[DMCForum] DMCH performance engine specifications

["twinenginedmc12" <twinenginedmc12@xxxxxxxxxxxxxxxxx>]

I'm sure the DMCH performance engine is a fine engine, but it should 
be noted that the power specification they publish does not 
accurately compare to the stock specification.

The OEM stock engine was rated 130 hp "NET", by law, which means the 
reading is taken with all accessories like water pump, alternator, 
air conditioning, intake, exhaust, etc, connected. 

The DMCH performance engine is rated 197 hp "BRAKE", meaning the 
reading is taken with no accessories connected.  There doesn't even 
have to be coolant in the passages.  In the nineteen seventies, the 
Society of Automotive Engineers (SAE) abandoned specifying brake 
horsepower (BHP), because it does not accurately reflect the power 
available to move the car.  

Unless Delorean in Houston starts specifying their performance engine 
in NET horsepower, it's not possible to intelligently compare the two 
engines.  I consider DMCH specifying their horsepower in BHP either 
misguided, or somewhat deceptive, depending on their motives, in that 
it leads people to believe the performance engine is more powerful 
than it is.  This is precisely why the SAE stopped specifying power 
this way.

what a fun car.
