Cv prep already?

what’s up guys! We have an Idaho Dunes trip coming up next month so I figured I’d get started on the prep (after pulling the back up ls2 out and putting the fresh 418” ls3 back in with new turbos and some other goodies)

But anyways, cv stars have some minor and some pretty bad pitting. Two of them have two seasons on them and two have one season, one star is still in good shape. Just wanted to get some opinions on the cause of this pitting…

Axles are strapped at 24 degrees

Cv’s were prepped pre season with certified premalube black Xtreme grease (the stuff that Alper recommends)

Cv’s are empi 934’s from Kartek, I believe they’re the stage two chromoly ones.

First season on them was running a twin turbo 418” ls3 that made just shy of 800whp on low boost. Second season was one trip on the big motor, lost oil pressure so I pulled it to rebuild and swapped in a stock stroke ls2 (rod and piston motor, ported heads big cam etc, with the twins installed, 600-800hp playing with the boost levels all season from 5-15psi)

New motor is making about 780 on 7psi, 1150 on 15 but I likely won’t turn it up that high, car weighs 2800lbs

So, are they just cheap china cv’s, not enough grease or not quality enough grease, to much angle, to much power for the cheap cv’s?

Of course I know they’re bottom of the barrel cv’s but they’re holding up pretty well so far and I know many people swear by the empi’s for 934’s

Thoughts?

pittings is where the metal gets so hot it can stick to the CV,
If you broke the CV, I would say you need a stronger CV, with pitting, it needs better grease, or grease them more often, or angle is over limit,

I always thought the pitting was from shock load but that makes sense! I’ll likely just replace the stars for now and maybe upgrade to some higher quality cv’s later.
