I'm trying to do some research and think I have
a method for finding what your torque converter
is stalling at from a 1/4-mile ALDL scan.

If anyone has ALDL data from their 1/4-mile
runs and have a good idea what their converter
stall should be, I was hoping you could post
your results to see if the data supports the
hypothesis?

I need:
1) RPM reading when your VSS (speed)
first goes non-zero at the launch
2) What your converter stall should be
3) What kind of VSS your car has (or what
year car if the VSS is original) The
VSS should be magnetic in '90-'92
cars, and mechanical in the '82-'89
cars..

What I think will show is that the RPM of the
magnetic VSS cars will be exactly at the non-zero
VSS point. On mechanical VSS cars, the
stall will be 400-500 rpms less than the
non-zero VSS point...

Thanks for any help..

you can find the stall speed by holding the brake and gas and the stall will be the rpm the car either has to move or die.

 

Do you think?

This is only true if you have a trans brake...

 

You dont need a trans brake but you have to keep the output shaft from spinning so good brakes are a must.

 

Ok, anyone WITHOUT a transbrake
OR super-brakes, have any data
they'd like to share with the real-world...

 

ahh there's a little bit more to it than that man.

brakes, tires

are we talking foot brake stall, flash stall, true stall?

there's to many variables to be summed in, hold the brake down, push the gas and see what happens, and the car shouldn't die just because you are tourqe braking it, if it does, you have other problems.
