just curious as how youd do a dyno on an AWD vehicle? havent really had any experience with dyno but the set up is only for 1 set of wheels (whether it be RWD or FWD) isnt it? is it even possible to do a dyno on an AWD?
probably a stupid question but i thought id ask.

They have dynos that all 4 wheels rest on.
Its the same as the normal dyno except there is 2 rolly bits.

With some AWD cars they dyno rear wheels only. Namely, Skyline GT-Rs. You pull out a wire from the ATESSA AWD system and the car becomes 100% RWD, which is why so many high power GT-Rs have like 800rwhp instead of awhp. Same thing can't be done on simpler AWDs, like a WRX.

i have seen some all wheel drive dyno's that jack the car up take your wheels off and a large box type unit bolts to the hub.

i would have thought the easiest way would be to unbolt the rear prop shaft and dyno it like a fwd.

Half right - R32 you pull the fuse, R33 you have to get a chip installed, R34 you cannot disable ATESSA.

this takes out the inaccuracy that wheelspin results in.

ive seen a jap fellow at a street race on a "private road" who popped the bonnet on his r34 gtr do somthing and make it rwd only. Got me stuffed what he did but you could notice once he took off the rest of the time as the ass would step out.
