    Default Experiences with hp enhancement with a Weiand 142?

    A guy at a local speed shop insisted that a Weiand 142 is going to add around 200 hp at 6 lbs of boost on a 350 crate motor that's supposed to be rated at 355 hp. I haven't put the car on a dyno yet, what I've read about a 142 is that it's good for somewhere in the neighborhood of 80 - 100 hp.

    Is this guy full of it? If you've had a 142, what kind of hp enhancement numbers did you see?

    80 - 100 hp is closer to what to expect...
