Last week, we shared Part 1 of Pete Nichols from Hughes Performance introducing us to the company’s Pro Series torque converter dump valve kits.

They can provide competitive performance gains in drag racing applications.

In Part 2 today, Nichols is back to talk specifically about the Hughes Performance Pro Series 2 Stage torque converter dump valve kit for Powerglide, highlighting the differences between this and the single-stage kit highlighted in Part 1, and explaining the science behind the two-stage dump, increasing stall speed and providing an even-greater edge in the right applications.
