My 91 Camaro RS is basically stock....The only thing I have done is a high folw cat. Is there any advantage if I advance the timing on my LO3? Just curious.....because I'm bored......

Thanks

are LO3s really respond well to a 4* advance of the timing...this is what i have planned to do to my baby once the f**kin' rain stops outside. (its been raining for like two weeks here in chicago!!!)

I would suggest you advance in 2 degree increments until you experience knock then retard a couple degrees. Run 93 octane too.

 

nope I wish I was the one doing the biting though

 

what should I expect by advancing the timing?

 

better combustion of gas = more horsepower!! and quicker 1/4 mile times!!

 

how hard is it to advance the timing? I've never seen it done so I have no idea how to do it. Well, I have a general idea, I did learn about engine timing back when I was in high school.....but that was freshman year.....

 

well seens my 89 camaro is old and has 135k miles on it my car timing is at 6 thats were it runs good now when i had it like at 10 and 12 advance man did it move it was crazy but it wastes more gas trust so stay regualr

 

I'm not worried about gas, belive me, my last ride got 7mpg. All I want is this thing to haul butt...

 

All you have to do is loosen the distributor slightly then turn it until you have avanced it as much as you would like. This is all with a timing light ofcourse. If you don't have one then don't even attempt it.

 

Coupla things......

When setting the base timing don't forget to temporarily disconnect the "timing wire" to elimimate all ECM-supplied advance. It gives some additional advance even at idle. It's a one-wire straight-through weatherpack connector popping out of the wiring harness over on top of the heater box under the hood. Wire is tan with a black stripe. Then have at it with the distributor wrench and timing light.

You won't "hear" detonation if you over-advance the timing becuase your motor has a knock sensor which will just pull the timing back if it hears detonation. Unfortuately, it'll pull out a BOATLOAD of timing if you get into detonation- far outweighing the performance you got from advancing the timing in the first place. So the old trick of advancing 2* at a time until you hear detonation doesn't really work well on knock-sensor equipped engines.

I have found that many GM TBI motors like the timing set at 4-6* BTDC instead of the stock 0* setting.

 

yeah, it seems that the TBI cars really like the 4*- 6* range, i have a moates adaptor, and i use the adjustment for timing, i usualy keep at at 4* with cheap gas, and 6 with not so cheap gas, that is where the motor seems to be happy.

 

When I was stock I was running 8 degrees advanced on 87 octane with no problems at all. I would stay at 6 unless you have a way to detect the knock(winALDL, Moates, etc...)

 

Awesome, thanks, I do have a timing light (well, my buddy does) so I'll give that a try.....just need to get the @#$! thing working again....
