Anyone using a gear drive instead of a timing chain?

Wow, that's interesting cause I found one made in Australia for like $500 and it looked real good. I wonder if they know about the knock sensor thing lol. I'm not going to be the first one to try it out though so I guess I'll just stick with the chain.
Thanks.
Thanks.

You know, I tried searching as soon as I posted and now I can't find them. I was going to post a link, they were on ebay but the auction ended and for some reason I deleted them from my watch list. They will probably get relisted because they are from a shop in Australia and are brand new, I think they custom make them. I'll keep an eye out for a relisting.

I've been looking at using one. Diecrest here in Australia makes one. It's a single idler design with the idler gear fixed to the block. They reckon they are virtually silent with everything running on ball races or torrington bearings.
The problem with the old Pete Jackson dual idler gear drives is that they just relied on the bracket holding the two gears together to keep everything in place. force from the crank gear actually puches the two idler gears into the cam gear and forces the cam up as well. This means the gears aren't meshing together nicely and hence the noise. The single idler design is much better with the crank, idler and cam gears all fixed in position in relation to each other so the gear lash is correct.
At just over $400 they are a bit more than a good chain setup.

I don't think there's much advantage to one other than being able to quickly advance or retard the cam if you also had a 2 piece timing cover.
The chain setups these days are very good. I just thought it'd be neat to try one as I was changing the cam anyway.

Do you know anyone running this setup? Does it mess up the knock sensors?
