Dyno Day (11.15.08)
That and it wont come close to Nissans claimed times on the Nurburgring ;-)
In all seriousness, I woke up in the middle of the night with this thought, can the GT-R display the front/rear torque split? I would like to have seen what that was for the Super Rupair dyno.

....What really is a bummer for the GTR is that the cost of repairs is higher than porsche for a car that comes in at half the price. makes no sense. that is why I think we will be seeing second hand GTR's with voided warranty's going for very low money in a couple of years. Nissan screwed up with the tranny and they are not admiiting it. because of the class action lawsuits currently in place regarding the tranny, they will eventually make changes and improvements.
But for now if you have used launch control even once, your warranty is void..period. and if you blow the clutch, the cost of repair is $20,000 because you have to replace the entire transmission.

why? what difference does that make??? I am sure most of the power was going to the rear wheels.
I was interested in how it handled the dyno being AWD- Im still interested in dynoing my car, but not at the risk of damaging anything, I have dyno'd at Revolutions Motorsport in CoS previously, perhaps we can setup a small event.
Now go have your cup of coffee and log back in :-)

Torque split was in the middle with the GT-Rs on the guage, ever so slightly wavering and compensating throughout the pull. It did waver a little more until full load but stayed in the center under boost. I dynoed a BMW335 Xi automatic this morning. It also displayed a nice torque split. I can actually put the bar screen up and watch torque split on the dyno real time as well.
BTW, Revolutions in the Springs is a great place and they also use a Dyno Dynamics dyno. Adam K. is a very good friend and I supply them with a lot of Autronic SM4 standalone ECUs for Pro Rally. We see eye to eye on tuning theory and like to compare notes regularly. We also trade unsatisfied customers, who then realize that their readings are proper. His Dyno Dynamics is better due to twin retarders for the rear. It can handle 2200WHP uncorrected on the rear axle versus our 1100 WHP. But either should be fine for most performance cars as the torque split functions are identical.
I can help facilitate a meet there too if you wish.

Nissan GTR: $70k
0-60 in 3.5 secs with Launch Control / VDC
Broken transmission: $20k
Warranty coverage: $0
Look on owners face of multi driver household while dealer explains warranty invalidated by (unknowingly) using launch control: PRICELESS!

With $20K, you can buy a 2004 Audi S4 nowadays!

all those acceleration stats are using the launch control, so, now 1/4 will be about 1/2 second slower, but less chance of replacing a 20k clutch. The next step should be an optional manual trans for 8k less bringing the retail down to 60k.

That should be the only option. GTRs never had tranny problems until now.
