Truetrac Failure

[mumblezzz]

Yeah. Torsens don't wear out. They just break.

I slapped some burnouts on the back and dropped a skid, ah... i just dunno, sometimes it bites one, and others when it feels like it... 2 wheels.. well this is one of the days it decided to be nice to me.. http://www.youtube.com/watch?v=S3-AaXN2TZ0

Nah, its full gay, i'm over it, it still does 2 in line locks and straight lines etc. but once u load up one wheel a bit, its gone bak to 1. the gay thing is, it was wicked for a few weeks when i first got it, would never let me down, but now.. just this arvo i had 195 bald burnouts on the back, it was dry and got it spinnin in a lino as 2 wheels, then when i went to loop it, it bit the most hardcore 1 wheel ever,like it was an open again... i'm spewin, i mean burnouts r ok, but not being able to pop donut or drift... bit gay

Seriously, how old are you?

WTH?! Mighty impressive then, what were you doing? I've not hear of very many failures from a Torsen, and certainly not like that. I'd be willin' to bet that was a manufacturing defect..

[BigWorm]

The JZA70 torsens have also been known to fail, dunno if it's a Toyota thing but truetracs don't seem to suffer the same weakness.

I think norbie broke 4 w5x gboxes, and the true-trac was still going strong last I heard.

[JustCallMeOrlando]

Even when he let the oil run down ey Norbs?

[Norbie]

Yep, last outing at the drag strip it apparently spat all the oil out the breather, and the thing still didn't die. After all my drivetrain failures the TrueTrac has been the most reliable component, and it still lights up both wheels consistently. Well, it did last time I drove the car months ago.

Well isnt the whole reason behind a torsen lsd a safer lsd for (girls) sorry inexperienced drivers . they were never meant to work like a clutch pack lsd
Dave

yep

and the exact reason why they are a total and utter waste of money

down with truetrac!

[BigWorm]

What, so you missed blaze's post?

Torsen diffs outperforms any clutch based LSD on a road course, and there are no two ways about that. Clutch limited slips were a simple and economical method to have limited slip differentials, but are in the end not really great at any one thing. Great for an OEM limited slip for wet pavement and light duty, and mild performance. Torsen diffs are the best for race cars, and spools are best for drag cars while lockers are great for off-road vehicles.

Torsen diffs were created purely for performance, not for safety, not for noise, not for lack of clutches. Though those are coincidental benefits (except the safety thing, not sure how they would make anything safer)

The "safest" driveline would be a one wheel peel FWD car.

[MR 1JZ]

its written on the intahnet it must be true...

show me how many circuit cars run torsen diffs over mechanicals...drift/time attack/endurance/whatever...

[BigWorm]

Show me where it says they were made for safety?

I have no idea how many drift/time attack/enduro/whatever cars run torsens (except maybe drift, where it would all be weldies & hektik jap 2 ways bro, but that's a totally irrelevant application as the aim of a drift car is to break traction, whereas the opposite is true for any race car) but I can show you a thread full of people that have had great success with them, & not one of them is the kind I'd describe as having any kind of driveline sympathy.

meee? nooooo

What's wrong with the helical LSD in the front of your Evo? Or is yours povo spec with an open front diff?

[wilbo666]

Also clutch type LSDs don't break either...

Oh wait a second, here is one I prepared earlier, before my TruTrack...!



Trosen diffs have a place,
>Don't wear out (ok, everything mechanical wears out, but they don't wear at anywhere near the rate of a clutch type LSD)
>They work in a fashion that most people are happy with, sure they aren't THE best LSD for drifting, but lets be honest, in drifting the best LSD isn't an LSD, it is a locker. You want to limit the slip to zero (weld, spool, air locker, whatever...).

Also I'd like to see a youtube vid of it single wheeling? Might give us all an idea what is going on?
