twin screw blowers just can't keep the breath flowing at that level.
I know all this numbers, but i think is something special to hear the whine of the supercharger in your back plus the image of the supercharger belt in you rear view mirror, even if you haven't the power of the TT system

People on viperalley llooooovvveeee John from what I have seen so I wonder what the real story is. I read over there about them having problems in the past but that not being the case anymore. I have no experience with Hennessey, Heffner, or Underground just adding what I have read in case John has been able to turn things around.

My thoughts exactly. I wouldn't send my Schwinn to Hennessey for work to be done.
