ok guys, ive broke to rears so far and lets face it im getting tried of it. i want to stick with a c5 diff! i already have 300m OP shafts, carbon clutchs, c6 side gears, i have DTE's diff/trans brace aswell. Tonight i split the case. My question is what are my options? Also does some one make a diff cooler kit or have a write up on it? and is there a stronger case then 3 rib? remember im NOT going to a c6 diff

 

Questions for you so I or anyone can help

1) how much RWHP / RWTQ

2) What does your Torque Tube look like

3) where are you breaking case at

4) how are your mounts

5) DTC diff brace is it over torqued

6) what gear ratio do you have

7) have you talked to Rick @ RKT (forum vendor)

7.5) have you talked to Jeremy @ RPM (forum vendor)

8) What are you doing when breaking diff. i.e. drag racing street driving

I am asking these questions to you as I dont have enough info to help you out. I have a friend putting over 700 RWHP to a RKT slightly modded C5 Diff. He has not had any issues yet 10k miles so far.

He's asking the right questions!! Answer these and we should be able to help you out!

 

1) how much RWHP / RWTQ
401rwhp/373 tq
2) What does your Torque Tube look like
not sure will hopefully get a clear look at it when i start pulling the rear. what should i look for
3) where are you breaking case at
the rear and around the driver side op shaft. ill get a better look hopefully today
4) how are your mounts
stock as far as i know, what do they need to look like? im new to the vette world.
5) DTC diff brace is it over torqued
i hope not, a shop did everything the spec's(what they told me)
6) what gear ratio do you have
4.10's which ill prolly swap out

7) have you talked to Rick @ RKT (forum vendor)
not yet happend last night
7.5) have you talked to Jeremy @ RPM (forum vendor)
same as above, lol
8) What are you doing when breaking diff. i.e. drag racing street driving
drag strip, i dont make it to the 60ft. Im a camaro guy, and i normally have a solid rearend so i no my driving style needs to change. but im tryin to leave the line at 3500




answered like this so i didnt miss anything.

also can i get a auto case? i seen a few on ebay, for a decent price. but i dont want to buy then it not work.

keep the info coming guys, and thanks again so far

 

What kind of tire are you on? A soft sidewall can make a huge difference. Wheel hop is deadly. Something like a CCW drag pack setup may do more for reliability than a bunch of hard parts.

 

Is the car wheel hopping? Did the shop you mention do both diff setups for you (that broke?)

It doesnt sound to me (and I may be wrong) like you're making enough power to grenade 2 well put together setups, without either wheel hopping the **** out of the car or dead hooking at high rpm's

 

That's what I was thinking too.

 

i have a ccw drag pack with mt streets radials, the car really dont wheel hop at all. i broke the first one(stock) a week after i had the car, and we did all the upgrades i could. and now i blew the case apart. i was under the car today and took a few pics. ill post in a min

heres a link to the rearend pics

 

Radials not (bias-ply) Streets? Those are still relatively stiff sidewalls.

Haven't seen pics yet. Assuming they'll show pretty typical damage.

 

pics are on that link, did it not work?

and yes i have the stiff ones. im going to go to a hoosier QTP i had them on my camaro.

 

One more how many miles on the stock diff when you lost it and did they use the same diff case. If they did ouch what may have happened is you blew up the gears in the stock diff. rebuilt it with stronger stuff and your org. case was cracked and it blew out.

As for my car I have 465RWHP 450RWTQ With a upgraded by RPM diff with 3.42 gears and run in the mid 11's 125mph on street tires should do better with DR will see here in a few weeks I have the DTE Style brace and was told to just snug it not tighten it to the hilt as it will but un-due stress on it. I will go look at your pictures and get back to you tomorrow

Can see links to pics, but not authorized to view. Nice sig pic there.

 

opt'ed in

 

i had the same thought, i figured once it blew the first time i put a hair line crack some where in the case. the case had 48xxx miles on it. im going to try and call dte,rpm, and some other places just to see it they have a good case.

 

Finally saw your pics. Not that it'll make you feel any better:

I know you said you don't want to go the C6 route, but... Other options include A4 and soft tire.

Oh yeah, LG does offer a diff cooler. It's a nice setup but heat isn't your problem here.
