I must admit, for the price, I love my Novi 1000. I paid $1,700 for it, and it's worth every penny. I am at 4,100' elevation, and the car picked up 1.1 seconds in the 1/4 with the blower and a set of slicks in this air with the stock pulleys on it. And for $15 more, I was able to bump the boost up fro 4psi to roughly 7-7.5 depending on the weather. For a good message board on blowers, try
