Torque at rest will not change at all. The high speed torque will improve
about twice at any speed above a crawl. And, so, whatever your top speed
is now (I'm assuming you are limited by the motors losing steps) should
roughly double. Also, your motors will run quite a bit hotter. I'm
guessing those big motors run pretty cool now, so that may not be a problem.
This is a 50 VAC transformer (or 100 VCT with a 2-diode rectifier)?

(If your speed limit is due to the computer's speed at producing step
pulses,
then you'll get no benefit, of course.)
