I don't think you understand. We aren't talking about the ability to adjust bias based on slipage, which is what the nissan currently has. It does not have the ability to adjust based on gs and other inputs. The same system is in the 911 and its not some huge leap. Which brings us back to my point re: historical inference does not backup the assumption that a huge jump in bhp will occur.

Essentially what your trying to argue is that when going from a 95 percent lockup to a 50/50 lockup your getting more driveline loss. While true, its not historically true that it would be as high as your thinking. While coupling the rollers would eliminate this issue entirely, even seperate your not going to lose massive amounts of power.

Heres a good writeup to what im refering too:

Speaking of which, the whole 25 percent driveline loss bit is a bit of a farce anyway. Take a 1000 bhp car. Theres no way in hell it could lose 250 through the driveline. The losses go to heat. Could you imagine how hot the axles and transmission would be? RC mentioned a number for the z06. Im not even sure I buy it honestly. If we go purely on the sae certified number of 505 bhp and an observed dyno of 450-460 by most owners, that nets out to a 10 percent drive train loss. It would make sense that a 505 bhp skyline, assuming a 5 percent variance in output from the stated 480 bhp which happens alot actually, would have 430 bhp due to the inherint extra friction as part of a two axle system. The difference in this two axle system, if information from the 911, lambo, et all bear as examples, would actually come close to reflecting a 430 bhp output. Under that situation switching to rear bias should only get you back up to the z06s rwhp. It should not allow a trip beyond significant enough to overcome driving around rosie odonnel and two of her fat friends in the trunk (aka the gtr). Which again proves the point the car does not have significantly more power then the z06, despite significantly more weight. Which begs the question, how are cd seeing the acceleration they claim? And why is road and track hushing up the slower traps they saw?
