theirs too many variables involved on a dyno. You have to factor in weather conditions, air temps, etc. On a dyno you have none of that. And yes i have seen both intakes run..both on supercharged cars. one on a 15lb t-trim and the other a 13lb procharger. And the rest of the combo's were pretty much the same. the one with the holley (procharg'd car) outrun the Edelbrock equipped car.
