CR Change



LOL! How can we assume stuff when the graph only goes to 13 to 1?
Not very easy is it John. Same deal for percentage changes with 16 to 1 engines and 930 hp engines.
Bet Craig would have killed for a 930 HP engine when he and Kern wrote the book. So then you have to
go with real data like single cylinder engine testing where a full sweep of the engine's compression ratios
is done and the power levels documented.

It was a basic Generic question and we gave generic answers, so how about we call this one a TIE?
So what data did you base your calculator program on? Smith, Vizard, Speed Talk?

About Us

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
