It may not show as much boost as a cam with zero overlap, but with a blower you have some of the airflow (as you say bleeding off boost) that clears the cylinder. This is a common misconception, just about any cam will work with a centri.
Since turbos have backpressure it needs to spec'd a tad different.
My cam is "wrong" because some people might say its to big for a blower car... but it seems to work good for me and it was cheep. There a probably better cams, but its a cost vs. performance thing.... if you already have the thing put it in, it will def. make more power than a stock one.
500+ cars on street tires are really kinda silly anyways..... If one cam is down 15rwhp vs. another is it really a big deal?
