Few teams have their own dynos, because drag cars don't have to change shocks for various tracks like a round track car. We don't really need low and high speed valving changes from track to track. On a drag car, once you get out about 100ft, the shocks do nothing but absorb bumps in the track. Shock control at the hit is what matters.
That said, you do see some shock guys at the tracks these days with dynos, testing and setting up shocks
