Why do ya think your dif went? It certainly wasn't from the hop. Weak r&p? or did the case flex and crack?
the case and internals grenaded, the ring gear was in several pieces and the diff housing is unrecognizable it was in so many pieces. But once again there was no hop at all what so ever.......the getrag junk diff just wont support the power with the V being so heavy.
how much power do you have n20junky? I just don't see how it grenades like that without something improperly installed or aligned unless your hooking hard as hell... I beat the living hell out of my car and i just spin everywhere I go.. I bang gears off rev limiter and dump the clutch all the time.. I am on a stock differential. I just don't get how you have went through so many if your not hopping anymore. Hopping will destroy your rear in no time, but if your not hopping how does it just break? Wouldn't your weak link be tires if everything else was installed right?.. With good traction you will find your weak link in a hurry but do you really hook that well?
Without hop things just wont break and shatter like that unless you are HOOKING HARD... I have Never broken any rear end stuff unless I was running wrinkle wall slicks on my cars.. Here is my 67 camaro.. I spin like hell in it.. this is what happened after my 2nd launch with ET drag slicks pulling 1.5 60 foots...
By no means I am trying to call you a liar or look down on you anything like that.. I just am really really curious how you keep breaking your rear if your not hopping.. If your not hooking and just spinning everywhere I just don't understand how it could break. Yes our cars are heavy but mine has never broken yet and I don't ever imagine it breaking if I am not hooking hard out of the hole. What were you doing when yours broke? please explain the whole story to us.. I am very interested in your setup.. I want to try to brain storm on my own and figure out how this is happening to you.
I choose to make my caddy not hook though, and if i really want to get on it and race it I can do a very good job and grip quite well on street tires which is all I can ask for... I don't run drag radials or et streets on it for a reason.. Because when you hook you find weak links really really fast.. I would rather spin all year long in my caddy than break once.. Plus doing a burn out in a caddy is cool as hell anyways.. lol.. anyways.. Please tell me more about your car and your setup.. I am really curious.
n20 junky if you can go into more detail on it and what happened and how it happened i can forward this to the getrag engineer to take a look at it.... i cant promise anything but i know they do read these things.
Neither Getrag or GM are worried about the differential design in an obsolete car that's no longer being built. Sounds harsh, but it's true.
I cant speak for GM but both auto companies i have worked for and now at do make revisions to parts on old cars. plus what can it hurt. the getrag guy i work with is a v fan...
It would be cool if you're right, but several years ago a few forum members (I believe heavy was involved) tried contacting Getrag about the steel version of our rear diff that they make. Getrag claimed it didn't exist, even though we have pictures of it. After being shown the pictures, they replied "Not interested".
lets see.... if you can come up with something on that steel diff maybe i can weasel a part number or something. was it to ask about them selling u a steel diff or just making a steel one for us?
either way its easy to ask someone a question when you are co-workers as opposed to an outsider.
Perhaps hopping from time to time off the track added up and created a crack? When mine went it was right after pushing the clutch in to go to 2nd and i wasn't going fast. No hoping, at the time at least, so who knows how many little hops added up. Perhaps if you never hopped at all (ie: put the DSS axles on the day you bought it) it'd be fine?
Also N2O, were you spraying in 1st?
still no info from n2o?
this is like when he did the axles at first and people waited like weeks for some further info. if no info is going to follow then why even post the pics?
