Actually the stoich or lambda 1 for methanol is 6.45 to one.SPEEDSTAR said:Isnt the ratio of methanol to air roughly 6 to one , this I see in his meth values. This is lambda .941.....This is right on Don's best engine torque lambda of .9. So target lambda .941 and watch egt's for 1200 to 1350....JEFF
As the chart shows, stoich for any fuel will always be lambda value '1' period. Richer or leaner from stoich is a percentage value of lambda one. I have some ratios that pertain to methanol such as rich best torque, lean best torque etc. I'll dig those numbers up and share them. It will be interesting to see how those numbers compare to gasoline rich best torque (12.8) and lean best torque (13.3) on howracer's chart. From this day forward to be known as 'THE CHART'.
