I don't think anybody posting here can exceed the power capability of a well built 8.75 in a road race environment, and if they did, they would be at the top of the list for bragging rights.

The original twin turbo Cuda in "projects" forum would be an exception. Big Sticky tires, upgrade/optimized suspension, some aero, and big motor for salt falt runs would IMO start to reach the limits. And a 8.75 vs most others saves a few hp in friction losses and at that level might be important.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
