<VV> Head milling, was: PG Turbos??

[Dennis & Debbie PLEAU]

I think the idea is you can take a "high compression" Corvair engine that 
already requires premium gas and increase the compression ratio a little bit 
and and increase the turblance so you don't get pinging.  Same octane a 
little more power because of the increased compression ratio and the same or 
less pinging because of the increased turblance.  I've never heard you can 
burn regular.
