Default Cam gear settings

whats up guys. as some of you know, my friend recently obtained yooly's old car. when he go it though, the intake cam was retarded 10*( ) and the exhaust cam was at 0*. so he reset the intake back to zero to get the car running good.

my question: what is a good setting to move the torque curve slightly lower? i know you really cant get more power from adjusting cams, but a lower torque curve will let him save some gas.

they weren't measuring power. on all 95(obd I) an older cars they have to put them on a dyno and measure emissions with engine load.

Did the cam gear slip a tooth on the belt? 10 degrees is A LOT of retard. Best way to tune the gears is on a dyno, every car is different and reacts differently to cam gear settings.

if so, this would prolly be the case, but still weird.

i was there when my tech installed the gears...saw them torqued to spec and all.

but then again, they are AEM gears.

the engine is equipped with AEM cam gears. and it had slipped or something to 10 degrees of retard.

but i dont know if AEM cam gears are that bad. Stephan Papmeister has them on his drag civic, which put alot more stress on them than this engine.

I've heard of a lot of problems with the gear itself slipping from only having 3 bolts, but the timing belt itself can also slip on the outside of the gear, one tooth is about 10 degrees if I'm not mistaken. I would be willing to bet that Stephan has a set of custom gears for his drag civic, and they aren't the off the shelf gears...I could be mistaken though.
