O/T Compression ratio and supercharging

[dzorde at erggroup.com]

Hello fellow diy's,

Been of the list a while as I have changed jobs (took a while to get a new email
going).  Anyway, I tried getting to Bruce's calculation page as I was hoping for
a guiding formula for selecting compression ratio (CR) based on s/c boost,
however I keep getting the message the page is not available (anyone else having
problems accessing it from the efi332 home page ?).

Does anyone have anything I can use as a guide for calculating max possible CR
on a forced induction engine ?  I know the standard formula but it doesn't take
boost into account.

If there is no such formula, what would be a feasible CR in a Fiat 903cc motor
running max 16PSI boost ? (8:1, 7:1 ?)  Looking at running on standard 96 octane
leaded or possibly 100 avgas.

Thanks in advance
