What shawnp said....
Question....has is been down the track yet? That would really tell the tale. As stated repeatedly before, we don't race dyno's and they're all different.
Here's an example...a guy I know has had a 968hp 565 and a 1101hp 588 from the same big name engine builder, dyno'd by them and he has the sheets. The car is a swing arm dragster, 1870lbs, and ran a best of 7.81 @ 171 at about 7800ft DA with the 565 and 7.61 @ 174, similar air, same track with the 588. Personally I think it should of picked up more than .2 and 3 mph for an additional 130hp and an additional $5k.......is it the dyno, the car, the combo, or just high expectations?
That being said, I wouldn't expect to get 1100hp for 12k regardless of what was said, written or assumed.....some smokin deals are just that, smoke......
