Hair Dryer Power!

You could go to www.scaguage.com for a product that is pretty good for monitoring mpg. Also, if you want a product that is really good for monitoring engine parameters such as O2 sensor outputs, long and short term trim levels and such, this is a pretty good product: http://www.auterraweb.com/ Welcome to the group!

If your car is made after 1996 Scangauge is your best bet. It will monitor air temp, engine temp, mpg, etc. I'm not certain about data logging though, but I'm pretty sure with obd2 (post 1996) you can easily get toys for things like this.

For those of us with older cars, we're still trying to figure out the best way to monitor gas mileage. We'll figure something out sooner or later.

I have a 1951 truck with a 96 Ford engine but I did not use the computer. Thanks for the links. I'll look at them.

yes, fuel will vaporize better in warm air, but your engine will run more efficently if it has cold, dense air because it gives a simaler affect as a turbo, and if done right, a turbo engine can get the same mileage, or better, while producing more power, becasue of the extra air it's packing in there.
and a hair dryer doesn't produce enough presure to make any differnce, it might put out .5 psi, while a turbo is 15-20 psi, or more.

I'm glad you're going around ressurecting some old threads, , some of these things have nuggets in them.

Yanno, it just occurred to me that the easiest warm air intake system would be a tube with an orfice that pushes a metered amount of EXHAUST GAS into the intake manifiold. EGR has been used for years to reduce NOx emissions, so why not apply it to fuel economy?

The tubing would be tiny compared to hair dryers, catalyst shrouds, and ducting from the catalyst, etc. And the whole thing would be reversible at inspection time.

Has anybody tried this?

At first I was like who brought up the hair dryer thing again! But there's more to it. You're right, despite the title, there might be some valuable off-topic gems to mine.

Well, from my standpoint, the egr system that honda designed has not just emissions purposes, but gas mileage purposes as well. I will be doing this buy installing a stock intake manifold and egr system in the future.

How do you plan to scoop up the exhaust gasses though?

Also from my standpoint GM designed my egr system on my engine to also affect FE in a positive way (the 60°V6 guru/ecu programmer I know mentioned this when I told him i was interested in piggy-back chipping my motor)

at what point does the EGR valve open? and would leaning out the o2 in your "air" really have that much of an affect? I meen, I'm sure you could lower the amount of fuel going in if you lowered the o2, but wouldn't you almost need to cool the exaust gasses befor the go in the combustion chamber, so they can exspand again with the rest of the gasses?
and would you have a problem with the o2 being to scattered to be able to burn all the fuel?
