I didnt do it in 8 days but it should be possible.
The roads are amazing, there a fuel stations everywhere and you can camp everywhere!
Im not sure where your entering and exiting but the hardest part would be from the city of Bam to the Pakistan boarder. This is where you will pick up an police escort (for free) and you will be stuck under their control. But if you like to speed, your in luck, they will go fast!
I would allow 2 days for this, but if set out really early in the morning from Bam (if your going that way), the police will find you and technically you should be able to get to the border in one day. If your coming the other way, camp on the Pakistan border (you can camp outside customs - there is a small patch of grass and you will be safe). See if you can do all your paperwork the night before and cross as soon as the border opens in the morning. Once you enter Iran you will be made to wait for a police escort to arrive (he will hitch hike 40km - so this may take hours!). I have heard of some people riding that 40kms if
a) your a boy and you can talk them into it
b) maybe if your a couple (they wouldnt let me do it alone as a single girl!)
if you have any other questions, please ask!!
