Yes. I don't have one, but that is why. They have a problem with overheating if used regularly for extended periods of time. That is why so many people are looking for old A4 blocks instead of using a new R302 in a street/strip car. They are great for all out drag cars though. They will handle insane amounts of power. I was going to get one until I heard of this problem, that is why I also am looking for an A4 bloch instead. Light Em Up!!
