In such conditions, we've heard from NMCA EZ Street racers that the Moroso pump can be worth as much as 40 hp at peak on small-block nitrous engines. They work by producing high crankcase vacuum, which increases power by improving ring seal, preventing blowby, and detonation. Sep 6, 2022
The nature of a vacuum pump is to remove, air, blow-by gasses and other contaminants from the crankcase of an engine. Built for racers and engine builders who craved the performance, Moroso racing vacuum pumps are manufactured from billet aluminum and feature a precision-machined shaft, rotor, and bearings that will withstand the rigors of racing.
Morosos Scott Hall covers some frequently asked questions the company gets about vacuum pumps at idle. These positive pumps are much more consistent and effective than header-mounted evacuation systems. 
Moroso offers many ratio options for two reasons. Hall explains how a pump functions to produce vacuum and how someone can get a better reading on how much vacuum their engine is producing. Besides improving ring seal while reducing parasitic power losses on conventional engines, a well-engineered evacuation system also permits the use of low-tension oil rings and low-drag compression rings for even greater frictional loss reductions. Allowing the use of lower-tension piston rings for less friction.
