What kinda hp am I looking at?

Ok so say I took an xr50 and put a turbo on it. Stretched it about 20 inches. Put some training wheels on it with pro wedge pattern. Im thinking boring it out to like a 70 to unleash the true power. Definatly a pipe. Or no pipe at all. Im thinking possible contender for quad wars 2009? training wheels count.
