Here is a good graph of the ECS Centri System featuring the Paxton Novi 1500 Self-Contained head unit (Unlike other Centri systems a lot more down-low torque) vs. a Maggie car... The nice part is the ECS system has great amounts of torque, but is not a tire shredder down low, also have nice linear power so you are pulling hard upstairs.
Here is a quick comparison, now our kit was running 1psi more up over 6000RPM's than the Magnacharger did.
