I just looked up the specs on the Twin 200 on horizon's site, they don't list the power. I have a feeling you might be better off with a 180, definatley on the price side, $350 cheaper, and maybe on the power side. But if you have the extra $350 to blow, it would be pretty freaking cool to have that big twin in a Mustang. I bet that is why Hanger-9 put out the 150 Mustang, to promote the sale of the 200 twin.
