Hey gang,

I need to get factory documentation of the stock compression ratio for the 944S. I'm not interested in the 8v or the S2 or any other model.

What I need is a scan of either the FSM or the owner's manual. I have a copy of the FSM on CD, but my computer is not reading it. Anyhow, a page from the CDs would be OK as well.

This is for clarification for the SCCA in my role as a member of the Improved Touring Advisory Committee, so factory documentation is essential. While I might trust you, "trust me" does not work for making rules.

So, can anybody help me?

 

10.9:1

Thanks. Got documentation?

 

would maybe a factory brochure work or does it have to be out of the manual?

 

Here it is straight from the FSM:

 

Super duper! Thanks!

While I said I didn't need any other models, it turns out I do need the CR for the 2.7. You wouldn't happen to have that one as well would you?

 

Lemme check. Can't seem to find anything, I have the early engine, and the 88 engine (10.2:1) but don't have the 2.7. I have all 6 volumes in PDF, too...Hmm...
