Larry,
thankyou for that info. Everytime I come here I learn something. I had no idea (but it makes sense) that each gas has its own stochiometeric ratio.
Having had a day to mull over my question and understanding where I may have been vague, I'll try to ask it again, by being more specific.
When running Nos, how much more fuel has to be added?
The bigger the shot the richer the ratio, before the NOS?
eg: a 10hp shot would need a pre NOS ratio of say 13.5 and a 50 hp would need a pre NOS ratio of 12.2 (the numbers listed are just to provide an example, not to be taken as a guess nor as gospel).
And to clarify; I was only thinking of adding a 10hp shot, if it could be done with my "choke". I am not interested in making mondo hp...
Wobbly,
Exactly as I was thinking....
And yes you are right, the combustion chamber is relatively modern, it has Suzuki's first Gen TSCC.
