I think the answer is no, but could a relatively extreme driveshaft angle affect a chassis dyno reading?


Thanks guys.

Matt

Also can anyone tell me what the min/max angle you would like to see (pos and neg) for general use isses?

I don't know the right answer. But I have noticed that when I use a universal socket on a ratchet, that the more angle on the universal joint, the harder it is to turn the ratchet. If this is true with drivelines, then I would say more angle in the drivline will require more power to turn and should show up on a chasis dyno. I am not basing this on any kind of scientific calculation, just what i have noticed. More food for thought!

Good article in Hot Rod this month on the different types of dynos and all the variables that affect a dyno run...........

I wasn't aware how much of an effect the way you tie a car down can affect the numbers of a dyno run.Interesting read.

Marv simply put yes...Theoretically You want the driveline to be deadon for maximum efficiency. People set the angle down a few degrees to increase traction. When you accelarate the angle changes as the weight shift the the few degrees down neutralize...as far as i remember.just an fyi happy hunting

Doggy has the angle bit down right. When you accel you want the angle neutral thats why you run a negative degree while standing still.

Though, on the dyno it should neutralize also, because the forces turning the from of the diff up, are there. You just dont get the weight transfer for more traction purposes.

Sounds like if your pinion stuff is way out, then it'd hurt ya.

You are obsessed with this thing! :D
