Hey Matt,
Any news?
I tried to check your site, but it is down, and it looks like this thread got very slow as well. Now that th weather is getting nice again, I am getting all my stuff ready to run. I need a 17.5 for my truck, my son is going to start running this year in Rookie. I will have it dialed way back til he gets better, but I see no point buying a lesser motor as I will want your power once he can handle it. My crappy 13.5 that you out ran with your 17.5 is now in my 4WD buggy, and with a Mamba Max Pro pushing it, it runs far better. I was going to use it for my son, but thye really want only 17.5's in rookie. Hope to see you by Hot Rod some time.
