The Fuel Saver 7000-MPG was dyno tested and road tested on a 2008 General Motors HHR 2.4 liter engine. Our thanks to Mr. Robert Beaty who financed and performed the following tests:
Dyno Test: GRADE - Improved
BEFORE: 171 hp 6200 163 tq 5000 stock
AFTER: 180 hp 6200 171 tq 5000 improved
Dyno Test Note: This was not simply a spike at the upper rpm. The additional power was from off idle all the way to red line. The Fuel Saver 7000 resolved a lean spot at 3300 rpm. This actually was 13 hp over stock at 3300 RPM’s.
Road Test: GRADE - Improved
45 mph - BEFORE: 34.1 MPG AFTER: 43.3 MPG
55 mph - BEFORE: 32.2 MPG AFTER: 41.1 MPG
65 mph - BEFORE: 30.1 MPG AFTER: 39.1MPG
Simply Put,
Here's How It Works
?Liquid gas enters the Fuel Saver 7000-MPG through a fuel delivery line marked in "Rose Color" in the sketch.
?The liquid gas and light emissions from the engine are vaporized through a 3-Stage "cold vaporizing vacuum system".
?The vapor gas (Combination of gasoline vapor and light emissions vapor) in the sketch is injected directly back into the intake manifold through the Positive Crankcase Ventilation (P.C.V.) line.
?The liquid gas going to the fuel injectors is decreased to compensate for the added vapor gas produced from the Fuel Saver 7000-MPG. (The oxygen sensor detects the added vapor and sends a voltage signal to the computer. The computer (PCM) is pre-designed by the auto manufacturers to maintain a 14.7 parts air to 1 part gasoline VAPOR ratio and instantly reduces the flow of liquid gasoline to the injectors to compensate for the added vapor by the Fuel Saver 7000-MPG into the engine. Your vehicle is still producing the same gas vapor to air ratio as before, only now you are vaporizing your fuel more efficiently, thus producing better gas mileage more horse power and cleaner emissions
