and rear of the manifold through jets. I ran the engine on gas for a few minutes at race days end with the valve off on the alcohol system. That cleans all the alcohol from the upper cylinders and helps with the Methanols corrosive history. Before using the gasoline flush I did find cylinder etching during routine engine freshening. The gasoline can also be used to prime and start the engine and save the battery and starter. With Ron's setup and mechanical pump starting on alcohol is is little slow until the mechanical pump gets pressure up.
That is about all the hints I have for Ron's system. I have never run a carb setup so I have no experience there.
One last thing is be sure to get a good filter installed in the system and clean it regularly.
Ron's system worked well for me.
Good Luck With Your Setup
