Brian, it is a chassis dyno. I'm not too worried about hp figures, as I'll believe the results at the track more. I'm only wanting to get my new Alky carb and timing tuned in. This is my first shot tuning an alky carb, so I thought it would be a tremendous help to use the AFR readings of the dyno to get me in the zone quickly. Hopefully save me having to spend a whole day tuning and transporting at a track.
