DynoJet
 

To me the most definitive way of checking the stall speed of a convertor is to run the car on a DynoJet. I disconnect the dentent linkage from the tranny so as to prevent down shifts. Then at 1500-2000 rpm on the rollers in 3rd gear I nail the throttle to red line.

Since the beginning rpm is below the stall speed one sees torque multiplication on the torque curve untill stall. There is a distinct point on the graph at the point of stall or coupling of the convertor. I'm going to try to attatch a dyno torque curve that illustrates what I mean.

They won't let me attatch it since I did attatch it it in an earlier post. Look in the thread "REV! What did you do?" to see that DynoJet torque curve attatchment.

the fact that the tires are spinning kind of eliminates converter slippage
it seems the driver and the converter just needed a little time to get used to each other a high stall converter will definately change your driving habits
i have a tighter (2800 stall) converter of the same design for sale
