What is the proper method for checking the stall speed of a torque convertor?

[Two Lane]

LOL...this thread reminds me of the '70s when everyone "discovered" Vega converters had lots of stall behind a SBC, really waking a car up off a red-light...super-cheap, too...lots of fun...while they lasted!

Converter stall-speed is a lot like cam duration...the same converter & the same cam will behave differently in different engines, based on the parameters of the particular engine/powertrain.

There is no off-the-shelf, one-size-fits all.

Keeping the above in mind, rather than buying a converter based on advertised stall speed out of a catalog, you'd do much better calling the trans/converter shops direct to discuss your individual combo & plans.

Then, you'll actually have the optimum unit chosen specifically by the professionals for your unique set-up.

I understand what two lane has said. I am not new to this.
The reason why this question was posed was because it seems that there is no method of checking stall speed. This was a custom convertor that according to the detailed information I gave should stall at 3500 rpms. So my question is why do I get 2850 at 0 and 3500 at 10psi?

BECAUSE STALL SPEED IS DERIVED FROM INPUT TORQUE ,THE MORE BOOST THE MORE STALL SPEED.WHAT IS THE REASON FOR CHECKING AT 0 BOOST?I THINK YOU WILL BENEFIT FROM RE READING MY POST.WWW.CKPERFORMANCE.COM
