I remember seeing that one BB1 prelude making 230 at the wheels and getting the impression that it was pretty tough. What is the ceiling on all motor power and what kind of timeslips would that get you?

 

Your wallet determines the ceiling for your "all motor" power.

Seriously though, search Satan SRV's archived topics to see before and after dynos of his build. I'm not sure if he included the cost of the build but it will give you a general idea of what it takes to make all motor power. You may also want to check what other people ( 2point6) have in their archived topics.

 

Also depends on drivability (money factored in).

You can easily achieve tons of N/A power by running race compression 16:1, sickly aggressive cams, etc.
