I don’t understand how you can advance/retard the cam gears if they are both held tight by the timing belt. Can someone please explain the proper procedures in doing this?
Thanks,

Oz, the outer ring is held by the timing belt. The inside of the cam gear spins either toward the firewall or away from it when the bolts holding it are loosened.
Cam gears are two parts. The outer part stays where it is, interlocking teeth with the timing belt. while the other, inner part, thats connected to the camshaft can be turned. Once you tighten the screws on the gears, the two parts become one.
Its really not complicated, if you could look at some cam gears actually on an engine, that would help.
whats the general rule of thumb for advancing and retarding? like if you advance you gain in the “x” powerband but lose in the “y” powerband. i kno the only way to really test it is to go to the track but i still need a lil insight

Thanks-a-bunch guys! I didn’t know about that coz’ I haven’t taken off my valve cover yet. But just looking at the pics, it seemed the outer ring was together with the inner ring.
First off to answer 2simplex’s question. I believe cam adjusting gives you more top-end. I don’t think it gives you any low or mid end power. If anything, it’ll be very slight compared to top-end power. Also, torque increase is very minimal compared to Hp increase (For example, if you get 5hp by cam timing, you’ll probably end up with only 2-3ft/lbs increase in torque). I could be wrong though.
Now, after all of this, I don’t see the reason for buying adjustable cam gears. The only advantage I can see (about adjustable cam gears) is that it has laser-etched degree marks for accuracy. Otherwise, if a stock cam gear can be adjusted then why bother with adjustable cam gears? Hmmmm…sounds like a good teg tip for me to research…muahahahahahahha:evil:

No, you cannot adjust stock cam gears because they are all one piece. All of those that replied were under the impression that you had aftermarket cam gears.

Acutally, the track won’t help you much because there are no engine measuring devices out there. Perhaps you meant to say dyno, which is the way you truly get acurate tuning from adjusting aftermarket cam gears.
well i think actually i think the track is better cuz ur taking that horsepower to the wheel and applying to a real world situation [the track] and with a timeslip i could test low-mid 0-60ft or the 1/8mth mile and mid-top of course the 1/4 mile…but i just want my cams adjusted that will net me quicker in the 1/4 mile.
