Ive bought a few 5 Packs recently and they dont seem that fast,what are peoples experience with 5 Packs which have you found over the years that are fast

Multipacks can take hit-or-miss performance to the extreme. The vehicles themselves are often downgraded mainlines with sparse decorations and/or have metal parts changed to plastic. Standout performance usually comes from basic metal-on-plastic castings with round wheels and exceptional build quality. I'm guessing that factory assemblers can 'get in the zone' every now and then.
I have found they are hit and miss.
They tend to be hit miss, the same way any mainline is. Two of the same 5 packs can act very differently based on different aspects.
First, make sure the 5pk is from Indonesia not Malaysia...and there is always no guarantees.

What's in the 5-pack is more important that it just being a 5-pack...same goes for the 10 and 20 packs as well...generally with those you have a better case of having straight axels where a lot of the time cars on the blister packs can end up with some wobble. It really comes down to the wheels/casting you are looking for in this case.
