did a burnout, car doesnt seem to like it

[Stegs]

80w-90 valvoline is fine with the limited slip friction modifier added.

They only difference to the differential between turning left and right is which way the differential gears spin and which way the suregrip clutch plates move. If the gears where worn and binding in one direction or the clutch plates were galled and only stick in one direction it might cause what you describe.   

Start simple .Drain the lube if it's that old look for metal in the lube or water after sitting.  If OK, install fresh lube + suregrip additive and test drive. Do some figure 8's in a parking lot.

yep, I didn't get a chance to do It this weekend, to many projects and a wedding.....

ill report back

You guys apply the brakes initiating a burnout?  How does that work and what does it do to the brakes?

Speaking for myself, I never do that.  That's what I identify as a brake-stand, which seems to be regularly confused for a burnout.  A brake-stand will bring the RPM up past a converter's stall, at which point engine torque will overcome the rear brakes.   The front brakes can usually anchor the car long enough for the rear to lose traction and create a smoke show.  In a drag race, you can also use the brakes to bring the RPM up against the converter for more stall at launch.

Personally, I don't care for brake-stands.  Seeing (or doing) a long, throttle-only burnout is more fun/impressive to me.  But brake-stands seem to be all the rage these days.  

You gotta love a 4 speed for that :
2nd gear, mash the throttle, dump the clutch

No doubt.  Though some autos will still fry the hides deep into second gear.

If there is enough engine power the auto trans will shift through the gears automatically and continue to fry the tires through third gear. Well built big blocks can do this. That is the big smoke show. My small block doesnt make that kind of power. I put my auto trans in second gear, then hold the brake and mash the gas, once the tires are spinning in first gear I let go of the brake, it will shift to second at 4500 RPM and fry the tires in second until the car picks up enough speed that they grip and go. Others may have to put the trans in first to keep it from shifting to second and do the burn out that way if the engine is not strong enough to smoke the tires in second.

You could put the trans in first and do a standing burn out, brake stand or whatever you want to call it. The engine has to spin the tires with the rear brakes applied trying to hold the wheels still. It takes a lot of power to shift to second while trying to drive through the rear brakes and keep spinning the tires doing a standing burn out. Again a well built big block can do this.

Standing burn outs are easily done with the help of a "line lock", or "roll control" system. It applies the front brakes only, allowing the rear brakes to release and let the tires spin more easily. It was originaly used on manual trans cars at the drag strip. The line lock can be set, the front brakes are holding the car still with the rear brakes released, the driver can then operate the clutch and gas with both feet while the front brakes are still applied.

That's burnout 101.
