How many degrees in timing advance until it should begin to 'ping'??? I just wanted to know what the max base timing would be until a motor would ping. I am going to do an experimanet here. It's possible that my cam is not indexed properly. I usually set my base timing to 12 degrees, but the motor doesn't respond like it should. You can't always trust a balancer or timing marker. My balancer is new and timing markers don't move so..... I'm gonna try to eyeball whatever figure you guys give me and advance it that much. I was thinking that 16-18 degrees of base timing should make a car ping like a bastard, providing the distributor is set so that total timing is 36 degrees at base timing of 12 degrees (24 degrees of distributor advance.) That would give me 40-42 degrees of total timing. |
It varies from one motor to another. Every motor is different, once they've been modified. Just experiment. Set it to where it runs, advance it a little and see if it pings, if not, advance it some more, etc. until it pings, then back it off until it quits. |
I need #'s here... I need experienced, educated guesses. Look at my sig for the 91' and tell me what you guys think. |
advance your timing til you hear ping and then back it off a few degrees. i've been running aout 16 on my engine with no problems, if it's below 12 it'll diesel |
RB gave you the BEST advice anyone can give! It is the old "ear method" and it works every time :nod: Keep moving it counterclockwise. Take it for a hard spin. If it pings move the distibutor a couple degrees clockwise. If it doesn't, just keep going counterclockwise until it does, and then take two degrees out. My 305 has 18* of initial advance but is a vacuum setup. Most cc distributors are set around 4* to 6* at the factory but you can go further than that ;) |
It's subjective. Every single one is different. I found that I didn't ping until 10* or so, but felt a that the car ran a little better at 6* Conservative I know, but the car starts and shuts off better and doesn't get as hot. So the only way you can tell is to start at say 8* and work your way up. But for someone to say it won't ping unti 10* is just foolish advice! |
advance your timing til you hear ping and then back it off a few degrees. i've been running aout 16 on my engine with no problems, if it's below 12 it'll diesel I'm sure that your cars are awesome, but get a website. There's no need for a signature that long, especially when it is listed after every post! Get a website and have your signature be the link. |
Kind of interesting... Gruevb: I have a very similiar setup on my 84' w/L69. I run 12 degrees of base timing and 22 degrees of distributor advance. You were pinging with 10 degrees??? How much Distributor advence u got?????? |
I was pinging at 10* under certain conditions, and at 12, pretty consistently under part throttle. Not sure exactly what my total advance is as I've just got a cheap timing gun. :mad: |
