Yes I realize boost is more a measure of restriction. But I did not know what kind of cfm the novi 1000's flow, and I just wanted to make the point that they are capable of spinning a lot faster than the stock pulleys they come with. From what I read, it seems like he has a mild 347 which I would think he wouldn't spin that high to begin with. So if you do choose the 1000, you would want to buy a smaller blower pulley to be where you want.
And supposedly the 1000's can be pullied flow a good amount of air for an entry blower, although when pushing it to it's limits, it's not going to be as efficient.
