Finding Stall Speed

I have heard a couple of ways to find out where your converter is at but what is the best true way to find the stall speed....no the flash either :working:

You could probably just power brake or whatever, except instead of lifting the brake when the lights turn green, you lift off the accelerator when you get the reading.

Isn't that pretty much the whole idea of stall speed? Maybe your brakes aren't strong enough though... possibly adding handbrake to foot brake would help.

Yep, -
Drive the front of car against a wall (There could be options to a wall :clueless: ), hit the pedal, and see how many RPM you can get (Be sure the rear wheels don't turn)....   :burnout:

I'm pretty sure you just power brake the car and bring the revs up. When the car starts to move that's where your stall is. Just watch the tach and count out loud as you pass rpm marks, 2,000rpm, 2,100rpm, 2,200rpm and remember the last position the tach needle was at just before the car moves, that is your stall speed. Your stall speed will be the maximum RPM shown on the tach.  :2cents:

To get an accurate stall speed,you really need a manual VB so you can put it in third and floor it. You will get a higher stall in third gear than low because you are taking all the gear multiplication out of the drive train. A low gear stall will give you a close idea of what you got though. :2thumbs:

I heard of coasting the car as well and have it in drive and hit the gas pedal to the floorand watch it power up on the rpms and see where it grabs.. ??? "coast in high gear and stab the throttle test"...

I've tried this method before, but the car never moves. The tires just break loose. Am I holding the brakes too hard maybe? :dunno:

1. or drive - is not an issue,  you won't get it to shift up unless your wheels are turning...  :burnout:

With a manual VB no,with an automatic VB,yes. That is why I said you really need a manual VB to check it accurately.
