Actually, even methane (or good CNG) isn't a good option... once you
get over about 10.5:1 effective compression, methane burns hotter than
gasoline... and it already burns significantly slower than gasoline.
The result is ridiculous EGT's. I've heard that 14:1-14.4:1 is the
limit for a naturally aspirated methane fueled engine because you start
melting the plasma off the top compression ring... not sure how that
would translate for a boosted engine. You can make more power with 114
octane high-lead race gas, anyway.
