you're a retard... plenty of people on this board know my car. search my name... and yes sorry bud but your "Katech chain" is an LS2 chain. now you're calling your wonderful "Katech chain" a **** chain. i use it because it works and it was all you could get that was good when the motor went together 3 years ago.
so do you have an ls2 chain in you motor or katech ?

The C5-R chain is used in almost everything we build. Solid roller and hydraulic. It's also the C6.R chain. It's been through:
10 hours of Petit Le Mans (ALMS)
12 hours of Sebring (ALMS)
24 hours of Le Mans
24 hours of Spa (FIA GT)
24 hours of Daytona (Grand-Am)
24 hours of Zolder (Belcar series)
30 hours of Circuit de la Sarthe simulation durability on the engine dyno
10,000km of the Dakar rally
Baja 1000
All the 24 hour engines are solid roller engines. We've also used this on 1000hp twin turbo LS7s. Horsepower doesn't really break timing chains. It's usually harmonics. I'd be willing to be the guy that broke two has a solid crank pulley and not an ATI damper.
People buy double roller chains because they think they need it. If one is good then two must be better, right? Same reason why people buy heavy roller rocker arm kits when stock ones work fine. (We've never failed a stock rocker arm either). Then they need a big heavy spring to control the big heavy valvetrain combination they have. Big heavy pushrods too. Then they need some aftermarket lifters because the stock ones can't handle the spring pressure. After that they start breaking timing chains. Time for a dual roller timing chain. We often see valvetrain systems as a mess. That's why Katech invented the Optron valvetrain dynamics cell which was later copied to become the spintron. Our endurance racing success has a lot to do with that test cell. Anybody can make horsepower, but when you start building valvetrain systems that can stay in control, you start winning 24 hour races.

The Katech chain is not an LS2 chain. It is the IWIS race chain.
Over 1000 C5-R chains sold and never broken one at Katech or to my knowledge any of our customers. There was one car that was shipped overseas on a boat in gear. The rocking back and forth ended up failing the chain. This is the only one I know of that ever broke, and that was due to negligence, not the product itself. This guy breaks two. I'd say there is something else going on.

Another broken timing chain (not C5-R) - another ASP underdrive pulley

Another ASP/timing chain failure

I'm beginning to see a trend with the ASP underdrive pulley.
