Anyone else mod other than for econmoy.

[cleanspeed1]

I've been around high performance all my life, and I love speed, but the problem is that after seeing the same combos being done over and over, it got boring and expensive.

Now the new challenge is getting max mpg out of every combo with the available fuel, at least until I can find another fuel to run that's cheap or free.

I've got a wife and family to take care of, and anything that can keep more money in my pocket and keep them healthy, I am going to do. And maximum efficiency means clean air and lower operating expense.

I'd say Eco is about proportional to the inverse of the cubic root of power.


(A car of the same era and size can have eight times the power and only have twice the fuel consumption)

A car is a tool and it doesn't take alot of power for it to do the job it needs to do and it's limited by where it's used, what good is more power when you have traffic an 65mph speed limits?

I think in practice it is more plain inversely proportional however, due to behaviors like over-accelerating (and related over-braking) and lots of idling and long warm ups and aggressive use of extra horsepower. You have to account for the typical driver and mentality for a certain type of machine.

Besides there are more examples of like a 60hp metro getting 3 times the mpg of a 160 hp american car. And said metro will not get 70+mpg if you operate it at 60hp. So I think it is a reasonably valid equation myself. eco=1/hp.

Also a larger displacement engine will have larger pumping losses when the throttle is partially closed (which it will be most of the time-moreso than a smaller engine with more load), and it typically weighs more. And Turbos are not good for BSFC on gas engines typically.

There's plenty of yahoos who *wish* they can have their cake and eat it too, but there are practical limitations in the way.

Having a car that is reacting much faster and that is accelerating faster than some cars tuned for performance is a little pleasure that I put in the face of some young people that are laughing at my car

Why do you visit Ecomodder ?

Cleanspeed,
Nicely put.
Probably reflects the sentiments of a lot of people on this board.

The actual relation between installed power and averaged actual fuel consumption, as averaged from the database of spritmonitor :

Power vs. mileage - Spritmonitor.de

The fuel consumption numbers above the bars are in Liters per 100km (62.1 miles), so higher numbers also mean higher fuel consumption.

Engine power in kW is given below the bars, and indicates a range from -10 to +10 kW around the given value.

REV-X -

I think the most impressive I read was a dude with a 1st gen Mitsubishi Eclipse (or Plymouth Laser). He had a fuel controller that he used to lean out the car in normal driving (most likely violating emissions), which kept him in the 40 MPG range. But he was also able to take it to the racetrack on the weekends.

Do you know what his name is and how lean did he go?
