...and 2 out of 3 failures were NOT the stock chain? Interesting.

Re: Broken Timing Chain Poll In addition to knowing how many chains have broken, I would think you would need to know how many have changed a chain (possibly because of a H/C project), the breakout of which chains were used (e.g., stocker vs. Brand X), the reason the chain was changed, the mod list, and the resulting HP & tourque. Knowing how many chains have broken wihtout knowing anything about the potential population will not allow any meaningful conclusion to be drawn.

Re: Broken Timing Chain Poll I think you're dealing with minutia. I think those that changed chains for H/C projects will be well represented in this poll. The majority of the manufacturers I'm aware of are represented.
As far as HP/Torque levels at the time of failure are concerned, I'm not terribly interested in muddying the results with the extra complexity. The purpose of the poll isn't to determine the reason the chain was changed, only to identify the manufacturer of those that have failed. We can't drill down that deep until we first identify the failures. Once that data is collected, it can be evaluated and theorized from there.

Re: Broken Timing Chain Poll
Isn't the (i) SLP double chain and the (ii) RollMaster double chain the same unit?

Re: Broken Timing Chain Poll I'm surprised at the Rollmaster double breakage problem; i have one and it looked bullet-proof when I installed it a few months ago.... nice and cheap too!
I suppose we should do a separate poll to see if the broken Rollmaster doubles included the torrington bearings.....

Re: Broken Timing Chain Poll I appreciate what you guys are trying to calculate with this data, but my real reason behind this poll was only to identify common failures, regardless of manufacturer.
Everyone is too caught up in this timing chain debate, and I was interested in showing that no matter what set you install, you're not untouchable.

Re: Broken Timing Chain Poll ..the results are somewhat missleading since there is no corresponding information about the number of Rollmaster doubles or other brand chains included in the survey...
I assume the Rollmaster double constitutes the vast majority of replacement chains since it is preceived as a quality piece and sells at a very affordable price...
