RE: Aviation fuel for the CJ?
By Martin Edridge - 11/12/2001 8:51:42 AM; IP 195.194.51.129
I used to struggle with detonation in my 460, tried avgas, additives and retarded ignition. I know it's a diffenrent engine, but the principles are the same. AVgas and additives are expensive and inconvenient and some additives don't work anyway. Pulling the timing down cured the detonation but also killed the power. Then I made my first water injection system, very crude and linked to (near) full throttle but I was soon convinced that this was the way to do it! Timing can be at optimum and fuel quality can be 'everyday' so this is the best of both worlds. The water also helps keep the chambers clean which in turn helps prevent ping. I made better systems since, but without boring you, the best thing is to just buy one of the better quality systems available. When it's done properly, there is no loss of power and some say it even improves but anything which kills detonation and runs for free (water!) has to be good.
Cheers, Martin.
