Racing tricks gives 90mpg from V8

Mythbusters busted this one--you know something that they don't?

Nice video, however a few points were not covered that are widely discussed over the Internet:

Acetone can harm fuel lines where they are nonmetal, injectors, fuel pump.

Also, if you increase the advance then you get detonation ignition in lower rpms.

Also under higher fuel pressure I presume it is meant richer fuel mixture?

I like the cold air approach with ice, sounds interesting!
