I think he needs alot more than the center diff! lol!! j/k

I was using Rb's and Novarossi p5's and couldn't grasp why anyone would spend the extra money on those sexy blue headed jp's.... Then I drove one! I have to say they were the most linear engines I ever came across. And you absolutely could not out run one. Got really good run time to boot. Needless to say after the first we never ran anything else on our Mugens.
