If a wheel is slipping than it is not delivering any power, is it? The ring and pinion is all part of the back end system which incorporates the differential. The system in its entirety needs to function as a whole, which means that a part is not necessarily bad, but rather that the system is not working together properly and that relationships must be changed. The entire point of that article is that they had trouble putting the car together and that they made mistakes that they learned from. Do notice the point about speeding through the mustangs dust cloud and its testimony to the performance of the Iso-Tourqe. You are completely missing the point of the article and ignoring the letter that was written way after the race. How you equate this to be troubling I do not know. Its a wonderful letter of praise and a statement of validation. They rushed to put the Diff in for the race, made some mistakes and paid the price by overheating the rear ends cooling system. They changed somethings around and now they are running 2 seconds better on each lap (in case you were wondering, they do practice at race courses, nopt just see them once a year). Please define the problem here, I do not understand how you can even remotely equate these things to being disturbing.

It's delivering more horsepower than the normal diff because it isn't binding or slipping. Besides avoiding the inefficiencies of traditional designs it is also giving race teamS the huge advantage of not having one of the drive wheels spin out of control.

Considering the blown engines, shorts inside fuel tanks and cobbled together brake systems, I'm not surprised the same team that crippled their diff cooling system for a qualifying run, missed getting the diff cooling setup right. As I said, judging from their enthusiasm for the extra mph out of turns, they will use whatever fluid/radiator combination they have to in order to keep the Iso-Torque happy. The bottom line is this racing team has gone on record as saying that a heavy, down on power compared to other racers, formally not that competitive, racing 350Z has a shot at being a winning racer largely due to a new diff design that lets them have a large advantage over other racers. That's my reading of the tea leaves. Others have a more dismal take.
