First off the motor they are selling is making 725HP on a motor dyno. That motor installed in a car, with all accessories will dyno around 600 RWHP. Vince made 560 RWHP for 1/3 of the costs, and it's a STREET combo. The above combo you mention is a RACE combo...

And yes, accessories and driveline will eat up a lot of HP, an average of 14 to 20% depending on the combo...

But you can't base the amount of horsepower absorbed by accessories and drivetrain on a percentage. You use the percentage as a rule of thumb, but at 4500 rpm, say, the accessories are going to absorb X amount of horsepower regardless of how powerful the engine is - why would the power steering care if the motor makes 200 hp or 500 hp? Same for the transmission, unless things are slipping and if that's the case you've got bigger problems. An automatic will absorb a little more horsepower with a stronger engine, but not 200 hp worth or you'd boil the fluid in less than a second.
