Right now I figure it is about 180hp. I still have room to turn it up. We will see after I get some more miles on it and get a few bugs worked out. I only have about 100 miles on it so far. And only about half that is on the pavement just driving it to work. The other half is cruising the dirt roads and field roads. Which, don't get me wrong, that is where I would rather spend my time. But I would like to get some more road time to check temps, etc... Right now with all the salt on the roads here I have been keeping it to the dirt roads. It does have plenty of power to move the 40 along. I am looking forward to seeing how fuel economy does and how all the temps do this summer. I am trying to use this winter to get all the bugs sorted out so that I can enjoy the rig this summer!!
