Thousands of cars have racked up millions of miles with very similar adjustable gears. I've never heard of anyone having any problems with one.BurnsSide42 said:well - adjustable cam gears sounds neat and all - but I would not pay $170 for a pair... not because I'm poor - and not because I'm a tight ass - but merely the fact that I don't trust those. Think about it - what's keeping one of those lil bolts from backing out... and well - jumping the chain and f-ing up the motor. Seems like It needs some more investigations preformed before anyone jumps at those. :roll: Just my $0.02
Yea i may give them a shot once I get some 2.3L cams and my ECU. Should help to put the power right where i need it...more on the low end off the start. Hopefully if tweeked correctly, I can launch at a correct RPM without getting wheel spin or bogging down.Tweek's Turbos said:I think I will give them a shot. As long as they are tightend properly, it should be fine. Plus its not hard to open the cover and check them once in a while.
Seriously, thousands of people have been using this sort of gear for a long time. I've never seen one fail - IMHO, it's no more risky than any of the other mods that people do.mike saunders said:Gotta go with Burns on this one, DriverFound. The article I linked to diplomatically mentions multiple cases of gear slippage "with catastrophic results" because users weren't torquing the inset hex bolts tightly. AEM changed the Allen heads to standard hex heads to enable users to apply enough torque....
How else are you going to adjust valve timing? Specifically, adjust it independantly for each cam? Sure, you can adjust ignition timing all day long, but I can't think of any other way to adjust valve timing. Unless you're going to put the timing chain/belt on a tooth off or something, but that's going to be a HUGE adjustment, not the fine-tuning you get with this.I don't get what the difference between buying those and just playing with the timing?
I see what you are saying here, but what's the benefit of being able to tweak... say your exhaust cam so it's a touch off from the intake cam?How else are you going to adjust valve timing?

IMHO it's more of a correction device than a power-adder. Many times, upgrades we do provide benefit in a certain rpm range - cams, exhaust, etc up top, etc. Being able to fine-tune cam timing can help you put that power where you want it, instead of where it'll happen on it's own.DeLorean said:I see what you are saying here, but what's the benefit of being able to tweak...
