The Blade - Increase Fuel Economy by 30%?

[tasdrouille]

The gas mileage reduction percentages are understated due to the fact that the car is tested in a laboratory. On a dynamometer a car will get much higher gas mileage than on the road. The 2004 Honda Civic got 53 MPG on the Highway in the laboratory, and the increase with the Blade was 6%. If the 5 MPG HWY fuel economy increase was calculated against the car’s actual gas mileage, the percentage increase in fuel economy would be closer to 25%.

The same 2004 Honda Civic was road tested for 6-months and the average gas mileage increase has been approximately 30%.

Some people will actually fall for this...

This blade thing sounds like a scam.
It adds back presser giving the engine more work to do trying to push out the exhaust !
If you want a good efficiency with the exhaust, you need to do just the opposite.
The less back pressure the better up until the point at witch you start to burn valves
