Truetrac Failure

[22abcdre]

Hey, I got a 1G rona and don't mind the odd skid when its required, so bolted in a truetrac to the IRS F series, worked good for about the first month... now it just acts like a really weak lsd, it'll barely pull 2 wheel donuts in the wet anymore... i don't know what's goin on but my truetrac just couldn't take the punishment and wore out real quick... has anyone else had a bad experience with the ol' truetrac?

[cambelt]

Maybe one tyre is balder than the other causing a loss of torque sensing of the lsd when wet . does it work in the dry

The TrueTrac is a helical-type mechanical LSD, it has no wear components. I've never heard of one losing LSD function? Mine has copped a lot more punishment than yours over the last 5 years and it still works great.

there only a 60% locker aparenntly..... thats what i was told AFTER BUYING it.... ive had trouble with mine single spinning ALOT,

tarmac motorkhana's are the worst, inside wheel goes nuts,

i dont recomend them,

[oldcorollas]

the inside wheel needs even a small amount of load to able to activate the LSD function

if you are lifting the inside wheel in motorhkana, of course the LSD won't function heh heh

as for doing helis in the wet.. err...again, if there is no traction at all for one tyre, then LSD function decreases...

see.. the Torsen is designed for driving... ie, when you are driving the car fast around a track/road, then it works fine.

if you are doing doughnuts, or hard turns and lifting wheels (due to poor suspension setup), then it doesn7t work as intended as it is not being driven as intended


heli boy, does it work as intended when you are driving hard (but normally) in the dry?

[blaze86vic]

Yeah, it requires both wheels to be on the ground. And I have noticed with mine that it seems to work better if you apply the power faster. I can drive in a circle and roll slowly on the throttle and it'll spin just the inside wheel, but if I roll on faster it'll break em' loose.

This is in my Vic BTW, not the Celica.

torsen is a multiplier diff, the wheel with less traction sends x times of torque to the wheel with more traction but when its free wheeling x times 0 torque is 0.

I can also confirm that mine does great skids...!

This is the first I've heard of someone having issues!

TrueTrac working!

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

[rob]

do you change the oil at regular intervals between your hardcore wicked burnouts?

[oldcorollas]

surely for your burnout comps, a full spool or CIG locker would be better?

please tell me you are not doing this on public roads

[IN 05 NT]

it lock up if you lauch it in a straight line, but once it does get light (ie trowing it around a witches hat) it singles, when you want it locked tight

i also had a bit of trouble at wakefield with single spinnin, but i will say, the last time i raced it, it had rather shit susp, (not doubting that!)

theres a brand called LOCKRITE, ive ONLY heard good thing's about them from people in my club that use them, tho they are a few hundread more,

i knew i shoulda just done another CIG

[oldcorollas]

yah, clipping curves and lifting rear wheel wil not help... but that is all part of playing with suspension setups

are lockrite the clunkers? (looks like it.. dog teeth lookin thing)
ie, there is no LSD action when not accelerating... as soon as you accelerate, it is 100% locked cos of the dog style teeth...

if you realyl want a welded centre or spool, but also want to be able to legally drive aroudn the streets.. lockrite is great..
if you want progessive LSd action to go around corners... not so good..


or is it the one that disengages the outside wheel, providing all force to the inside wheel (or is that a detroit?).. that one would be bad for.. most things

what you could do, to make the truetrak more effective.. is to drag the brakes or handbrake when you are leaving the corner... that way, you are applying more force to the inside wheel, and thus transferring mor epower to the outside wheel

[mumblezzz]

I tried that with my jzx100 torsen and it doesent work. Plus you can't predict when its going to spin 2 or blaze up 1 wheel of glory.
I just forked out for a Tomei clutch type 2-way. Problem solved.
