What If Build Ideas...for Land Speed Racing

So, question on the original topic. With limited traction, is it best to have 1200hp with 20% or more slip or 900hp that can get put to the ground? I know that 20% slip from 1200hp is 960hp, so that is more but also what is lost trying to get to speed? Is this more of a concern for a shorter course like El Mirage? Mythical made up numbers but the slip % is what I have heard mentioned via a data recorder on a car from a couple years ago

I was thinking like no prep racing. The hp drag cars without traction can loose to a less powerful car that doesn't spin the tires. Just thinking while at work.
