Because Gurren Lagann needs more boosting 
The feat can be found in episode 24 of Gurren Lagann, around where Ailac and Kidd die.
Spoiler:
(3474.8/78)20.4=908.8km
Spoiler:
Chouginga-Gurren Lagann's face is Chouginga Dai-Gurren's face, so...
908.8(3)=2726.4km for this blue head thingy on the giant face's forehead.
Spoiler:
2atan(73/(580/tan(70/2)))=10.072880467714
So our distance is 15468km.
The missiles reach the frame 45 frames after they are launched. With a frame-rate of 24fps, this leaves us with a time-frame of 45/24s.
15468000/(45/24)=8249600m/s
or about mach 24,264.
Darry's Grappearl bullets and Yoko's Dayakkaiser bullets massively outpace this, and their shots get dodged all over the place by scrub hands and feet. Plus, Kidd and Ailac match this speed, so there's that.
