Dave E. gets his hacls up over:
>still ducking and diving scott?

"Ducky" in the rain, and that's driving, Dave.  Should have been at the Road 
America National qclub event watching spiders bite torsen cars in the rain.  
More spins and offs in a single day, than I've seen in 8years of qclub events 
(not one locker went off, hmmmm)....  Oh yea, the "challenge awaits"

Most reasonable, in fact.  Dave, in deference to spilling my beer again, 
let's take a look at your challenge....   To really look at 1, you could 
(simple steps, thank you... Dan) go to the archives new search engine.  Using 
it, one could find both the "simple" and the more, er... complex models 
(thanks to you directly, dave).  Appreciate your efforts to put it up again, 
but Dan has been most lenient on this thread already.  Are you sure we need 
*more* archives on this?  

When I look at 2...  Agh!  I've just spilt my Fosters.  QSHIPQ ponders:  "Why 
would Dave E. pick a couple cars that he doesn't own, and probably never 
drove, for comparison purposes".  Hmmmm....  Could it be another infamous 
"white paper" perhaps?  :)

A couple things in reference to your recent threads to date come up in that 
very "white paper" Dave.  1) reread the "Vehicle Behavior when braking in a 
turn".  Why is the torsen described configured at a 75/25/75 split?  Next 
question:  If the non abs group B rally cars "ever" ran torsens, do you see 
any need for such a high torque split?  Any advantages to having *less*?  If 
the weight distribution of the S1's posted by Jouko and Hans are correct, any 
thoughts as to what torsen ratios might be used (if any)?  2)  Look really 
hard at the "assumptions" in the section "Vehicle Behavior when Accelerating 
in a Turn."  Then reread that section with the "assumptions" in mind.  Any 
revelations come about?  I find it amazing that you would pick a "white" 
paper to make your stand, that describes exactly the spider bite phenomenon.  
Great show Dave.

Now that you've peaked (as apposed to being peaked in waning interest) 
everyones interest, maybe you can make that white paper available to the rest 
of the list.  I'm also thinking that you might want to get some more white 
paper on the VC differential lock, you stumbled so badly there as well (and 
really pimped toyota and yourself, since there *was* a torsen run in the WRC 
- uh, that's in the rear of course:).  The torsen white paper you picked to 
wipe me with (pun intended:) is pretty complicated for one looking for 
"simple" concepts.  To put the 80q v 80q  in perspective, maybe you could 
explain what results you'd expect and why, if both cars tested had only a 
driver in them, instead of "maximum permissible load".  

I'm laughing at myself first, THEN lapse into silence as I wipe up my beer.  
Given your "challenge" I could have had a lot more fun, but I'm peaked.  
Really dave, you need to get out more...
