Default Axle Strength: approximate (W)HP level for 90 STD(HF) HB axles?

Anyone know an approximate HP/TQ level (max) that can be maintained reliably with street tires (maybe even 100 treadwear autox tires)?

I am going to say around 250-300hp maybe?

Yes, standard axles, are they actually hollow vs solid (dx,si) or do they just have smaller splined sections and a lower spline count?

I had a pair of std axles on my old std civic with a sohc zc. They only lasted a month. I drove on them pretty hard. They were from autozone. They were fine the first couple weeks but both started clicking bad after that.

A hollow tube can handle more stress than a solid bar of the same OD - I know it sounds counter intuitive, but that's statics for you. I've often wondered that since this is true, we don't see more companies using hollow axles. There's got to be something i am not thinking of...

BUT - the splines are also smaller on the outboard CV joint, AND I'm not sure if the CV joints are of different dimensions - these could contribute to the axles being weaker.

well first to second can be pretty rough on an axle as well...

to the OP:

a lot of guys on here just do the autozone thing with lifetime warranty.

you can get better of course. depends on whats important to you. its obviously cheaper but more of a hassle to use the autozones in the event that they go on you.
