[DMCForum] Re: perforance engine specifications

Hi Mark.

That's it in a nutshell, though we can't presume that DMCH 
deliberately out to deceive anyone.  It could be an honest mistake. 

A good example of brake vs. net power specifications is the 1970 
cadillac engine in the back of my car.  It's rated as 400 brake hp.  
2 years later, the same engine, with a slightly lower compression 
ratio, was listed as twohundredsomething net hp.  The majority of the 
difference is attributable to the change in going from brake to net 
specifications.  

Rick.
