My advise to you is go back and search through this forum ..there are previous threads all about the nx76 and truckzilla..you will find the july05 issue of nitro magazine dynoed the nx76 at 1.58 poneys and 75 inch pounds of torque..........There are different dynos out there,but that is a huge difference from the 5 horses claimed by cen check out nitrodyne systems.com
