The engine should be just like the previous Speeds. Not sure the exact internal changes from the MAG or AL versions if any, but I believe we have one or two at our track and it seems to run just as good as the previous models. Changes on paper are the lightned head and reducers supplied. Comes with 6mm, 6.5mm & 7mm now compared to 7mm, 8mm, & 9mm on the previous models.
