I just dropped one of these little beauties in my 8 a few days ago:
It's been awsome so far, only have about half a gallon through it, and it runs like a champ. No flame outs once it's warm, and plenty of power. I hung with several different motors down the straight section at my local track. This includes, a P-5, and 5 port version RB, and several other very fast motors. It's worth every penny, and a fantastic value comming in under $200.
