Assuming you got a cyborg sprinter that can go much faster than what humans can due to superior power out and acceleration, how fast could he go before needing to optimize for airdrag?

It is more likely you would run into mechanical constraints well before any air drag issues. Peak dynamic load on the joints, even with advanced materials ...

hm well for air drag i would say it is less than c

What work have you done so far? What did you find in the literature upon your review?

I went down a rabbit hole of reading through thought experiments of assuming a hypothetical scenario in which humans can design an indestructible human machine, and that the mechanics of the human body’s gait are ultimately the walls against higher speed. It was concluded that the fastest possible speed for a human-like creature running on two legs was somewhere in the realm of 45mph, it’s just not possible to hit the ground fast enough to continue moving the body forward past that barrier even with optimal conditions, at least on flat ground.
