Yes there is just don't know about M5 because it will not pass fuel test in NHRA?WPH wrote:Anyone tuning with WideBand? What kind of lambda values are safe to tune into?
Any differences between methanols, for example normal versus M5?
There are way too many variables on egt's to say that as a blanket statement. I've seen many alcohol cars slow down anytime they get above 1250. Header material, wall thickness, coated or not, dragster (headers out in the open air) door car (headers under the hood) location of the egt probe, ENGINE COMPRESSION RATIO, etc. all have an effect on the egt reading. I usually tell racers to ignore the egt. (within reason) and tune the car for MPH, once you are satisfied with the performance, take an egt reading and use that for a reference in the future. All cars will be a little different.SonnyJames wrote:I was told by a well known carb builder that 1290 is good and 1320 is best power. Just so happens mine is 1310 at the 1/4 finish. With that reading is a 11.8 reading on the 02 most of the way down the track.
