Nelson claims a lot of power, but it really doesn't take anywhere what he claims to blow the tires off if they are real street tires. Or for what he claims, even drag radials. Also a lot of claims about him taking people's money for a build and either not delivering or the engine failing right away. Also yet to see a Nelson engine making some numbers on the drag strip that's commensurate with the power claimed. Obviously part of that requires a chassis that will deliver the power to the track.
So there's several ways for that to be "too much".
