NRHS is very well known for their performance products. Frankly I don't understand why some people looking for performance add-on's for their bikes think SE products are the answer because it's stamped with HD's blessing and of course their profit margin.
Some SE products are very good. The old SE a/c was really everything that you needed for a good price. The new SE is a POS. In addition, look at the dyno room at NRHS and look how many of those big power bikes are using SE cams. I would say the majority of the better performing bikes are running SE cams.
I have the hurricaneflow and it's a good A/C, but my biggest problem with it is the weight. That thing is HEAVY! It's a good 2-3 lbs heavier than most A/C's and that's a lot of weight for an air cleaner.
