Is there a rough answer, based on HP or ET or 60-foot, as to when aftermarket axles are needed?
My car currently has a newer Eaton Posi with factory axles. Car makes about 400 RWHP according to the drag calculators, runs 11.8@114-115 with a 1.63 60-foot.
It's about to get a bump in power this Spring and should run into the low 11s (high-mid 10s once I address the heads & cam) so I'm wondering when an axle upgrade might be warranted.
Also, when axles do break, is it the axle just breaking from torque twist or is it weakening clutches in the diff that allow the axle to move outward and then break??
In the Pontiac G8s, the root cause was the latter and we knew the exact recipe (tire, converter, etc.) for when this axle ejection would occur.
