Crank Balancer snapped off (Whipple 2.9)

The problem I have with crank supports is you lose your sway bar.

I have installed a crank support and also have lost the sway bar. But it is not a problem for me.

I have no issue without a sway bar. Car still handles better than 95% of the cars on the road. If you crash without a seat bar….it’s more than likely not the lack of sway bar that causes it

I have a 6 rib Whipple with a crank support and did not have to give up my sway bar. I'd love to have the 10 rib, but not willing to give up the sway bar just yet. I believe there is a member on here who has been 8's with the 6 rib so I still have some room to grow. I will say that after lowering the motor 1/2" a belt change is going to be a total PITA.

I was wondering if Ford approved the Roush SC , they must have run some harmonic tests with it. In this case there is some back door proof that a belt running a SC is possibly within acceptable Harmonic levels.
My question is, if the kinetic crank stud is a improvement, why wouldn’t they fit a similar fastner when doing a warranty approved Roush ? Could the kinetic change harmonics for the worst ?

I'm not sure that Ford actually warranties the Roush. I believe it may be Roush taking over the powertrain warranty responsibilities.

I believe both dampers are a bit heavier, and also move some of that extra weight further forward.
Every ATI/I.W damper I've tried since 2007, has been at least 6-10oz heavier over the stock dampers.

maybe I’m reading it wrong but this shows that they are lighter but don’t quote me. The hub adds 2.40lbs so ati should be 7.90lbs

Maybe a stupid question, but if the damper can be improved, why hasn’t Ford done so ? They have the skills, so a better domper wouldn’t cost more if it’s just a case of optimising it ?

Ford did exactly that in 2018, which upgraded from a traditional elastomeric to a viscous fluid-style damper. Note that the 2018 got a higher rpm limit and, anecdotally, you rarely hear of opg failures in a gen3. However, the cost of the damper increased by a factor of 2-3x. Unfortunately, it appears as though Ford switched back to elastomeric damper (and also got away from the forged timing gear I am told) for 2021+.

Innovators west, and save crank stud is your friend

I'd guess probably because everyone with a Gen3 is looking over their shoulder and desperately afraid of their warranty clause. Come 2023 we might find a rash of failures to equal Gen2 rates.

But you could easily be right. A viscous fluid self-balances to much tighter tolerances than machined and knocks the peaks down a bit.
