says "all signs point to yes"

LOL

but earlier today I saw a vid of a 1000hp turbocharged e30 m3.....there is always a bigger fish 8^)

I'd be glad to take your "bait" off your hands if you feel the need to go and pursue bigger fish!

LOL!

j/k brother... see you friday hopefully!

must've been a swap from e36 or m5.

...or 10,000 rpm redline, and by the time it is making full boost, k04'd s4 will be crossing the 1/4mile finish line.

Numbers are either inconsistent or awfully low, however the performance of the car itself seems to indicate (well to me at least from what I've been reading) is that the dyno numbers aren't right.

WOndering if the 60/40 torque split has something to do with it on these dynos.

Pretty sure that has something to do with it. If you think about it, you got different amounts of torque going to the back and front, which translates into the rear probably rotating slightly quicker than the front, thus the torsen compensating to even things out.

While I have no idea how this affects the numbers, I would guess that over a short period of time, the torsen should automatically adjust to distribute a 50/50 torque I'm guessing, but I'm no torsen expert!

I'm not a Mechanical Engineer, but I don't see any weight transfer to the back to keep the 60/40 split going when on a dyno.

Torsen reacts when there is "slip", so really, when one turns quicker than the other and guessing the rear first because 60% of the torque goes there.

I understand how torsen works. But then what's the point of having it default 60/40 from a standing start when it will pretty much instantaneously go to 50/50 due to no slip?

I guess this is why I chose EE instead of ME back in my skule days.

I believe all wheel dynos can compensate for this. different all wheel drive cars will have different torque splits. the electromagnetic 'retarders' that dynos have on the rollers are supposed to be able to handle various torque splits.

even with the 60/40 split then, I'd assume that a properly working dyno wouldn't let one set of rollers spin faster than the other.....it should apply metered and measured load to the side with more torque.

Remember, when it's on the ground, you're moving along the *same* pavement, so the rate of change is going to be the same as the front and back, unless the front it slipping due to it understeering through a corner perhaps or on snow.

On a dyno, the two masses that are being spun are NOT "connected" together, they're allowed to spin at different rates if the conditions permit it to.

At the back, less in the front. Less grip in the front means the TorSen shifts the torque to the rear. So under hard acceleration it could be that a majority or up to the 80% of allowable torque is shifted to the rear.

Car on another dyno could/would produce better dyno numbers.

Assuming the usual 25% drivetrain loss and a starting point of 414 BHP the estimated WHP should be around the 310 to 315 range.

do clutch the rollers together, preventing difference in roller speed. However inertia type dynos, such as a dynojet (i believe), would allow rollers to spin at different rates.

Hmmm this sounds like one of those questions on OT.... does a plane fly if it's on a conveyor belt :)

Now that I've finished my morning coffee I think I know why there's still weight transfer.

Ugh, I think I need something stronger today. Bad move in drinking a tall can of ice tea for dinner late last night and couldn't fall asleep with all that caffeine in the system.....

On the dyno I do all my pulls on, a Dynapak hub dyno they can actually show you on a graph where the power/torque is going and I can assure you there is more going to the rear on my car.
