The GV unit will take 0hp away from your normal 3 speed operation where as the A500 is always robbing some hp because it drives thru the OD all the time. They say it can rob as much as 1sec in ET...
I have never seen one scrap of evidence to back up this claim. Not saying it's impossible, but I have never seen anything to substantiate this at all. Until I see a real, all things equal comparison between the two, I'm going to have to put this one right up there with the other myths like the thin wall 70's 440 blocks and low nickel late 70's mopar blocks.
smr transmissions did a comparison on a small block dodge dakota between a 727 and a 518. Lost a full second e.t. with the 518. Same truck, engine, rear and track.
