--ESP OFF-- is trouble
This is what I'm afraid of. My car seems especially ESP-handicapped. Can you get a decent burnout now with ESP off, or is it no different for you? Obviously any increased traction on launch and throttling out of corners is welcomed but I am also looking for a fix for burnouts when I am at the strip. Sick 1 second of spin then literal closing of throttle.
Who did your install? I know this has an affect on performance.
I have never went to the track with drag radials to where I need to get a real good long burnout to heat them up. On my street tires though I just turn esp off, do the power brake and as soon as I feel the car start to cut power I let off the brake and stay in the throttle burning them up toward the line with the car in M1 then hit the brakes at the last second.
This is what I do

The diff was installed near Atlanta, GA at a shop called Malones Performance.

I have had my quaife for about 5 years now. Esp is still cutting in. What I do notice is the quife keeping me straighter when I do lose traction or have traction issues. Knowing what I know now, I still believe the quife sholud be in the top 3 first mods to do or in conjuntion with other mods.
i thought it only needed shims if the backlash was out of spec,and if that was the any unit you buy would need to be shimmed?
just trying to understand.
Dyno mode is scary..this is coming from someone who use to spend 6 hours every friday/saturday at the track drag racing and also went thru a drifting/powersliding phase. This car needs a LSD more than any other car ive been in.
I still dont understand why it was never given a LSD...516tq and 265 tires...just doesnt add up haha.
100% incorrect. Maybe if you understood how the system worked instead of thinking you do, your posts would actually help the form instead of confusing it. Try posting that on the other forum that all of you newbie guys went to before you realized that it was a forum for FOOLS!!
Here is how it works David: The ESP system monitors wheel speed through sensors in the hub so when you install a LSD the wheels will be more likely to stay within the percentage of wheel speed difference that is increased when you "shut it off." All that does is increase the amount of wheel speed difference allowable before the ESP kick in.
This is how you do a burnout and this car has a Quaife ATB LSD installed by TTM. Try watching it and learning from it. This car has Hoosiers too and I didn't have a problem doing a burnout!

The car will instantly activate ESP if you push the throttle halfway down from a stop must less all the way down. The car will instantly activate ESP if you run 40mph and mash the throttle causing a downshift. A LSD will not come even close to remedying the computer cutting power. Again, I don't know what you drive but I drive an E55 with a Quaife LSD EVERYDAY (when not working out of town) and know exactly what the car does lmao 
While you may know a thing or two don't try and belittle me like I am some idiot, I have been around a while and have been modding cars for long enough not to be a "newbie guy." And when I say modding cars, I mean with my own two hands tearing down/building an engine or what have you, not writing checks.
Congratulations, you drove some guys car you worked on doing a burnout in either dyno mode or it is one of the ones that will allow you to do a burnout not being in dyno mode. That is a widely known fact that some E55s can do this while others can't. But you are giving this credit to a LSD, really?
My car with a Quaife LSD, see the two tracks?


And see the ESP light go to town. Hell it was flashing all the way to 80mph on the last run in the video and no I didn't have bald tires either, those street tires were able to do a 1.82 60ft. So much for that magical LSD ha?
I must have a defective one?

ESP doesn't just compare wheel speeds across the axle (That part you were correct on) BUT it also looks at the Delta of Front vs Rear wheel speeds AND it looks at the accelerometers in the car to see if the car is in a turn which it also correlates with the steering angle sensor. If there is any lateral G on the car that transitions the ESP computer to another lookup table.
Dyno mode ignores those inputs which is why it's popular for drag racing
looks like the Quaife's have come way down in price too,i've seen them as low as $900,where the Wavetrac seems to be $1095 everyhwere.

you're a real piece of work.......




I tried launching without ESP at the recent VMAX day and got the car almost doing a 180 in no time. The quaife can be tricky as the progression from 0 - 100% lock is not that smooth as some clamp / spring type LSD's are .. progression much harder to "feel".
Anyhow I would be much more carefull lauching / driving the car without ESP... and never really have until this one time - basically from the experience I got at the skid pan. In the wet there is zero advantage. YMMV in the dry ... I for one won't use it again unless the conditions are ideal.
