Well, you just need to initiate and raise magic enough times until you have a strong enough spirit to increase your speed even more. 
Ok but since I dont have the 5e, how much higher would need be the spirit to achiev that threshold of 30% faster than a revolver/pistol bullet (900-1000 m/s)?
The necessary data is all in my post:
Still, a channeled spirit has the benefit of also increasing your physical attributes and you can call up a spirit with a rating up to double your magic (+1 with that one quality). And since spirit rating equals their magic rating you could get vastly improved movement multiplicators
Surged Nocturna with maxed AGI (+exceptional attribute) with a channeled F15 spirit has a modified AGI of 13 and a run speed of 72m/turn. With movement you can tune that up to 1080m/turn or 360 m/s or 1296 km/h.
That's above the speed of sound, so not to shabby (and you better have a spirit co-pilot to help you plot your course)
A turn is 3 seconds, so 72m/turn as base is 24m/s
900m/s / 24 m/s = 37.5
So you need a F38 spirit, which you can theoretically call if you are a mage with a magic of 19.
So starting with magic 7 you only need 12 initiations (354 Karma) and 12 Magic increases (810 Karma)
A small price for being able to outrun a bullet, but being unable to actually perceive it (or anything at all really with those high speeds) 
SHHHH!!!!!!!!
Stop giving away my travel secrets!!!!

I thought you got a point of magic with every initiation
Nope. After you pay for the "privilege" of an initiation @ 10 + (Grade x 3) Karma, You get to shell out an other MR x 5 Karma for the new Magic Rating
But yes, it is SO, SO worth it
