It all depends on the people queuing at that time. If it's a slow night and you're in, say, Adders - 8 man pre-made would be faster but the same time an 8 pre-made in Flames would be hell of a lot slower due to how slow Flames queue is in general (lots of solo people queuing)

If it's a fast night and there is a lot of solo people queuing, you can go as any size group. As my friend in my FC said, the queue is just like lego bricks, if there is a group of 3 queuing for 2 hours already and a solo person and a group of 7 just queued, the group of 3 isn't going to get the pop.

also coo. I miss laughing at your random coos in matches man, so hilarious.
