timing....advance.....what? help.......
How much can we advance our timing for an N/A engine to make some more power.....what are the pros and cons? How much power? Thanks guys

You advance the timing by turning the CAS clockwise. Youll need to run higher octane gas if you advance your timing more than a few degrees. But it gives you more power, especially in the low end.

i see, that sounds nice. Just a little turn, not a big one I dont wanna run higher octance gas, my car goes threw gas like i drink coca-cola, 10 bucks a day! i drive ALOT how many degrees can i turn it?

I thought n/as couldn't detonate.

N/a's can detonate just as easily as a TII. The difference is the chamber pressures are much lower, and n/a's dont blow when they detonate.
Looking back, I had VERY minor detonation around the turque peak. I could never hear it, but you could feel a very slight loss in power. Thats the easiest way to tell if you went to far. If your engine seems a little less powerful then before in the midrange, back your timing off a little. But it wont kill the motor. But I didnt realize that when I was running that much timing.
Also, my intake temps were sky high due to where my air filter *was*. This was causing the ECU to back the timing way off. Advancing the timing helped my car A LOT then, but I had to run high octane. Now that I look back, I realize that I wasnt advancing the timing as much as I had thought, because the base maps were retarded from the high intake temps.
I havent tried to run 93 octane with 100 degrees advance since I moved my air filter(which fixed the above problem), but Im safely running about 7 degrees advance on 89 octane. And you can ask Justin(rx7impreza), my car RUNS.
Quick re-cap: advancing the timing in a n/a WILL NOT make you detonate enough to blow a motor. Im sure someone is going to try to prove me wrong, but you cant do it without pulling the CAS, and re-aligning the internals for more advancement of the timing. And I dont know if your car would even run with the timing advanced enough to blow the motor.

There are NO marks on my pulley...is there a way I can still adjust the timing (both the red and yellow marks are gone...many years have past I guess since it's now 16 years old...). ANY help would be more than appreciated!
