Other than the cool winding noise you get from installation, what is the major benifits and downfalls of installing cam gears??

 

Pros...

No chain stretch.

No chain break.

No chain slack.

Dead accurate valve timing through entire RPM range regardless if your on the throttle or not.

Cons...

Noise.

I've heard *don't have any direct experience* that the vibrations carried over from the crank to the cam can cause premature lifter/lobe wear, but could be an old wive's tale.

 

Another con:

you're out the decently hefty price for the gear set whereas a chain would be more than likely sufficient.

 

Yea. I was gonna mention that, but a "good" chain and a "cheap" gear set are pretty close in price.

But if you're comparing "good" to "good" then

Expect to spend 3-4 times as much.

 

gears are way more $25 for a dr chain, at least $125 for the cheap gears.

i have the dynagear drive set, very very whiny.

you can get most in both loud and quit sets, these didnt say when i got them. you can also find straight cut [90%] or helicut.

i wouldnt buy another set , but these should last 10 years anyway.



one thing i have been told is that they can screw with the knock sensor. i have notice at very low idles [500 rpm+/-] that you can hear a grumble from the gears.

i am doing a tpi swap and am not sure whats going to happen. i dont want to swap them out.
