I came across an interesting thread in another forum. This was the question posted....
Due to the way the transfer box sends torque to the front wheels on a GTR, does this mean that while on a four wheel drive rolling road the transfer box is working at full load for the duration of the run?

If so, is the load transmitted through the transfer box way above what it was designed for?

Therefore is there a risk of damaging the transfer box?

Also would this give an incorrect reading from the rollers as the power being transfered through the transfer box will take away the full bhp being produced?

Anyone got any thoughts or experiences in this matter?

Having abit of difficulties coming to a conclusion as differnent people have different opinions. What do you all think? Should or shouldn't GTR's be using rolling roads/dynos?

The thread is at the GTR.co.uk http://www.gtr.co.uk/forum/upload/showthread.php?t=45059.
 
In my opinion, the RB + GetRag's in GT-R series are designed to take pressure. I dont think Nissan designed something which will face future problems, Skylines been on earth for 20yrs and there isnt any problems rose :)
 
Why would the load to the transfer box on the dyno be more as compared to the road? In actual fact when the dyno isn't 'loaded' the rolling resistance on the dyno is alot less thenwhat you get from being on the road.

Why would there be an incorrect reading from the rollers when power is transfered to the front via the transfer box when its a 4WD dyno in the first place?
