It does not work.
The spline lock has slipped and that was at a track.
Pinned hub is the only way.
PERIOD.

I completely understand as I first used the welding analogy. CBC won't stop anything.
Debate - Did the VTT "Spline Lock" Crank hub slip?
Customer car running spline lock spun hub and had to call it quits at a major racing event recently... How is that possible if the design was so strong it broke your test rig, as claimed in the original post?

One last thing... you already said that the Hub itself can still spin without that bolt losing torque...so once again...cbc does NOTHING....
It does in fact "capture" the bolt ...so when the hub spins, the bolt doesnt fly out and destroy your radiator or fan.
Happy now ?
This is well said. I don’t see a point of a cbc. Prime example with what happened to my friend the CBC would have done nothing. Or when @RuskiRacer’s hub slipped.
Ah....a radiator damage preventing device! See, it has some purpose.
Don’t worry with my luck the whole hub would fly into the rad
Haha, I was thinking the same thing, instead if throwing a bolt through the radiator, with cbc you can throw the whole hub through it for maximum dramatic effectDon’t worry with my luck the whole hub would fly into the rad
WIth your luck, your motor will scavenge, back suck some road debris in through the exhaust, wipe one of the turbo impellers, and all that stuff will chuff back through your exhaust valves and N54Destroyer the motor.Don’t worry with my luck the whole hub would fly into the rad
It hasn't already? Isn't this you....Don’t worry with my luck the whole hub would fly into the rad
Its at about 30 seconds or so
No you still are not grasping what the CBC is designed to do.
The CBC is designed to stop the bolt backing out and loosing tension on the hub which is the main issue, if you spin the hub whilst the
bolt is fully tensioned and locked that's a completely different issue and not what the CBC was designed to do.
You will need a redesigned hub of your choice to stop that from ever happening and has nothing to do with the CBC.
The bolt will never fly out as your motor will grenade itself before that ever happens even without a CBC
The problem is even with a pin lock hub or what ever the design you use the bolt can still back out and this is what the CBC will stop.
If you think the CBC is a waste off time why do you think BMW uses them on high RPM motors with DCT from factory.
Don't believe me look up the s65 motor on real oem.

I wish I had a picture of what mine looked like when it spun the hub. Just han
Lol marty your delusional. Pinning is the only real solution. How much is Tony paying you? The bolt can only back out if your harmonics inside your motor are so messed up or if you did not torque it properly in the first place. I had the vtt crankbolt cover bs its a waste of money it encapsulates the bolt and had nothing to do if the bolt will back out and the hub spins. The crank pulley comes off and the bolt backs out
This will never happen as the motor will shutdown and seize before this ever happens, this is the type of silly examples people use
to try and justify an ill informed argument.
You might think its funny but it shows the lack off knowledge some of you have with the comparisons you state.
Your delusional as even on one of the worlds smoothest motors like the s65 BMW's engineers decided the CBC is needed. WHY ?
I vote @fmorelli into the Associates if he wishes to join.
