Got to say as an owner of one of the V8s Tourings they are very fast, despatching most things on the road ( some 911 drivers really do not have a clue - " I am sure that my 911 should be able to beat that family estate car/ wagon but somehow even from a standing start I am always away from the lights behind that thing!!" - 911 driver has to re-check his Porsche badge when he gets home) but there is no way I can see it despatching or even keeping up with the B5 or a B5s Touring similar weight but with between 115 and 145 BHP more and sooooo much torque!! that was never going to happen.
However in a real world situation against an off "guard" E60/61 M5 then there may be a closer race until the E60/61 cam kicks in and thus the extra BHP.
I would however like to see a race between a B10 V8 and V8s to see if there is anything in it!! As most B10 V8 owners I talk to tell me there is not much in it but I suspect this is not the case ( especially after talking to an owner who, is not a member of this forum but has owned a B10 V8, V8s and now a B5)
Add a few corners into the race and the result may be a lot closer as from the reports that I am getting and seeing the B5/B5s is faster yes but not more fun and maybe not as good at putting its power down when cornering, without that optional diff, but maybe this is the price of progress. Each evolution of the model seems to remove the driver input more and more.
We shall see.
BTW Gustav should I come to Sweeden I would be happy to supply the B10 V8s Touring
As for father and son I think A.G. means that this was a father and son team driving the cars not that the B5 is the "daddy" because on that I may have to disagree.
