I take those 1/4 mile and horse power calculators with a grain of salt. They DO assume it's a perfect world, every shift, every hole shot, no tire spin, humidity, density, etc. all "perfect". Also perfect gear ratio's! Your in high gear at max rpm JUST as you cross the line. You've used it all up, nothing left.

I think the horse power calculator based on trap speed is perhaps a little more accurate than the ET calculators though. You could turn a relatively low ET and have an awesome trap speed mph, for instance. Trap speed is what typically separates a small block from a big block car. Small blocks spin up to rpm quicker, often a better hole shot, but they flat run out of power at toward the end. Limiting their final trap speed mph EVEN though they might have won the race!
