The answer to the question asked does not require any confidential information. By "educated guesses" I was not referring to sharing confidential data. I was referring to people with knowledge of how to modify a Viper V-10 to bump up the HP by 90 HP. There are a number of posters,like Mr. Dell for instance, and tuners, who post on this site who have this level of knowledge. The other data which was the subject of this post, as stated above, was not subject to confidentiality and or franchise agreement restrictions and appears to have been intended to start a sales/marketing buzz about the car.
So, getting back to the subject, any ideas in addition to the dual throttle body idea, on how 90 more streetable, reliable, driveable, everyday horsepower is being produced? I would guess: different intake and throttle body, different heads and valves, different cam, and, perhaps, a somewhat modified fuel injection. I base this, in part, on what Woodhouse does in their Stage Five naturally aspirated package. The package generates 80-100 more HP. I do not think that DC would use boost on the Viper since DC is moving away from boost on its AMG version Benz's. I do not think, I am guessing, that they were comfortable with how easy it was to modify them with a pulley change and a tune to produce very significant power increases.
