Have anyone of you out there done something along the lines of catalytic converters, ethanol fuels (ethanol or E85: 85% ethanol + 15% gas) etc?
Is it at all possible to make an ACVW engine reasonably environmentally friendly? Preferably with decent performance/reliability as well?
If so, what type of engine configuration would be suitable?
Please let me know your thoughts on this subject, it would be cool to drive a “green” ACVW!

The problem with performance A/C engines is that they are cooling-limited, so the tendency is to use excess fuel for cooling during times of high output. This does not do much for emissions!
Even with alternative fuels you will have to run rich to prevent detonation at higher outputs.
