Well instead of insulting me, try and answer my sepcific concern! 
In one of the many shots fired from your fact gun, you aimed an insult bullet directly at me, claiming I believe in fairy tales…
Please quote me correctly. I merely ASKED who had provided such info, to your very specific claim of 70% going to the rear.
And if you did feel that I made a "personal attack", then I apologise, as it wasn't meant to be "personal" at all.
As an owner, who’s driven thirteen thousand miles in an R32 and had the Haldex controller fitted...
And I am speaking as a highly qualifed Automobile Engineering Technician, who fully understands the detailed operation of transmissions, and particularly four wheel drive transmissions, and has spent many, many years working on such systems.
And I add to that my own personal experiences of driving various Haldex cars - albeit with just the "standard" Haldex software in the controller.
I can confirm that if I put it in Race mode and perform a standing start, there is an unquestionable sensation of being pushed down the road rather than pulled. It sometimes feels like the fronts are doing nothing at all.
I don't question that at all, and I fully understand and agree with you. And it is simply down to weght transfer during acceleration which creates such an effect.
I understand the car is not permanent 70/30 RWD bias but if you really think that it can’t shift more than 50% to the rear wheels then you sir, have never driven a MkV R32 in Race mode.
But I am sorry, I have to disagree with you. Please tell me how the Haldex unit is able to disengage the drive to the front axle? It can NOT do so, because the front axle is permanently driven, irrespective of what the Haldex is doing. The Haldex is simply a clutch, and not a differential, and so it can NOT dynamically apportion torque from one axle to another. At best, irrespective of weather the Haldex is standard or "race", the Haldex unit simply locks its clutch at a clamping force of 100% - and this simply locks the rear axle to the front - meaning an exact 50:50 bias.
With your "Race" mode, what is actually happening, is that the Haldex is locking its clutch
before you move off, thereby giving and exact 50:50 bias, but, because of the weight transfer effectively being pushed to the rear of the car during acceleration, it then "
feels" like the fronts are doing very little, and the rears feel as though they are doing the major share of the traction. The
actual apportioning of drive though can be no more than 50% to the rear axle.
I would take my own experiences and manufacturer info over a bloke on a public forum, no offence.
Firstly, no one is doubting your "experiences". However, what you "feel" through the seat of your pants is not the same as the fundamental priciples of Automobile Engineering.
Furthermore, Haldex Traction have repeatedly been found to "fudge" their figures, and squew their claims. Haldex make incorrect claims by ignoring the "industry standard" of describing vehicle dynamics. Google "Vehicle Dynamics International", blag yourself some free tickets, and then speak to some of THE most eminent professionals of the motor industry - and not one will back up Haldex Tractions' methods of describing the distribution of drive in their four wheel drive systems (or the way Haldex "discredit" 4wd systems with an ATB centre differential).
Kind regards.
