As you probably saw in my video that speed was increased a good amount with the Window Turbo, I don't know if it adds torque but I know my passenger window on my Regal really struggled pushing the window all of the way up that last inch prior to installing.I’d still like to hear some feedback from the guys that have made their power window motors faster, guys are they any more powerful as well? Steve (pontiacgp) I know you’ve added relays to yours as I remember reading about your struggles with them, care to weigh in for us? How about 565BigBlockChevy?
