as a racer, I would say yer well over 200hp, probably closer to 300. I've seen a couple sleds turn 100-110mph in 500', and that is a friggn balls to the wall race sled, built from the ground up to go like hell. ya, probably atleast 250-300hp, and that's a minimum, I've heard of max-4's putting out over 400 for drag raceing, and those are still barely touching 150 in the 1/4, so to make that in 1000' that's pretty insane
