cool, id like to have one to interchange at the shop. the way it plays out to me is all the torque will go to the front wheels and at least allow me to load the car on the dyno to get accurate a/f readings. and after looking at the comparisons it looks like only about a 2hp difference between an AWD pull and a converted fwd pull. thats according to the info i got from a guy at MD where I bought my dyno who actually has a 2.5RS and has done the back to back tests in house on both an AWD and 2WD unit. I know its a pain in the ass to switch the diffs out, but i figure i'll only really need to do it once to get the tune right. and I usually pull all nighters on the dyno when i really get focused so i would imagine renting an AWD dyno for 24 hours would be a bit on the pricey side.
