Negative Pressure Supercharging is a highly advanced 6 cycle supercharging combustion process that produces substantially more torque and horsepower and much lower fuel consumption and emissions over a lower and wider rpm range than the old 4 cycle process used by today’s engines
Produces MORE average torque than 650-700ci engines which produces faster acceleration and 30-50% better fuel mileage than engines with more peak horsepower

ie:
318 Impulse Crate Engine

Stage 4 : 480 lbs/ft torque 1500 – 3500 rpm 330 hp at 4500 rpm
Stage 6 : 570 lbs/ft torque 1000 – 3500 rpm 380 hp at 4500 rpm
Stage 7 : 630 lbs/ft torque 1000 – 3500 rpm 420 hp at 4500 rpm

360 Impulse Crate Engine

Stage 4 : 540 lbs/ft torque 1500 – 3500 rpm 380 hp at 4500 rpm
Stage 6 : 640 lbs/ft torque 1000 – 3500 rpm 440 hp at 4500 rpm
Stage 7 : 710 lbs/ft torque 1000 – 3500 rpm 480 hp at 4500 rpm

Very interesting…..Hmmmmmmm.

Is the patent owner/manufacturer though these is a dealer in the US. I’ve been watching them and others for years. Be great to see them actually get something widely distributed!
