Well, I think the benefits of this thing are immeasurable on a drag strip because obviously it's not going to make much of a difference in HP I do believe the theory can only help bottom end torque & This would or could be part of a tuning package & that would be only with data from a dyno. Looking at a couple graphs could tell.
But the cost to tune on a dyno for this would be plain old dumb. However I'll talk to Tim he's got a 408 on the pump now. Maybe I can make these things and we can get a real world dyno result.
