Greetings!

I just found this forum. I'm a long time alternative fuel guy, with 30+ years of race car, economy tuning and fabrication experience. I'm interested in all of it.

My very first car, a 1966 Mustang with a 200 cubic inch six was modified for exceptional fuel economy. I raised the compression to 11.7 to 1, removed the stock 1 barrel carb and installed a progressive 2 barrel Weber. (plenty of other mods too). The MPG went from 23-25 to 32. And, that was my first attempt!

More recently I've been driving modern diesels with 42MPG. I still own an older Rabbit diesel too.

I'm currently working on aviation related projects. Next, I'll be testing some alternative unleaded fuel in our companies high performance aerobatic aircraft (an Extra 300L with a BPA high compression engine)(Experimental). The fuel I'll be testing is made by Swift Fuels and is really about 104.9 octane, but is named 100SF. They also make an experimental unleaded fuel with 115 octane. The bio-fuel, 100SF is a likely candidate to replace the leaded Avgas we use today. So, I'm excited about the project. It's been a long time coming.

Believe it or not, these "old tech" modern, injected aircraft engines have BSFC numbers far better than the best automotive engines made today. Our Lycomings regularly operate at a cruise BSFC number of 0.38 pounds of fuel per hr per HP produced.

My personal 4 seat Cessna 177RG gets between 17.4 and 21.1 MPG at speeds ranging between 145 and 163MPH. Plus, it goes direct, eliminating an average of 25% of the distance traveled if you drove. Making the MPG equiv. about 23 MPG at 160MPH. The use of 100SF would increase the MPG by an additional 15% due to energy density (it's a heavier fuel).

Much of what I've learned in the automotive world transfers to aviation. And, vice versa.

Thanks,

I'm not the "smart" guy you think I am. I am here to learn from all you smart guys. There is a wealth of information here. Not simply "what to do" but plenty of experimentation too.

A car that really appeals to me is the plug in Prius and/or Volt. I build my own solar panels and could use this "free" electricity to improve MPG.

Could you post some pictures of these engines? I am just a nut for high performance steel!
