+/-2 Degree timing sprocket

[gabbyduffy]

       Does anybody have a vender that can supply a 2 degree timing sprocket? All my searches came up with a 4 degree sprocket only?

don't think so....2 degrees gonna kill you ?

No, just want to try and get it as close as possible. A +2 degree advance sprocket would get me with in 1 degree of speck on the front cam and 1 degree where it should be on the rear cam.
                      A 4 degree advance would put me with in 1 degree on the front cam but the rear would be off 3 degrees. Not using a timing sprocket at all would put the front off 3 degrees and the rear only off 1.
                      I would like to know how much of a difference it would make in timing when the tensioners are under load from oil pressure but thats another topic totally. I copied a tool from the home made tool section and retested.

I think you can get 2* sprockets from TTS, Steve was showing them last year at Cinci. The main improvement was the tight fit on the crank, unlike the 1-2* slop fit of the stock gear. He said they would be producing 2* 4* & straight up.

I saw them at SEMA in November when I met with him on another matter. He was changing to a new manufacturer and monitoring the quality factor. The ones I saw and handled looked pretty good. If that has worked out in the past 4 months he should have them (or be close to it). You'd be able to adjust to what you want.  I don't see them on his web site yet.

One of you guys should Design a adj.gear like the one Clark Hemrick had,long before Bobby woods design $$$$$,and do some real world testing......

  TTS already has one for the late chain drive

[joe_lyons]

Tman does also

Just called TTS and they are not available yet, also called T-man and they don't sell any timing sprocket either according to the girl that answered the phone. Any other suggestions?

Is Hemrick Performance still around?  They had the first one I have seen.

What's the home made tool and how did you use it? I guess this should've been discussed in your other thread but shouldn't solid lifters be used to get accurate readings? Perhaps some sort of collar to hold the chain tensioner pistons at maximum travel? Does chain movement effect timing events in a running motor? Is it possible to have a fraction of a degree in difference in valve openings from one induction cycle to another?

he passed away. his son lost interest,

both events were sad, a product with a lot of potential that has been discussed here before,

[sfmichael]

saw one at Cinci...maybe at Woods booth - don't remember

A +2 degree advance sprocket would get me with in 1 degree of speck on the front cam and 1 degree where it should be on the rear cam.
                      A 4 degree advance would put me with in 1 degree on the front cam but the rear would be off 3 degrees. Not using a timing sprocket at all would put the front off 3 degrees and the rear only off 1.

I can see a +/- 2 degree sprocket would be useful for tweaking a cam
But in this case
your problem is that the cams were not in spec
why not go back to S&S and get them swapped ?

T man web site today Chain drive cam special with adjustable gear $395

Who's to say any are in speck? 3 guys on this forum all have the 1 cylinder cam off by 3 degrees or more. I would hate to go threw all the hassle and end up with another chain drive cam off speck. I bet guys rarely degree the cams they install, this is the first set I ever bothered to do. I'm guessing the cams are off speck more often then not.

I bet the cams are closer and most are right on, the crank gear having slop is going to provide variance
Plus chain stretch / tensioner not pumped up, all variations

How much of a difference do you think the Tensioners not being pumped up makes? I'm thinking oil pressure could make a lot of difference. My rear cam is a whole lot closer then my front cam which got me thinking about the difference the tensioners could make?
