I dont know if its already on this site but for those of you who are still looking for the speed hack, try MHS6.1
It is pretty much the same thing as cheat engine but it doesn't get detected and if it does you have the option to change a few settings which will make it undetected. Also this tends to get detected on 32-bit systems (i dont know why, a friend who tried this on a 32-bit computer said he got detected). Lasty if you are going to use this dont go over x15 because it will crash and changing the speed every 2 seconds also makes it crash.
