i got some adjustable aem cam gears and was wondering what i should adjust the cam gear timing to to get the best cylinder scavenging, in turn best valve overlap/ i got a b20 intake manifold, intake, k&n... full exhaust header, and some other junk on my b20

 

Every engine is different. Dyno Tuning is your key for the adj cam gears.

SO you are running stock cams?

Do you know your cam's LSA?

You are not going to experience that much power gains from adjusting them just with the mods you have.

Do you know how to tighten the LSA?

Do you know the affects of adv. or ret. your cams? There is many different outcomes depending on how you adjust your gears.

For Example if you advance both intake and exhaust cams, it increases bottom end power while decreasing top end power, closes the exhaust valve earlier and opens intake sooner to move the whole overlap period earlier where it works to scavenge cylinder better at low rpm's.

 

Increasing overlap generally moves the torque curve up the rpm scale... decreasing it moves it down the rpm scale.

Get it on the dyno to make the most power where you want it. As a rule of thumb don't go past 6deg advance or retard unless you have clayed the motor.

 

i would like more power in the lower rpm range cause the set up now pulls hard higher rpm and doesnt stop pulling, i got some dynos at my school so i could prolly check that out but i was just wondering if anyone had a similar set up and what they did
