8.8 guys come in
#23
This is getting a bit weird.
What BEFORE and AFTER information are you looking for?
Most guys stay with the same gear ratio as stock when switching to a better diff so there won't be any performance change from that aspect.
Most guys also don't run the OEM diff until it blows up either. It's more than well know that they don't hold up to launching from a dead stop.
If you are looking for someone that fragmented a gen 4 oem diff, then replaced it with an 8.8, with no other mods to the car and the diff is holding up to the same level of abuse that killed the gen 4....before you are convinced, that will be tricky.
Maybe we should all hear about the monster of a car that you must have if you need to be proven to that an 8.8 will hold up for your application.

You shouldn't need to be convinced to go to the 8.8 if the funds allow it. It has proven that it can handle the abuse a near 4000 pound car puts to the rear end over and over again. Sure, the OEM diff may hold for a while, but be sure to knock on wood after saying that.
It will be my next mod, and would have come before the built motor but one bit the dust before the other.

My point smart *** was that there was only 1 8.8 post in that whole thread but have heard tons of people doing the mod.
I didn't think it was a problem to ask people what the actual, measurable gains were on their 4500 dollar investment.
To me, no posted times = not a real improvement.

All I was really looking for was some 60' times with the new rear.....I am not spending 4500 to get rid of a clunk

Your answer will come when you ask yourself what your gonna do or plan on doing to the car. If you keep it stock and never do any clutch dumps or hard 1-2 shifts, then don't spend the money. But if you plan on modding the car, and/or driving it hard or go any kind of distance and take it down the track and do hard launching and pounding through the gears, you will eventually need to upgrade to the 8.8. Will your 60' times decrease? Probably, because you have the confidence that your not gonna hurt anything and you launch harder and shift faster, but its not because the 8.8 made it faster.

I understand the rear does not actually make the car go faster.
My point was that the stock v rear does not allow for a decent 60 because everyone is afraid to break it. So after spending almost 5k, I figured people would slap on some drs and hit the track and see what their performance car could do now that they got rid of the week link but I guess I was wrong.

Your not wrong. I wouldn't dare go the track without the 8.8. My times aren't worth mentioning because I wheel hopped both times very badly, and the computer cut power for a few seconds both times. Which, btw, would have destroyed the factory diff. Here is a video of hard launch. I believe this is a members car on here. Trying doing this with a stock diff.

Rayda I have a solution for you buy the best drag radials you can find, run your car down the track a few times if you can get a better 60' time then 1.9 then dont get the 8.8 but if your rear doesnt hold send me the drag raidials and im pretty sure I can get down to 1.8 60ft

Dragging a car with an IRS is kind of a moot point. 90% of all rwd cars that are cutting ridiculous 60s are running a solid axle. The point most in here are making is, its tougher. Is it more than a factory diff??? Of course. But, that said, its miles better. Whether it hops or not makes little difference, you're not going to kill it, even throwing down all the power that the chassis will handle. And that is the big point. I'm on the original 04 diff in mine. And so far so good, knock on wood. But I am going to be getting an 8.8 as soon as money allows. The 1/4 near my house just opened back up again after a few years being closed, and I'll be damned if I'm going to break a diff at the track and ruins everyone's night with an oil slick at the tree.
#38
Sure it does....being able to use the power you already have more efficiently will make the car faster.
After an LS7 clutch, the 8.8 will be the first thing I do to the drivetrain in this car. Why anyone would do engine mods before doing this is beyond me.

In stock trim they wont pull a good 60' because of bushings and rear end but weight shouldn't be a issue. Look at the v2s there running damn good 60' and weigh well over 2 tons haha

I bought the 8.8 so when I do dump the clutch and the rear wheels go hop,hop,hop I'm not waiting for AAA and a flat bed. Plus I took care of three issues at once. Weak Diff,weak axles and non rebuildable(at that time) drive shaft. I paid for piece of mind which to me is worth every penny.
Also, If I wanted a hot rod I would not have purchased a V. These cars are heavy with squishy rubber bushings on every corner.
