MODIFIED TO RUN ON E100! Stock for stock is DOES NOT give more power. It has lower energy density. The E100 engine HAS to be higher compression to get better mileage/power, and higher compression is more efficient.

E85 or 100% ethanol would be good if the majority of us could take advantage of it...but since we don't all have turbo's or 15:1 CR, we're just losing power and mileage.

Nope. Engineers at a Swedish car manufacturer (I don't remember if it was Saab or Volvo) did a comparison a few years ago. Two identical SUVs, one with a gasoline engine, the other one with the same engine modified to run exclusively on E100. The E100 engine showed more power, and a 18% increase in gas mileage.
If you want to keep your engine's compatibility with gasoline, your gas mileage will go down, but if you modify your engine to run ethanol exclusively, due to the increased thermal efficiency of higher compression engines, the mileage goes up.

A 15:1 compression ratio is just a shave away. You don't need a specially designed engine.
You can either deck the block and head enough, you can use domed pistons, or you can get a crankshaft with a longer stroke. Of course it will take some experimenting, but so does any other modification you want to do on an MX-3.

If you want you can run E85 on your race car, don't run it on your stock car. Case is closed.

i seriously thinks it helps.

you think so or you know so? Really, we need proof it works. You can't really says "ya it works" unless you have data to prove it.

ever since i put it in my tank. my car quit sputtering. on take off and steady speed.

? teach me how to collect that data.
