Yes I run one. It a great engine! VERY fast! I run it in my truggy. I've have about 3 races on it now. The first race was an indoor race for our regional pro series. I was able to pit at 10:30 without a problem. Now last weekend was an outdoor race on a track I was comfortable with so I was driving the truggy STRAPPED! lol. I was only able to go about 8:30 with it so I pitted at 7. But its a very good engine.
